just thought I would mention...1st time grow...money issues...I have 2 ladies that are 3 and a 1/2 weeks into flowering here... crystals/budding galore. I am using 2 lights & reflectors from a pet shop( bulbs $8.00 each, reflectors $10.00 each). The bulbs are 150 watt reptile basking lights. I supplement the lights with compact fluorecents to the sides of the plants...In the long run I wanna change to a more conventional light sourse, but I gotta say for the cash these lights are not that bad...peace
