Ugh, I forgot, I have more to say! And apologies to Killer, as this is his grow, not Bozo's as I mistyped before.

Instead of your highly flammable paper box, maybe try setting up a small PVC frame of the dimensions you require, then wrap it in mylar emergency blankets. It isn't light-proof, and neither is your current, but it works well and looks neat when all closed up. You see a dimmed version of your garden that you don't have to squint at!

When 12/12 comes around you'll need to think of something a bit more complicated. Probably start scheming now, if I were you.

edit: One last thing, maybe get rid of a few of those just to keep things on a smaller scale? Personally I would do 5 or 6 and hope for half females. After that's established, mom it up and clone your ass off
