personally, I wouldn't be wasting total 800 watts of metal halide on seedlings ... just hang a cheap CFL or flourescent tube, about 1" over their tops, save money, and wont be throwing all that heat, either ... :smokin:

What he says.the postman.
so yea i think i might actually go get a floro, one of the cheap ones and do that, but since im going to do that, how long do i keep um under the floro before moving to the mh? like maybe when its got its 5 node or what? thx again guys
I have a loose rule of thumb on when to transplant or move seedlings or clones under larger light (I do both the move and transplant at the same time): When in doubt, wait till you see bits of root start to wander out the holes in the bottom of those little pots you're using. Then you know you have a good, viable root ball. You can probably do it sooner, but good roots are the basis of a good plant, so personally, I'm not in that big a hurry.
I agree with the folks voting for less light. For the first few nodes, gentle light, gentle everything is better. I get those little 18" and 25" full-spectrum gro sticks. They're cheap, self contained, cool (10w/ft), mount anywhere, and don't draw any attention. They last about two years. I just bought one today to replace one that gave up at about exactly 25 months.
