the space your workin with will work but your not gonna have anything monsertous. they are going to be small plants. id say go with some high output t5 lighting for your space they are cooler than an hps, and seem to work better in smaller places heres a link to look at some but there are other places with diff price so check em out. hope this helps.
u dont think it is possible to come out with good bud. growing with a 150watt hps. in the space given. also how many plants can i grow on a 1500wat hps.
probably around a 10'by 10' area with the 1500 , and i just think that you will getter better results off a t5 than a 150w hps. 400 watt will do about 4 plants so use that as a guideline
