Iv ran out of room in my small indoor greenhouse along with wanting to upgrade my lights to LED. I have learned the shelves in my greenhouse aren't far enough apart to use the LED I want. So time for an upgrade but research first. I was wandering from all you that use grow tents how you balins ventilation with humidity. Do you put the fan on a timer so it comes on for certain periods during the day and then let the humidity build up nately?. Or is the fan on all the time and in that case how do you keep the humidity up? I was thinking of using the fan that goes right in the vent tube on the top.
