How is this light setup?



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?

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.
 
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.
