only have 2 MH 600 watt....

ive just germinated some seed and im about to pot them....

isnt this light too powerful?

wont it burn or cause them to stretch any ideas?

I did the same thing on my current grow because I gave all my fluoros away. It's working great, never had seedlings grow so fast. Just make sure the light is far enough away so the plants don't get burned, I have about four feet between plants and light, no stretching at all.
