...yeah man, i'm a lazy old phuck so i wouldn't want to spend all that time SCROGing and if you have an oversized fan like my 8" Vortex S-line which is rated at more than 700cfm's and a couple of circulation fans, one directly under the dangling bulb and one or two blowing down on the plants, there's no reason you can't run barebulb vertical, it actually simplify's cooling and, as you can see in my pics above, there is no ducting to get in the way and take up real estate.
...if you have a 5,000 btu window AC unit in a spare bedroom you should easily be able to run a 5 x 5 with fluoro's for your entire veg op and a pair of 4 x 4's on a flip-flop running stacked 400's in each, barebulb vertical style, ...so 800watts of flowering HPS running 24/7, so long as you have the space to fit all three tents, you might look for a spare bedroom with a walkin closet large enough for the veg op or one of the flowering ops, ...either way, set up like this the spare bedroom becomes a kind of lung room that is filled with the cool air from the AC and that cool air is then passively sucked into all 3 spaces and then exhausted back into that very same room.
...there are certainly better ways to set up but if you are on a budget and can't afford to do it pro-style, this can easily be made to work and cooling your barebulbs would be no big whoop.
...on an 8 week cycle with you harvesting either both tents at once or one per month that should easily translate, with a little dialing in, to at least an elbow per month, consistently, month after month, so long as you keep the veg and cloning op running smoothly, you wouldn't need many clones but you'd need them regular if you wanted to run a perpetual setup.
peace, bozo
