aye it will b small what kind lights should i get and how much will they cost
as many CFL (compact flourescent lights) as u can afford AND at the highest wattage u can get. Now remember with CFL lighting, u have to really watch the wording & read the package, because they will say something like 100watt, but really when u look closer then r only light 9 watt which they say is EQUIVALENT to a 100 watt standard bulb. I understand wanting to get on "the cheap" nothing wrong with that, but to produce the MOST bud & the better tighter bud, not loose shit, u r going to have to invest a little more. ANY more light (CFL) is better then none. Remember if u can only afford one, better to get a true 65 watt CFL bulb, then 10 CFL's that r only 9 watts each. If u can afford a few, which you can literally place on top & even to the sides if u want, get a few like 26 watts in the 2700k range since u r in flower.
sry...saw u asked about price probably about $10 for the 26w, maybe $15 for the 65w, just a gestimate of my memory... don't use CFL except for seedling, & then it is a 54w T5 tube lighting.
