I suppose it might work if you ventilate it with a couple PC fans...But you cant just ventilate with a few holes. You have to put one sucking air IN and one blowing the air OUT..So make a lid that can hold the fans in at the top then put one of the fans pointing in and the other pointing out.

The tin foil will deflect any light and create hotspots..Which is bad for your plants. Use Mylar.
