Well I have some free space opening up and some extra equipment sitting around. Im trying to get the most out of the space and I love trying new things so and I have never done vertical be for.

I Have a 24 site ebb & grow system not being used and Im thinking of using in my new space the room is going to be around 8x8 or something like that I can build to fit what I need. Im thinking of using 4 600 watters scattered around the room Im just not sure on how Im gonna do this yet. Would it be better to stack the 2 600s and use cool tubes and circle 12 plants around each set of light or would it work better to hang them solo naked bulbs around the room?
Im gonna have to do this with no a/c. Im in a 1500 sqft room with the grow room built inside that. Im gonna keep the ambient air temp in the main room at like 50f-55f and use passive air intake and exhaust thru proper fan and filter to exhaust the heat.
Again I can build the room to what ever size I need so if 5x10 would work better thats what Im gonna do.
I could easily drop a couple 1ks in magnum xxxl hoods over them but I want to maximize my grow. This room is going to be competing against 3 1ks over 12xl under current system. So we can all see the difference in yield from 4 600s vertical vs 3 1ks in hoods.

If anybody could shine some light it would be greatly appreciated and the knowledge would be put to good use.
Thanks for the time BigGreen

just one point to offer you - cool tubes are not required for two x 600w HPS stacked one on top of the other.

Floor fan underneath the bottom bulb, column of air going up. Put a cage around the bulbs to keep the plants off of them.

Don't cool tubes cost photons? Please correct if I'm wrong about that.

I under stand that I just wanna make sure I can cool the room with out an a/c. If I can do it like that then thats what Im gonna do I think it might be just to hot with out the tubes.
Thanks LJB

I am idiot sometimes and don't read carefully before replying. Thanks for the wake up call!

[BigGreen]

No I wouldnt say an idiot probably just a pot head like the rest of us on here. No problem any in put is thought out thanks.

Does anybody else have any pointers or advise anything is helpful I need to start planing the build out and the toy list in the next 2 days. There will be a pretty narly thread starting after the room is up and running 3k 12xl uc vs 4 600s vertical so please lend some wisdom I really pumped to get the ball rollin

I'd say go with the cool tubes since you wont be running any a/c. I'd still use the fan below the tube idea though, and venting properly from the 55f ambient air in the enclosing room. I've been thinking about turning my 3.5 x 5 closet into a vertical set up and use the 2 600w (hps/mh conversion) in there with 2 gals.

Bump
Thanks solarz for the aadvise.

Im still wondering what gonna be the best way to do this. Anybody ? Im just in debate about just hanging 4 bare bulbs in between roughly 4 plants and get a big ass fan for exhaust or stack the 600s and use the cool tubes with roughly 12 plants around both lights.
It would be nice to here from a couple different people that have done either one of these styles so may be I can look at the pros and cons of each style.

Thanks for any help greatly appreciated

What no love for a reflector grower trying to learn this big amazing vertical thing. I know its the shit but I just like getting shit right the first time and not waste any $ on stuff I might just throw in the corner later (like reflectors) if it works out.

I'm running a tent with one vertical 600W along with a 400W horizontal.
The 600W is in a cool tube, it's essential for me to run the cool tube since heat build up would be a killer without it..
I'm building racks for the next round but here how mine looks atm.

[BigGreen]

So that fan and filter cool the 400 and the 600? Whats the temp outside the tent and in the tent?
Thanks for the reply mrb
