Nice man, I dont know a lot about hydro, but it sounds like your doing good man. I move into my new place next week. I built my exhuast ventilation system yesterday. Had to make it silenced, so it wont bother the neighbors. Since I went ahead and went with my 6" ventech inline fan that is noisy like a jet engine lol. Imuh make a journal in a minute.
Keep us posted man. =) I want to grow some sour crack eventually. what did it smell like last time?
