I don't follow the common advice of starting seeds in towels or napkins in the dark. Mine go straight into rock wool cubes and under a t5 placed about 18 inches from them. Raise humidity and let go until they pop. After the first shoots start to show, after coteldons appear. Light gets put closer, just above the dome of humidity tent. T5 doesn't run hot at all. I'll let them grow into the light, even touching it until all seeds are about the same height. Kind of a forced technique maybe? I also run veg lights 24/7 until they get moved to flower. Good luck. You'll be successful! Take your time, be patient and eat a hearty breakfast.
