hydrohut macgyver needed

So, I just got a mini hydrohut. Can someone tell me how to make something to circulate the air. It gets pretty hot. I plan on buying a reflector with duct holes later. but for now i want to build something to exchange the air inside and cool it down. (see pic)

Any ideas?

the hut should haeve pre fabd hole for a 4in exaust fan.

Would it be a problem to leave the door open until you were able to put together the proper ventilation? With just those two fans and the door closed temps will still be very high. I did a test on mine the other day with no vent(and nothing in it) zipped her all up MH400w and walked away for a few. Came back unzipped looked through and temp read 121 deg F!!!!!! Only a a box fan might do if you could fit it in there??? Your best bet is to put together your exaughst as soon as your able. Thats wut im in the middle of Vortex 6"..... a lil over kill but alot of hot air is cleaned and removed from my room with just the scrubber.

you need to hook up an exhaust fan to one of the pre-fab holes in there to create a passive airflow. you will most likely be fighting a losing battle until you get an air cooled reflector though.
