upper left hand a little fan for a computer you can see. if you zoom into the bottom, you can see the plants are on a rack over a reservoir where the fog rises up to the bottom of the pots
also have a room fan blowing over the top to cool it d0wn from the LED grow lights all around it. humidity comes from the exo terra foggers from PetSmart. the masdies come from Hausermanns online stock. well grown and bug free.
its working for them so far .. both thumbs crossed
