Its a 400w HPS setup with the ballast turned down to 250w, got the light a good distance from the plants, which were planted on the 7th after successful germ and finally sprouted a few days ago. Should they go back under the CFL for another week or so?

Your plants are going to stretch my friend.

Why exactly is that, to much light? Should they go back under the 4 T5 40w CFLs for now?

Ya why do you say they will stretch ? His temps are in the low 80s and his light looks like it is only a foot or so from the plants!

Light is a good bit taller than a foot from the plants. The lower I bring the light the higher my temps get. Not sure what the ideal temp is, but I dont feel it should be 85*+

I had it a bit lower last night to mess around, and sometime over the night/morning it got to a max of 90* on the board according to my thermometer.

if you ran a mini fan you could lower it closer to the plants.

I Just lowered the light to around 20in off the top of the plants and turned the ballast up to the full 400w. Temps didnt seem to rise. I have to go to work for a bit, would it be a good idea to leave it like this knowing the temps could rise up to 90 again, or should I turn the ballast back down and lift it back up a good bit?

I hope you didn't lower them too much. Keep an eye on your babies; they can die in minutes from too much light. Seriously, it's called "hardening off"; you want to expose them gradually to more and more light. Good luck.

I lowered it probally 10in lower than it was before, I grabbed a fan and put it in there, dropped the temp roughly 4*. Staying at 78-80ish now.
