@RedEyedRenegade,
Light Closest~ Sunlight Furthest
150W 8" (20cm) 10" (25cm) 12" (30cm)
250W 10" (25cm) 12" (30cm) 14" (35cm)
400W 12" (30cm) 14" (35cm) 19" (48cm)
600W 14" (35cm) 16" (41cm) 25" (64cm)
1000W 16" (41cm) 22" (55cm) 31" (79cm)
But keep it 50cm away from the plants till 2 or 3 sets of leaves are there to take all that light in! Regardless of heat,lightburn is always an issue with HID.Not on here yet but been using 600w MH/HPS setup 2 years now and learned that the hard way early on..
You can always bury a bit from the stem when you transplant,given that it is hard enough,it will just grow roots when covered and lightly watered around it.
