The two main types of hydroponics are solution culture and medium culture. Solution culture does not use a solid medium for the roots, just the nutrient solution. The three main types of solution cultures are static solution culture, continuous-flow solution culture and aeroponics. The medium culture method has a solid medium for the roots and is named for the type of medium, e.g., sand culture, gravel culture, or rockwool culture.
There are two main variations for each medium, sub-irrigation and top irrigation. For all techniques, most hydroponic reservoirs are now built of plastic, but other materials have been used including concrete, glass, metal, vegetable solids, and wood. The containers should exclude light to prevent algae growth in the nutrient solution.

1. Flush plants every weeks with a fresh water
ReplyDelete2. First watering should be when the lights first come on (morning).
3.. Last watering should be 1-1/2 hours before the lights shut off (most mediums).
4. Change your nutrients every 7-10 days.
5. Always pour your nutrients in your reservoir one at a time so they mix slowly.
6. Always keep an air bubbler and air stone in your reservoir for oxygen and nutrient mixing.
7.. The following meters measure your nutrients/food levels. THIS METER IS A MUST. PPM (Parts Per Million) , TDS (Total Dissolved Solids) , EC (Electro Conductivity)
8. Store all your nutrients in a cool and dark place.
