new closet grower, help needed.. pics and a few doubts

so if started for a week now and 3/5 sprouted (till now i had only my 2 cfls on now that i turned on the hps the closet is hot as fuck!!! nearly 35ºC = +/-90ºF) i'm going to need a co2 system for them to support so much heat right? im going to have to struggle against the heat

But first, should i remove the plastic for the ones who have germinated and put them into their growing medium? (soil)

also the digital therm. wasnt recording the temps right, is it cause its directly under the light?

the co2 won't help the heat issue as much as you think; you ought to buy a good fan and probably a cooled hood for your light.

Yeh man! Get those ladies into soil! Keep your temp reader out of direct light, readings can change depending on its location in the grow room/tent.
Enjoy!

Cooltube or Air-cooled tube, and exhaust your heat to a different room.
