will they be fine until i get a new light?

OK, so I popped 15 seeds this monday and they're all doing great. My only problem is that my Reflector is too big to move on a Light mover and I can't use the full space. I'm ordering a Medium sized adjust a wing today to get it here by next week.

Now, my question is will they be fine under just one 600watt MH light for a week or two until I can get the second reflector, or will they need more light?

I figured since they're all still just barely getting out of the soil and showing cotyledons that they don't need enormous amounts of light because they only have a few very very tiny leaves with not enough cells to absorb all the light.

they will be fine as long as you are controling the temps

^ what they said. I've put 10 seedlings under 4 23W CFL's til they are 2-3 weeks old and they were fine so you're good bro. I just use that 4 gallon container and rock wool, so that's less than 100 W and they were fine so you def should be good with a 600.
