i recently bought 2 150 watt cfls with ballasts the bulbs are 5000kelvin. i thought they might work well to start outdoor plants this year. im going to stick with my 400 mh after trying them. but im going to build a box and try a scrog with them. my problem is im having trouble finding lower kelvin bulbs for the cfls like 3500k maybe. i have no expierience with cfls my local hydro stores dont get into them and searching on the net is how i found the 5000kelvins. but nothing lower.
