Floater screens keep me mobile if I need it. 8 plants in the 4x8 flower tent and all have floaters. One single plant finishing up in there..Romulan...but it'll be done soon.
Floaters give me the mobility I need sometimes growing multiple strains and the benefits of the scrog method. Last grow I let things get a lil wild with no floaters. Made me crazy..really. Now I'm back in control and feel much better about the grow.
