I don't think they have an air cooled vertical lamp...And also air flow should not be a problem since i got intake and outtake fans with a combined cfm of 480 as well as a 12" oscilating fan....I just think that with all the leaves the light will get blocked and won't reach the bottom half or somthing...i really don't know as this is my first time growing...add another 1000, hang them vertical, then go for it. plaster the walls with weed. literally.
good idea...If you do pack the room only the canopy gets the light, So to increase density in your top buds shave your bottom branch's right off. Then air can circulate under and over your canopy. Just like a blanket of sticky bud's!!
your set up in the pics are exactly like mine...except mine is in a square of six by sixI have a bach under my stair's in a similar set up. Im going to do just that with them. {blanket o bud}. pic in my gallery.
