is money an issue? if not i would recommend:
4x pots (ideally 7litre or larger)
4x saucers for drainage
1x light (250w HPS would do nicely but the more light the better) however, more light = more heat, so you may need 1x cool tube and 1x extraction fan
1x carbon filter
1x ph meter
1x hygrometer
1x grow type nutrient ie. Plagron alga grow
1x bloom type nutrient ie. Plagron alga bloom
get on youtube, search something like 'closet lowryder grow' and watch the vids, read the comments. take in all the info and the different set-ups and decide what is best for your grow
good luck dude hope thishelped
