That sounds good bro, i have a fan on them, not the little seedlings and true the fan does dry out the soil, the wood stove below, the chimney is heats their chamber, is pretty awesome, i was showing my brothers the cool set up you got.Also I'm using a fan in the cabinet, that helps to make them stronger but makes it too dry so I use wet towels to keep up the humidity. Woodstove heated cabin is always very arid.
