i would go with a simple soil setup
your soil should consist of potting soil and perlite and maybe kiln dried or masonary sand
for nutes i would go with canna terra www.canna.com
and lights go with an envirolite blue spectrum for vegging and an red spectrum for flowering
these lights will be perfect for your growspace as they dont give off much heat and are self ballasted
get an indica strain as these are more suited for small spaces lowryder are perfect for small spaces
if you are gonna try a normal indica strain veg it up to half the hieght of ya grow space or 1 foot which eva is best for you on an 18/6 light cycle ,
when ya seed sprouts i would give it just plain water for the first 3 to 4 weeks then start adding nutes after that
use mylar for on the walls for added reflectivity and get some type of ventilation and airflow in there
hope this helps
cheers all
