A tight squeeze! Light help!

I'd upgrade from that amp. Include your light source and container, you'll be looking at a cool 2 inches of height to grow a plant.

wait, why do i have to start at 2700 and 12/12

because your box is less than 2 ft. if you have non-autoflower you have to flower it immediately(from seed) or it will out grow that box. go to a garage sell or something and get a pair of only wooden box speakers or something. But if you do decide to grow in that id grow an auto flower in a teacup with a cfl. The cfl needs to be 27k since your flowering at the start otherwise youll have to find a bigger box which defeats the purpose of growing in your easy bake oven there your makin good luckman
