The only major difference between regular hydroponics and organic hydroponics is the fertilizer used. Since hydroponic systems don’t produce any weeds and are typically used in greenhouses or indoor grow rooms, there is no need for herbicides or pesticides in any hydroponic system. The 2 ways organic hydroponic nutrients are produced is through the making of compost tea or aquaponics.

Making Compost Tea

Aquaponics is the mix of aquaculture (fish farming) and hydroponics. Essentially to make an aquaponic system, you put certain species of fish in your reservoir, and rather than adding nutrients to the water, you just feed the fish, and allow the water to become nutrient rich via fish crap.

Aquaponics generally takes a relatively high level of testing and experience to be able to effectively use it, which is why most people use the more cost effective solution of making compost tea.

Compost tea is any kind of nutrient-rich organic matter absorbed into water. To make compost tea, first you should make compost, which is as easy as putting organic material such as leaves, grass, and kitchen scraps in a pile and allowing them to break down into a dark soil-like material. Once you have compost, dissolve let it sit in water for several days, stirring every day. Then use some kind of filter, such as an old t shirt, to collect the liquids and discard the solids. Once you have compost tea, simply add it to your reservoir.
