First grow...Bit of help please

Ok ive decided to going to do a grow of dieselryder. The setup is gonna be in a chest of drawers with some DIY mods to it.
The drawer is already halfed so each side is
30in high, 20.5in wide and 14in deep

I could take out the piece halfing it but i think ill leave it because its gonna be useful when im not using lowryder seeds when i wanna seperate my plants for growing and blooming.

Still cant decide what type of hydro system to use. Any suggestions....probaly on the easiest to use with best results.

Would this an Sonlight AGRO 400W bulb be suitable??

Cheers.

wood holds heat - watch out for it being really dry in there (i.e. no humidity).

i have a random question...i have grown outdoors several times with good results. I'm now trying hydro drip system and i'm concered about 3/4 of my plants. They are a darker green (which i'm not worried about) but they have a rough leathery feel to them and look slightly wrinkled. The strains are snow white and supergirl by nirvana seed co. The ones that are ok are big bud by sensi seed bank. i'm unsure if it's the seed co. or the nutrients. i almost think its an iron deficeincy, but im giving them cal/mag which has iron in the formula. Has anyone encountered this problem?
