Indoor growing help

Okay, I have a box, which is h 2', w 2' and l 4-5'.

Inside that box, I shall grow 'lowrider' marijuana, anyway, i was wondering, what nutrients should I use?

Also, 18 hours of light a day sufficient?

As for potting, rockwool within topsoil alright?

I'm new to this game, so any help would be appreciated, also, I only expect to grow enough for personal use.

Many thanks

are you saying that your total grow space is only 2 feet high? because thats way too low. or are you saying that you have a "planter" that size; like a rectangular pot? if so, make sure to put each plant in separate pots so you can remove the males easil0y. how many plants are you growing? and what kind of lights? as for the nutes; foxfarm or advanced nutrients are good i hear. 18 hours of light a day is perfect for vegging, but switch to 12 for flowering.

in the beginning use either 24/0 or 18/6 light cycle....24 hours of light and 0 hours darkness or 18 hours of light and 6 hours of dark...i recently changed to 18/6 myself so if that what u been doing stick with it!!! dont use nutes for a couple weeks until at least 4 inches or more...if grow area is 2 feet high you gonna have to flower early on and still not sure if you flower early if 2 feet be enough room...probably can be enough space if you can figure out how to make it work

wow, thanks

To clarify, lowrider's onlyu grow to 30cm's high, so 2 feet of space is sufficient, there is aslo no 'vegetative' state'

Ant idea's on nutrition?

no 'vegetative state'?

I would use as many hours as possible for lowriders to get as much out of it as you can, even 24 a day if you can. I use foxfarms with very nice results.
Peace

Thanks guys
