Gen Reviewed by Gen on . reservoir water level question ! I'm setting up a closet grow system with 5 gallon buckets and I'm using 6" pots suspended through the lid of each bucket. I plan on using floral foam for root support. How far up inside the bucket should the water/nutes be with the pots installed? :rasta: Rating: 5
