thats funny, my kinda grower

so mac you think i veg, fit 100 clones in dixie cups for month under a procyon? -phatsesh101

Well imho a procyon does a great job at 2'x2' but might cover up to a little more. How big in diameter are your dixie cups? Do some math and figure it, or if you have the cups, lay them out as an engineering model and measure it.
I used 2 mounted side by side on a light rail and covered 3'x5' over moms (kept abt 2-3' tall) and seedlings and/or rooted clones on raised shelfs to keep all the top hieghts the same. The lightrail changes the angle of attack of the light, shading and unshading parts of the plant. It helps with the penertration issue.
