I have been looking around for some information concerning the recycling of fertilizers. I know that growers change the res in small scale ops but i have heard of lettuce farms who keep the fertilizers indefinitely. i can avoid the use of sulfates and chlorides and use RO filters to keep useless salts from building up to toxic levels. I can right now feed plants chemicals which they will use up entirely, but is that enough? Because I have heard that plants themselves release chemicals into the water, is that true? if so, how is it recycled? i can in fact use a tester for every element in the water like nitrate tester, phosphate, potassium, calcium, magnesium, iron, etc... each can be tested alone and then TDS test to know the useless salts' concentration. this of course is not for small ops, and is not for marijuana farming, i am in the process of studying a project to grow hydro veggies, and i have a very busy test greenhouse on my roof. Anyone knows where i can get info on commercial hydro methods?
