Hello, so I have a 400 watt mh running under my 5 day old sprouts, I do not know how far I should put them, I have an air-cooled hood, that's being vented, and a fan pointed at the glass front of the hood. Even if I put my hand against the glass it's just slightly warm, should I put my plants super close as if they were floros?

Once I put an enclosed reflector (CoolTube6) on my hps 400w it made a huge difference on temps. I let my plants get a few inches away. I just watch them to see if they don't like to be too close or whatever.

I'd put it about 16" above the plants and let'em grow to the light.

If they are closer to the light will they grow faster? Reason I ask is because I only have enough time to veg for 3 weeks total, and it has been 5 days already

Depending on the plant. I've had some be ready in 3 weeks from a seed. But I've also had some take 6 weeks from seed.

Seems like at 3 weeks from seed is when they just take off from seedling into veg, this is when they have rapid growth " at 3 weeks" but ya gotta do what ya gotta do...............

if you got good cooling you can go from 8"-12" ..they stay waaaay cooler than a 600 does.

Yea 3 weeks from seed, but 2 of 3 seeds germed in 12 hrs the third took 36. Then those two sprouted in about 12 hours too, then the third took about 2 And a half days...
