[h=1]Dual 250W 2700/6500 Kelvin CFL[/h]
Any ideas?? My grow box is this it's basically a big clothes trunk with the bottom shelf taken out. has opening doors for ventilation.

Let me know guys, thanks

Looks happy now. I would say just the one. When you flip it's going to get twice as big so careful.

As long as the heat can be kept under control the more light the better. I'm not sure your demensions on your cab but they will stretch when you flip. Can be up to 250% on some sativa strains.

unfortunately you will probably get way more PAR by hanging the light sideways. CFL's have a notorious deadspot hanging like that. I had to re-do an entire cabinet because I wired all my fixtures to hang like this. Lesson learned. I even resisted for months after being warned.

no flipping required on this one... she is a Vertigo Autoflower from Paradise Seeds (on the recommended 24/0 from seed). And unless this plant's yield will be under 20g's I plan to continue learning to properly grow autoflowers for now...
