Hydroponics System Daily Maintenance Check List



Once a growing system is up-and-running, to successfully grow hydroponic plants, there are only a few tasks required. Check the system daily or every other day and do the following keeping in mind the 5 basic requirements of plants (light, water, nutrients, temperature and oxygen).

  • Most plants love humidity so mist them continually and they will be happy.
  • Watch the system and make sure it is performing properly. If it floods the plants and drains at a specific time – verify this. Small bits of growing medium can clog the tubing of a system in no time flat and either leave your plants ‘high and dry’ or continually flooded. This happened to me once.
  • As your nutrient solution evaporates, add tap water to refill it to where it should be. Do not ever add a touch more of nutrient powder to replace what you think has been used up. This is a really good way to kill your plants.
  • Keep an eye out for pests and disease as well as nutritional deficiencies.
  • Take care of any problems as fast as possible or they will grow into large problems faster than you will believe.
  • Take a look at the plants. Are they wilting and is the growing medium completely dry? Or is it continually soaked? Adjust the amount of nutrient solution accordingly (this is for systems that periodically receive nutrient solution most likely through a timer).
  • Dead growth saps the energy of a plant and can be a good beginning for a disease or pest problem so keep the dead matter pruned.
  • Keep track of the temperature if you are in a greenhouse and ventilate if necessary by opening doors, windows and turning on a fan.
  • In an enclosed area like a greenhouse, let some bugs and breezes get in. This not only helps with pollination but some bugs will actually protect your plants by eating the bad ones.
  • Learn to identify the good vs. bad bugs. Dragonflies, spiders and ‘daddy long legs’ are good to have around – they eat the bad bugs so encourage them. I personally love dragonflies – I’ve seen them dive-bomb horse flies and moose flies and eat them.
  • Keep a log. What becomes second nature to you now will probably be completely forgotten in a few months so write it down.

I know this seems like a lot of effort but once you get a routine down you may not need more than a few minutes a day to perform these tasks. Keep up the vigilance and you will grow hydroponic plants that are healthy and you will be amply rewarded with a large amount of vegetables and herbs.

Hydroponics, the high-tech gardening method enabling year-round growth regardless of location, has become a mainstay in urban farming. An indispensable part of this system is water, and heavy-duty steel water cartage tanks play a key role in this area, offering durable storage to maintain fresh and clean water. Let’s explore more about optimizing hydroponics using these tanks.

Understanding the Basics: What is Hydroponics?

Hydroponics is growing plants without soil. Replace soil with a nutrient-water solution delivered directly to plant roots, and you’re engaging in hydroponics! The beauty of this method is that you’re in full control over the conditions of growth – pH levels, nutrients concentration, light exposure and more – creating an ideal environment that encourages robust growth.

A Closer Look at Water Tanks in Hydroponics

In a typical hydroponic system, water tanks are pivotal components. These tanks serve as reservoirs storing the nutrient solution that gets circulated around your system. They come in various sizes and materials but one stands out for those who prize longevity – heavy-duty steel water cartage tanks.

Essential Components of an Efficient Hydroponic System

Optimizing your hydroponic garden means ensuring each part functions optimally for a seamless operation. Sure enough, water tanks play a crucial role but remember there’s more to consider – from grow lights ensuring appropriate light exposure regardless of whether it’s day or night to nutrient solutions providing precisely what your plants need to thrive.

Water Quality and Its Effect on Plant Growth in Hydroponics

It’s not just about having water; the quality matters too when it comes to hydroponic systems. Healthy plant growth depends heavily on clean, uncontaminated water loaded with essential nutrients. Using reliable storage like steel water cartage tanks helps you maintain this standard consistently.

Optimizing Water Usage: Key Strategies for Hydroponics Farmers

Let it be known that with hydroponic systems, optimizing isn’t limited to choosing good-quality equipment like trustworthy steel tanks; it extends to efficient water usage too! Employing strategies like regular monitoring and real-time adjustment of factors such as nutrient concentration can see your garden bear fruitful results.

Environmental Impact of Hydroponics

Many naysayers may argue that hydroponic gardening requires more inputs compared to traditional techniques – but you’ll know better! With smart strategies optimized around sustainability – using energy-efficient grow lights or designing systems around high-quality durable tanks – you can maintain resource-friendly practices.

