I have it almost touching the plant. I see difference in the plants idk. What the stain is its bag seeds I'm trying this out bfor I buy some good seeds can yall tell me were to get some good seeds I was looking at dutchWhat is the wattage on that 6500k bulb? Is it cfl? If it is it needs to be nearly touching the plant unless its 130w true wattage or greater. Then it needs to be at about 12 inches. If it is a normal household cfl you need a few and very close
