Due to the fact that you canât adjust/dim the 100 watt light I would leave it at 36 in. If you notice legginess then move itâŚ
I would use that light through seedling. Once you transplant switch it over to your regular lights with your manufacturers requested strength and height.
How did you decide when to remove the domes? Mine are still in place after 4 days now. The seedlings arenât spread out much, but they are getting pretty close to touching the top.
Keep in mind if your RH in the tent is not in check then you use the domes for sure. As long as youâre RH is fine in the tent the domes arenât required after about an inch.
Rh and temps should be up to par during seedling stage if ever you needed it to!
I personally like 75° - 80° and 75% - 80% RH until veg.
Also, on your last one thatâs still under the done do a test. Leave it under the dump until it reaches the top of the dome and compare the growth
Iâve cut bottles in half, used cupcake clam shell containers, and whatever it takes to make a dome. Proper temperature in relative humidity is the key. The domes are utilized when your environment is subject to difficult controlling. They fill the void by adding the protected trapped moisture in an enclosed area providing better relative humidity.
I use domes a lot at first when I had issues controlling my environment. Once I was able to come to the realization the only way to control your environment is to spend money on equipment that will allow you to do so.
So yes, domes are majorly important when youâre not on point in the tent