Adapting Based on Feedback

Moreover in hydroponics, flexibility is virtuous. It allows you to tweak processes based on feedback from your plants. Be ready to adjust light hours, enhance nutrient concentration or perform comprehensive cleanses on your steel tanks whenever necessary.

Decoding the Hydroponic Water Cycle

Just as nature has its water cycle, so does a hydroponic system. However, in hydroponics, this cycle is much more controlled. It begins with the water in your storage tanks being infused with essential plant nutrients. This nutrient-rich solution is then delivered to your plants’ root systems. Post nourishment, the unused water is returned to the tank for re-circulation. In this cycle, your heavy-duty steel water cartage tanks serve as pivotal reservoirs and recirculators, ensuring your plants never lack nutrient-rich water.

Light, Temperature and Water in Hydroponics

Optimizing your hydroponic garden involves perfecting a delicate balance between light, temperature and water. While light and temperature influence photosynthesis and growth rate respectively, you use water as both a hydration source and transport medium for nutrients. It’s crucial then to ensure that your heavy-duty steel water cartage tanks are always filled with clean, nutrient-rich water- ready for use when needed.

The Future of Hydroponics with Optimized Water Tanks

To wrap up, start your optimization journey today. It’s about small, conscious changes – picking durable equipment like heavy-duty steel water cartage tanks and refining your gardening practices.

4 Tips for Successful Hydroponic Growing



4 tips for successful hydroponic growing 5

With the global population growing at a rate of approximately 1.05% per year or 81 million people annually, the increased demand placed on the Earth’s natural resources calls for new and innovative solutions to farming methods and food production.

One possible solution which has developed in the field of horticulture is a method of growing plants known as Hydroponics. Here plants are grown without soil, by using a nutrient-rich growing medium such as coco coir, gravel, rockwool, or sand, allowing for nutrients to be absorbed directly into the plant’s roots.

Without the need for soil, crops such as corn can be grown throughout the year, resulting in higher yields and fewer fluctuations in price. If you are looking for some growing tips for your hydroponic plants then read on.


Before plants can be introduced to a hydroponic growing system it is important to check the quality of your water supply to ensure the pH levels are correct. Ideally, the water should have a pH of between 5.5 and 6.5 which can be measured using pH strips or a pH meter.

EC or Electrical Conductivity levels of water measure its ability to dissolve salts and other chemicals and should also be checked to ensure your plants receive the nutrients and minerals they need from the water. The temperature of the water should be kept between 68°F and 72°F and can be maintained through the use of a heater or chiller.


One of the most important factors when it comes to hydroponic plant growth is light. Grow light for indoor plants is an essential factor in the cultivation of hydroponic plant growth, especially when there is less sunlight available.

Light-emitting diode lamps or LEDs are a preferred method for many growers due to their efficiency and effectiveness and their full spectrum of light which is similar to the rays of the sun.  Lighting can also be adjusted according to the life cycle of your plants.

Growing Medium

The right growing medium is another essential step when it comes to your hydroponic success. Due to the absence of soil in this method plants must be supported in other ways. 

The growing medium must have the right combination of oxygen and moisture allowing for nutrients to be properly absorbed by the roots of the plants. Coco coir and rockwool are some of the popular mediums used by growers as they retain moisture and oxygen well.


Without the presence of soil to nourish your plants, hydroponic plants will require nutrient-based solutions which are specifically designed for growing plants hydroponically.

Hydroponic plants need 17 essential nutrients in order to grow and develop properly, therefore, a good quality nutrient fertilizer will be required.  With a variety of nutrient-rich fertilizers on the market to choose from it is advisable to purchase from a reputable supplier and to ensure the solution is right for the types of plants you are growing and the stage they are at in their life cycle.

These four tips will help to ensure the success of growing your plants hydroponically.

Hydroponic Nutrients – The Essential Elements



Hydroponic nutrients - the essential elements 7

Hydroponic-nutrientsThere are 17 essential elements needed for plant growth. Three of them (hydrogen, oxygen, and carbon) are non-mineral elements and are absorbed by plants through the air or water. The other 14 essential elements must be provided by the soil or fertilization. Since hydroponic gardening bypasses the soil, all 14 essential mineral elements must be furnished in the hydroponic nutrient solution.

