Currently I am using soil and in the middle of a crop, which is going fairly well. Id like to try hydro with my next crop. I have looked around and learned about many different passive and active systems. I understand that active requires pumps and seems a bit more advanced. Passive sounds a bit more my skill level with setups like Wick Systems and Gravity feeds. I am kinda on a budget, but thats why im thinking ahead. For a beginner whats a nice hydro setup?
Read A Hempy adventure.... by a guy called _numb_ .He has a great how to using the Hempy Buckets, which is a passive hydro system. I just used this method, and it's easy, yet productive. Good Luck!
