Just make sure you have a handle on the heat/RH in the tent, have you done a "dry run" in the tent?
You know, like running your time clock, checking of ambient temps and RH...
You need base line stats, so if something goes 'haywire' you'll know why...
Keep light at least 2 feet away while the seedlings are under 3-4" tall... Why because until then, there roots are too small, and plant would be subject to heat issues...
Check your temps at the top of your plants, not on the shelve or where ever the gauge is...
Good Luck man!
