Seedlings need high humidity (Over 40%) - and can take up to 90 Degrees.
Whats most important is the temp of the media you are growing them in. If the room temp is less
than 80 degrees, get a seed heating mat from your local garden storeto place under them.
Great ! You may want to get that under 40% when you start flowering, check it when you have the lights
and a couple of fans are blowing in there - if its still too humid, either get a dehumidifier from lowes or
wallymart.
