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.
