i have a 21" wide by 4ft tall cab i made. will 10 26 watt(6500k) cfls (16000 lumens)be enough light for 4 plants in 3gal square buckets im using ffof for soil and how many (2600k) will i need to flower for that space sorry no pics...and is this the best soil i can buy?
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).

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!