These essential mineral elements are broken into two categories: macronutrients and micronutrients. The macronutrients are the nutrients used in higher concentrations relative to micronutrients which are absorbed in smaller amounts. When shopping around for hydroponic nutrients, a gardener will quickly notice three numbers on the nutrient solution’s label. These numbers represent the N-P-K values or ratios of nitrogen (N), phosphorus (P), and potassium (K) in that particular formula. Nitrogen, phosphorus, and potassium are the primary macronutrients. In other words, they are absorbed in higher ratios than any other essential mineral element. This is why it is important for fertilizer labels to disclose the N-P-K ratio. A closer look at all of the macronutrients found in hydroponic fertilizers will give growers a better understanding of how each element affects plant growth.


Nitrogen (N)

A basic component of proteins and chlorophyll, Nitrogen is the main nutrient responsible for vigorous growth and luscious green coloration.

Phosphorus (P)

Plays an important role in root stimulation and establishment for young plants. Phosphorus also promotes flowering, fruiting, ripening, and respiration.

Potassium (K)

Promotes movement of sugars and other nutrients (via osmosis). Potassium is directly linked to stem strength and rigidity. Potassium increases a plant’s overall resistance to cold, drought and pathogens. Much like phosphorus, potassium plays an intricate role in the formation of flower buds and fruiting/blooming processes.

Calcium (Ca)

Builds and becomes part of the cell walls. Calcium is vital to plant structure and strength and promotes growth of young shoots and roots. Calcium is needed for ripening and seed production.

Magnesium (Mg)

Reinforces cell walls and is an important component of chlorophyll. Magnesium promotes the absorption of phosphorus, nitrogen, and sulfur. It also plays a vital role in the ripening of fruit and the germination of seeds.

Sulfur (S)

Contributes to chlorophyll production and is a necessary component of several proteins, enzymes and vitamins. Sulfur aids the plant’s absorption of potassium, calcium, and magnesium.


Micronutrients, although absorbed in lower amounts than macronutrients, play an equally important role in overall plant health.

Chlorine (Cl)

Involved in the stimulation of photosynthesis.

Iron (Fe)

Assists in biochemical processes, including the manufacturing of chlorophyll. Iron also contributes to the formation of some enzymes and amino acids.

Boron (B)

Essential for tissue growth within the plant. Promotes the absorption of water and helps regulate a plant’s metabolism. Boron also assists in the formation of fruit.

Manganese (Mn)

Plays an essential role in nitrogen assimilation and protein formation. Manganese can speed up a plant’s maturity and helps promote seed germination. It is also necessary for chlorophyll production.

Zinc (Zn)

Helps the development of enzymes and growth hormones.

Copper (Cu)

Plays a role in chlorophyll production and helps activate various enzymes.

Molybdenum (Mo)

It is needed for the production of nitrogen-based proteins and is essential for nitrogen assimilation by plants.

Nickel (Ni)

Regulates mineral metabolism, enzyme activity and other metabolic processes in plants.

Hydroponic Base Nutrients

There are many choices and it can become overwhelming trying to choose a brand of hydroponic nutrients (fertilizers). The first thing a hydroponic horticulturist should do is choose a base nutrient formula. A base nutrient formula will contain all the essential mineral elements, therefore providing all elements necessary for plant growth. Depending on the manufacturer, the base nutrients may be a one, two, or three part formula. Regardless of how many parts it is all base nutrient formulas do the same thing: provide the plants with the essential mineral elements. A good hydroponic base nutrient is all that is needed to get started growing hydroponically.

Can I Use my Hydroponic Nutrients for Soil Gardening?

Hydroponic base nutrients are designed specifically for use in hydroponic systems. Although they can be used in a pinch to fertilize plants in soil containers, they are designed for hydroponics which means the ratio of some elements will differ from fertilizers designed specifically for soil.

pH in Hydroponics

In order for the plants to absorb the essential elements in a hydroponic system, the pH of the solution must be in a particular range. A pH of 5.5 – 6.0 is the desired range for most hydroponic systems. If the pH gets above or below that range, the plants will be unable to absorb certain nutrients. This will eventually lead to a deficiency. Hydroponic growers will need to have pH buffers (pH up and pH down) on hand to make adjustments when necessary.

