Yep ive started plants with color temps and wattage in that range. 6500 would be optimal but if your switching to an hps in the future, the 32w should give u a fine start]Just picked up 4(32watt 4100k color temp)bulbs to start my seeds off. Im growing 8 plants. Im only using this to start them up then switching to hps. Will 4100k color temp work? Has anyone had any luck with this?
