How Often Does a Hydroponics Tank have to Be Cleaned?

Hydroponic systems supply a cost effective, space saving way to increase crops year round. The roots float within a solution of water and nutrients that needs to be routinely replenished or flushed. To keep the plants healthy, a hydroponic garden requires constant, weekly care.

A Simple Answer

Hydroponic solution can be altered and the tanks sterilized as often as once per week. This type of constant turnover will block you from having to top-off the option and also throw off the balance of nutrients. But while this is the easiest answer, it may be more work than needed. Based on the magnitude of the cylinder and reservoir, species of plants and exposure to heat or humidity, you may have the ability to change it considerably less often.

A Complex Answer

To determine when to change the mineral solution to your exact installation, monitor water level, pH and electric conductivity (EC) in the reservoir. Measuring the EC provides you a great idea of the concentration of nutrients, since it is a measure of the dissolved salts inside water. Begin with a new tank of option. As the water level decreases over the week, top off the reservoir. Utilize a simple test kit to assess the pH and EC and add as many nutrients as recommended by the manufacturer based on your readings. When the total amount of water solution you’ve added equals the capacity of the reservoir, drain the machine, sterilize it and then replace it using new option. For instance, in a 10-gallon reservoir, you may lose and replace about 2 gallons weekly. Within five weeks, you would have replaced 10 gallons of water, meaning you should flush and sterilize the machine every five weeks.

Disease Problems

Cut away dead leaves and remove decaying stuff from plants on a regular basis, since they can bring about disease development. Any time you find a diseased plant, you have to flush and sterilize the machine. Eliminate any sick plants and dispose of them. Pythium, or root rot, is perhaps the most common and detrimental disease in hydroponics. It’s almost impossible to save an infected plant, so remove even the ones that appear somewhat healthy despite their infection to prevent the spread.

Clean Period

Based on writer Eric Hopper in a post for your own gardening journal “Maximum Yield,” hydrogen peroxide would be the ideal alternative for sterilization. It’s simply water with an unstable oxygen molecule so that it breaks it down, it becomes water, leaving without poisonous chemicals. But highly concentrated hydrogen peroxide can readily burn body, so always wear protective clothing such as gloves and eyewear while working with it. Use 35 percent hydrogen peroxide and dilute it 2:1 with water. Run it through the program for one hour. Wash the whole system with clean water before putting the nutrient solution and your plants back in.
