phatsesh101 Reviewed by phatsesh101 on . Quick Question I just finished building my grow room and all I need are lights.. I want to use HPS bulbs.. If I plan on having around 10-15 plans.. What wattage bulbs and how many do you think I would need? Also could you please post a good link to a reliable, affordable site on the net? I've been reading on here for a few hours and most of my questions were answered but I just want to make sure.. Thanks for you time, Tyler Rating: 5
