truth is, my grow is actually 29.5" tall... i have an easy 8-10 inches left above the lights now... i would say it was wasted space except it lets the heat have a big area to rise up to... with 600 watts the top of my grow tank is well over 110 degrees F (need a bigger exhaust fan now) but at canopy level it is only 83 degrees.
the reason i get away with such a short grow is i use a ScrOG... the buds cant get tall cause i tie em down
that said, i still pull 14" colaS off my plants. not too shabby.
