Hey guys. I'm new here, and ive been looking and ding some research on this site the past week or so and figured i'd give my first post. I'm not very good on using forums much suchs as posting etc.. But Ive finally decided after awhile that i'm going to do an indoor grow in a closet with DWC. Im making it myself in a tote. So one of the questions i have is. I'm going to be using a 3 inch net pot. How far do i fill my water levels up to? And another is what are the best nutrients to buy ? and i can't find a lot on nutrients.. I know nothing. I don't know what each kind is.. Anything will be helpful and hopfully this post is alright. lol
