I found myself in the same situation years ago. What we did was get a 30 gal trash can (don't know how much herb you're talking about trying to dry) and drill 1" holes around the can, about 3" from the top. We cut a hole in the top and put a 100w drop light in it. Occasionally, we would take the top off and turn the buds. After letting them air out a half hour or so, we put the top back on and repeated the cycle until we had the desired result. We dried multiple #'s with no ill effects.
