Sprouts & Temps Question

[dmeyer07]

Alright guys i've started my first grow, 8 seeds (bagseed). They are off to a pretty good start i think, they've all germinated and are about 3 inches tall with 4 leafs, and are about 3 days old.. I have about 400 watts of 6500k 4' fluro's.. My problem is my temperature! I have intake vent and an exhuast fan as well as a fan blowing over the lights and a humidifer to keep humiditiy up there.. My temps are raning from 78 to 84! Is 84 too high for a sprout? Will it drasatically slow growth down or do i just need to keep an eye on the soil drying out quicker.. I have a c02 setup but i've read it will do little for them at this age so i haven't started using it yet...

Should i maybe take some of the bulbs out to keep temps down a bit?

What do you suggest, and whats the highest lowest i want to go temp wise for these lil girls...

Thanks

84 should be fine for the little ones. Might want to get a fan pointed on them to help keep the temp down a couple degrees and promote stem strength. Just be sure to keep those flouros close, and don't let the soil dry out too much. Having the humidifier should help with that. If you could keep the temps around 75-78 degrees at the top of the plants, with the lights on 24/7, you will be in good shape.......

your temps. are fine. stay away from the ends of the tubes. that's where you'll pick up heat. airflow is important and will help keep temps. down. a "gentle" breeze is all you need. no hurricane force winds.
