When I'm lacking motivation or feeling lazy I'm going to visit your thread to kick my ass back into shape!
LOL, I just thew away a bunch of 4" tubes that I had arranged in a stadium style grow, recently just switched to all trays. Hope these work out well for you, I'm sure the 6" ones have a bit more space in em.
It is fun to see the progress so fast, got to make you feel good to have come so far!
Alright, lets see a canopy shot!
Good luck, peace
When I was starting the thread, I had thought about naming it the, "Laboratory Grade, Half a Hundred Thousand MMJ Facility" thread. Seriously though, THAT thread made me randy. Half a million??? With all of those beautiful white trays, and rows of 1000 watters as far as the eye can see. I'd assume that trays have their own set of difficulties, but they do look nice and easy to run.
Tubes on chains are great if you're rust-cursed with less space than you had planned for.