Finding a hydroponic nutrient formula can be overwhelming for new growers. Just remember, a good base formula and pH buffers are all you need to get started. Once you feel comfortable with your base formula, you can begin experimenting with the plethora of hydroponic nutrient additives available at your local hydroponic retailer.

Hydroponic Systems in a Greenhouse



Hydroponic systems in a greenhouse 10

Accessibility to information, due mainly to the internet, has many home greenhouse hobbyists experimenting with hydroponic systems in a greenhouse. Hydroponic gardening is gardening without the use of soil. In other words, any type of growing system that bypasses the microbes in the soil and directly feeds the plants with nutrients can be considered hydroponics. There are many different hydroponic growing systems and each has its own advantages and disadvantages. A closer look at some of the systems commonly used by home hobbyists will give a grower a bit of insight into the fascinating world of hydroponic gardening and some inspiration to start experimenting.

Deep Water Culture

Deep water culture is perhaps the easiest hydroponic system to set up. A five gallon bucket or tupperware container can be converted into a deep water culture system with just a few parts from the hardware store. In a deep water culture system, the plant is held in place by a small amount of inert medium (usually gravel or clay pebbles). However, the vast majority of the plant’s roots do not grow in the medium, but, rather, dangle down into the container where they are submersed in the nutrient solution. These systems are great because they are easy to build and can produce quick, vigorous growth. The biggest drawback of deep water culture systems is how susceptible they are to temperature changes. Since the roots are submersed in the solution, the temperature of that solution will greatly affect the way the plant’s roots can receive oxygen. When temperatures are too warm, the plant’s roots will not receive the oxygen they require and they will become susceptible to pathogens. For this reason, deep water culture should only be used by greenhouse growers in cooler climates or growers who have invested in cooling devices, such as water chillers or air conditioners. Without a cooling device, a grower may have a difficult time keeping the system’s temperature in the desired range (65-75 degrees F).


In a top-drip hydroponic system, the nutrient solution is delivered to each plant via a drip stake or drip line emitter. The individual plant modules will vary from system to system, but, generally, top-drip gardeners use standard potting containers. The medium for the containers can be any sort of inert medium or even soil if the grower wishes to have a more hybrid hydroponic/soil system. Top-drip systems can be set up as a recirculating system or a run-to-waste system. Recirculating top-drip systems will need a reservoir for holding the nutrient solution and the reservoir will need to be aerated. A timer is needed to trigger the pump for feeding intervals. The duration will fluctuate depending on the crop being grown and the particular stage of growth. Although top-drip systems are a little more expensive to start up than a deep water culture system, they fare much better at higher temperatures. Top-drip systems are also the preferred hydroponic system of commercial tomato growers.

Flood and Drain

A flood and drain system uses a table or trough which is flooded with nutrient solution for a given period of time and then drained. Traditional flood and drain systems use gravity to return the nutrient solution to the reservoir. In other words, once the pump that pushes water to fill the flood table is deactivated, the water drains back to the reservoir. Typically, containers filled with a medium, such as hydroton, stone wool, coco coir, or another soilless mix, are placed in the flood tables; however, the medium can also be placed directly in the table or trough. Flood and drain systems work well for hobbyists looking to experiment with hydroponics and/or beginner gardeners because they are easy to build and can accept a wide range of media. Like top-drip systems, flood and drain systems can offer a hybrid hydroponic/soil system to growers who are not ready to give up soil gardening completely, but still want to gain some of the benefits hydroponic gardening has to offer.

The previously mentioned hydroponic systems are commonly used by beginner hydroponic growers or hobbyists looking to do a little experimenting with hydroponics. Other systems, like aeroponics, nutrient film technique, and current culture, can also be used, but are typically reserved for growers with more hydroponics experience. That being said, remember that experimentation with hydroponic systems is a fun and exciting way to differentiate your greenhouse from others. There is no shame in trying out a new hydroponic system or trying to develop your own system for your particular greenhouse. Like other styles of gardening, hydroponic systems offer a lifetime of learning to anyone willing to give it a try.

Why Use a Growing Medium When Gardening With Hydroponics?



