hmmm if heat is a issue ill jus do it in my closet ill jus use a box to block out the corner into a small grow space and use some reflective shit like mylar so the light wont shine out solves height problems and if i put it in my closet keeping it cool with cfls would be easy is it cheap to run them? also latewood pretty much said its not a bad idea i dont think so either cuz the water would help keep it cool and it wouldnt need to be a a big bicket jus wide enough
