1st Grow! - temp/humid for dome cloner?

Hello! This is my first grow since attending an Oaksterdam course last year~
Im using:
-4 foot T5 light with 8 bulbs 6500k for clone/veg room.
-heat mat
-4x4 jarden tent
-2 fans, both 250cfm (1 intake with air filter on outside / 1 exhaust with carbon filter on outside)
-cloner dome

Controlling the intake/exhaust fans I can keep the tent anywhere between 73-79 degrees.
Suggested to keep light 12" from top of clones...well its more like 3'+ in the picture because the temperature inside the humid dome is 85 humidity 60%.



Question 1: Is this temp too high for these seedlings to sprout?
Question 2: Any suggestions on lowering temperature in these cloner dome things?

My cat just had to take this opportunity to check out what i'm doing!

Are you trying ti germinate seeds in rockwool inside there? You don't need the light at all to do that. Low 80's work for me to germ, how long have they been in there?

Started them in paper towel, taproot were about 1/4"-1/2" long so I placed them into moist rockwool and covered them, placed them in the dome and turned the lights on 24/7 until sprout out!

Sound good? Been under light for 7 hours. Temp: 80.5 humid: 40%