Growing plants using hydroponics means you are growing without soil, but it doesn’t necessarily mean that you are growing plants without a soil replacement. While not strictly necessary it is usually advantageous to use some form of growing medium. One very good reason to use a growing medium in your hydroponics garden is to ensure that the roots of your plants are adequately supplied with oxygen. In a traditional garden plant roots gather oxygen from the air trapped in the soil. A growing medium serves the same purpose for plants grown with hydroponics. Growing media are designed to trap air that can then be processed by the plant roots.

Another reason for using a growing medium is to provide a food reserve for the plants. Like air, nutrients from the feeding solution are trapped in the pores of the growing medium and are then available to the plants if needed. This can help to prevent crop failures. Here’s a quick rundown of the kinds of media available to you when gardening without soil.

Types of Growing Media


Made from basalt rock and chalk, Rockwool is probably the most popular growing medium used by hydroponics gardeners. This porous material can trap large quantities of air and water at the same time.

Perlite and Vermiculite

Perlite is a pebbly volcanic rock that provides excellent drainage and aeration when used as a growing medium. It has a good drainage characteristic which means it does not hold much water and limited ability to trap nutrients. Vermiculite is a mineral that acts like a natural wick and is able to absorb large quantities of water. The combination of Perlite and Vermiculite is a natural for hydroponics system: one holds air and oxygen, the other holds water and nutrients.

Coconut Fibres

Made from the outer husks of coconuts this growing medium is becoming increasingly popular with organic growers. Some hydroponics growers feel coconut fibres are superior to Rockwool in their ability to retain air and water.

Expanded Clay Pellets

This medium is made from baked clay. The pellets are porous and retain both air and water very well. They can be reused as long as they are first sterilized.

Aquarium Gravel

This is the same colored gravel that is used in fish tanks. The main reason for its popularity is expense as it is inexpensive compared to other growing media. The downside is that it does not hold water, and therefore plant nutrients, very well at all. If you choose to use aquarium gravel you will need a constant water supply for your plants to avoid root drying.

Flood Tray Liners by Smart Pot



Flood and drain, also known as ebb and flow, hydroponic systems are one of the most popular hydroponic systems used by horticulturists. Most flood and drain systems consist of a tray (which holds the plants) and a reservoir (which holds the nutrient solution). The tray is set on a stand or raised up on blocks so that the bottom of the tray is higher than the top of the reservoir. In most cases, the tray sits directly above or sometimes even rests on top of the reservoir. A submersible pump within the reservoir then pumps the nutrient solution into the tray. The tray has an overflow valve installed so the depth of the nutrient solution in the tray can be controlled and ensures the tray doesn’t overflow with nutrient solution. After a set duration of time, the pump shuts down and, with the help of gravity, the nutrient solution drains back into the reservoir. As with other hydroponic systems, plants grown in a flood and drain system generally experience faster growth rates and larger yields.

One issue with conventional flood and drain systems is the growing medium used in the planting containers and how it affects the pump. Because the nutrient solution needs to enter the planting containers from the bottom, a flood and drain system requires open bottomed planting containers. Typical planting containers can be used in a flood and drain system but can cause issues due to the size of the drainage holes in the container. As the water flows back to the reservoir and out of the planting containers, it can bring with it sediment and soil that will damage the pump and possibly compromise the entire hydroponic system.

Many growers who use flood and drain systems have already discovered the great benefits of using Smart Pot planting containers. Smart Pot fabric containers can act as filtration screens for the medium. When used in a flood and drain system, a Smart Pot fabric container will allow the nutrient solution to reach the root mass but will keep all soil and sediment from reaching the pump.

Flood Tray Liners by Smart Pot

The folks at Smart Pot took flood and drain hydroponic gardening to the next level when they introduced their Flood Tray Liners. These Flood Tray Liners are made from the same great material as the Smart Pot containers and fit directly into the flood tray. These liners give the grower many different options. Growers can place the medium directly into the liner and grow their plants in a large bed or they can use virtually any planting container they desire regardless of the size of holes in the bottom of the container. The Flood Tray Liner will essentially act as a filter so that the nutrient solution is never contaminated with soil or sediment from the medium. The Flood Tray Liners by Smart Pot come in three convenient sizes which fit the most commonly used flood trays: 4’ x 4’, 4’ x 8’, 3’ x 3’. Smart Pot’s Flood Tray Liners will save a grower both time and money and are a simple way to increase the productivity of a flood and drain hydroponic garden.

