is this a 3 dimensional cabinet?

if it's 21" x 21" then 21/12" = 1.75 x 2 = 3.5 x 5000 = 17500 lumens

or in english you have 3.5 sq ft. you want a minimum of 5000 lumens per. so you'll want 17500 lumens, or about 11 bulbs. those are gonna run at *1600* lumens, not 16,000!

you'll want at least the same of *2700*K bulbs for flower. the more the better!

you'll be able to grow some nice plants.

i can't speak on the fox farm soil, as i have never used it. i'm sure it will do fine. i use miracle grow and don't have problems. more money doesn't always need more better.

make sure you have a way to test yoru pH. that is way more important than what type of soil you buy (for the most part).

AHHHHH I searched everywhere for the equation and couldn't find it so I gave up!! LoL glad you answered cause I couldn't!

P.S. 5000 Lumens per is for optimal growth, I think it's 3000 that is the minimum, but I could be wrong.....

no worries italiano! it you have inches, divide by 12. multiply length times width = sq feet.
and remember 5000 lumens per. and that's all you have to remember. lol!
