My friend has little seedlings that just sprouted. They were under a humidity dome previously at 95% humidity. Once he took the dome off the humidity dropped to 20%...

My question is how to get higher humidity levels? I read that the humidity dome must come off once seeds sprout. So how can I get higher humidity levels without a humidifier?

you can pour water all around the grow room floor and let it evaporate,or you can buy a humidifier for 20 at wall mart

I tried putting more water in the tray, doesnt seem to help though.

Im also curious how far should my 105w cfl be from the plants? Their maybe 1" tall now.

I have the same prob. rh is 25-30% with a humdifier and bucket in grow room. I don't know what to do. Will RH this low really effect plants and if so how?