Choosing a Hydroponic Fertilizer is Kind of Like Buying a Car



Upon entering a hydroponic retailer, a consumer will quickly notice the seemingly countless options available. There are many choices when it comes to choosing a brand of hydroponic nutrients (fertilizers) and this can be overwhelming for a novice hydroponic enthusiast. Choosing a hydroponic fertilizer is kind of like buying a car. There are many options but, at the end of the day, they all get you from point A to point B.

Base Nutrients

The base nutrients of a hydroponic nutrient solution do just that, get your plants from the beginning to the end. The base nutrients will contain all the mineral essential elements and will provide all that is necessary for plant growth. The essential elements found in hydroponic nutrients can be derived from a variety of sources. The varying sources will affect the formula’s stability. This leads to different types of formulas for the horticulturist to choose from. Typically speaking, there are three types of formulas produced by manufacturers of hydroponic nutrients. One-part formulas (stand-alone grow and bloom), two-part formulas (grow A and B and bloom A and B), and three-part formulas (micro, grow and bloom). A hydroponic grower will usually first choose from a one-part, two-part or three-part formula and then choose which brand of fertilizer he or she wishes to use.

One-Part Formulas

A one-part formula consists of one individual grow formula and, if it is for growing a plant that produces fruit or flowers, one individual bloom formula. One-part formulas are great for beginner hydroponic growers as they only require the dosing and mixing of one product. The stage of growth of the plant(s) will determine if the gardener uses the grow or the bloom formulation. The type of crop and stage of growth will determine the dilution rate for the particular product. One-part formulas will contain all of the essential elements needed to sustain plant health. However, one-part formulas will usually contain less than optimal levels of some of the essential elements in order to make the overall formula stable. For example, many one-part formulas contain only small amounts of calcium and rely on calcium contained within the grower’s water to make up the difference. Horticulturists using one-part formulas may, in some cases, need to supplement additional sources of certain essential elements.

Two-Part Formulas

A two-part formula consists of two parts for both the grow and the bloom stages of plant growth. In other words, during the vegetative stage of growth, both a grow A and a grow B formula will be required. If the horticulturist is growing a particular plant variety with a fruiting or flowering stage of growth, he or she will be required to use both a bloom A and a bloom B during that period. Two-part formulas offer an advantage as they are able to separate some of the elements that would otherwise create an unstable formula when mixed in the concentrated forms. More specifically, two-part formulas are able to separate particular compounds containing concentrated calcium and phosphorus which could react poorly when mixed. A two-part formula allows the horticulturist to dilute the concentrated calcium before adding the phosphorus. This is why the part A of a two-part formula will usually contain the calcium. Generally speaking, two-part formulas can contain a higher concentration of calcium and a more ideal ratio of all the essential elements than a one-part formula.

Three-Part Formulas

A three-part formula consists of separate micro, grow and bloom formulas. Unlike the one-part and two-part formulas where the “grow” is used exclusively in the vegetative stage and the “bloom” is used exclusively in the fruiting or flowering stage, three-part formulas use all three parts throughout the entire life cycle of the plants. The ratio of the three parts (micro, grow, and bloom) will change depending on the particular dietary needs of the plant and the stage of growth. For example, a pepper plant in its vegetative stage will receive different ratios of each of the three parts than a pepper plant when it is producing peppers. As the names suggest, the “micro” contains most of the micronutrients (and usually the calcium), the “grow” contains nutrients more specific to growth and the “bloom” contains nutrients more specific to blooming. Although growers will use all three parts throughout the plant’s life cycle, they will typically use a higher ratio of “grow” during the vegetative stage and a higher ratio of “bloom” during the fruiting or flowering stage. A three-part formula offers heightened control to the horticulturist and gives the ability to more quickly correct deficiencies.


After a hydroponic gardener has established an effective base fertilizer program, he or she can begin to experiment with the various nutrient additives available on the market. Micronutrient supplements, carbohydrate formulas, enzyme formulas, plant vitamins, plant hormones and beneficial microorganisms are just some of the options a hydroponic gardener can experiment with. Each garden is different and the best way to determine if a nutrient additive is truly beneficial is by way of experimentation.
