I am in the process of planning out a 5'w x 3'd Hydro grow closet. I am planning on growing autoflower under LED lights. i am trying to find out what the most space efficant Hydro sytem is?
The most space efficient is certainly DWC as it's just a reservoir with the plants sitting in it. It takes up no more room than soil grows really. A low profile reservoir like this saves some height
Hempy buckets are the easiest hydro. I'm using 100% perlite in 3.5 gallon Rubbermaid-type waste baskets. Working great. This is my first grow.
