could u point out the dark side of runing multible H.I.D. lamps cuz in another 5min im gona be riping out weeks of work and doing a totaly revamp. mylar the works. i emagion air cooling more than one hps light would be vary diffacult but if u used increasingly larger duck sizes as i went from light to light wouldent that reduce the total resistance. i cant see that lil fucking 150 runing cooler than my air hood, even in the dead of winter the whole hood is made of plexie glass and holds heat quite well. it would give me 10 diffrent points of penatration from all sides but below. i am aware that i am stuck with a 3 foot plant and i did this intentionaly to force my self to keep one nice traditional looking plant with one large cola. advice on training such a large nicely shaped tree with out losing that main bud?
