I am working on a 12' x 14' x 36" nightmare crawl space.

I have 6 4" 10' pipes with 3" holes and pots , 8 per pipe. Feed is simple 3/4" pipe to 6 reduced to 1/2" and one line spagetti hose per pot(2 eventually). Drain to this point is 2 small 2'x4' tables at the end of pipes joined together.

Does anyone know of anyone that has done 6+ bulbs in crawl with pics/details?

This is by far the hardeest work area ive ever setup and would be great to see one,, to keep me going.

I was going to run the lights in the joists with small batwing shades but they really heated up the floorr above. I now have one running vertical no shade but its pretty close to the pipes and dont like the heat. Cool tubes would be the answer i think but am gettin strapped for cash and dont want to spend 800bucks.

Im trying to find my camera for some pictures and will update as i go.

Im sure this will be popular since i have surfed the net for a month steady with absolutely no result except for cfl's.

Dirk,

Big props for being creative and having the nuts to try something new. But, fuck, bro. Can you make this work with your height? I just can't see how you're gonna pull it off. If that's a 1000 watt light, you'll need to keep the plants at least 24" from it. I was thinking some kind of vertical side lighting settup...but you don't have the room to stack up the plants. I'm really sorry man. I've looked at your pics for an hour racking my brain, but am coming up short. I've built dozens of ops, and have a can do attitude. I just don't see it.

The only possible alternative that I see is to use T'5's, lower your tubes to the ground, and grow very short plants at a very high planting density. With T-5's your plants can grow right up to the tubes. The heat won't be a problem. You'd have to bloom the plants as soon as they rooted. Start wrapping your head around the fact that you just don't have the space to run HID lighting. You're also going to have to lower those pipes. Dig a fucking hole for the resevoirs. If you used T-5's, lowered the resevoirs, and incresed your plants density to about 4 plants/sq ft, you might be able to make something happen down there.

I'm sorry, man. I know you've worked hard. But if you make some major design changes, you can probably still do some growing down there. But please don't kid yourself into thinking you're going to be pulling 6000watt yields from that space.

The other option is to put your bed down there and grow in your existing bedroom.

Thanks for the input and positive thinking.
Original i built the tube support with the thought that I would tablesaw them shorter after setup to lowest possible height. The reason for so many holes was just to have the option to move pipes if needed. I try to do as much construction above ground.

Your right about no possible with height. I dug a 2' x 4' 2 foot deep hole today and placed in a new resevoir. This should allow to keep water temps cool and also will take up less room and be tidier. Also dug a 2" 8' long trench on one end and put my pipe stands in it with another trench on other side dug out with a 4" pipe cut in half under them to collect return water and drain back to res. Now that end ofpipes sits 1/4" of the ground. The other side is around 3-4" high and drains great.

Since air cooled lights is not in the budget this round , bulb are going vertical. I also am not going to grow in the 3rd pot on each side all the way across all the tubes for light concern. Im thinking about a wire cage 12" around each bulb to help with plants growing to close and possibley a net over top of the tubes to help bend plants if they grow to high, wide etc.

So I will have 12 plants per 2000 watts and they will have an area of around 12" from pipe centers...so around 14-16" wide and around 9' long or so long and 30-32" of height to the floor joice's.

When I steel stud fram the other 2 walls it should bring the room to around 11x12' now. Humidity with 735cfm exaust with 25' of 8" hose and not really any outside intake is around 68 temp 72-84f (outside is 78-92f) with 1 bulb. The exaust is just on a table and piped toward a small opening just to help me work and will be redone with proper ducting and what not.

Im sore as fuck from digging , so will post pics tommorow with some more progress.

Oh ya...when i said just about done...... i think i jumped the gun a bit lol...especially since i hate sloppy rooms.

Yep. I totally agree with CG here. I think the only reasonable option you have is to keep the plants very short and use T-5's. You can mix the spectrum by alternating between 6500k and 3000k bulbs. I guess cooltubes could be an option if you were using 400w (or smaller) bulbs, but then your setup cost really goes up and you'd still need the cooltubes for that. Good luck bro.

Dude, friend, bro, buddy...I dig your zeal, but it ain't gonna work with 1000's. And definately not 6 of em. You may get 1 or 2 1000's in there with a few plants around them...but that's it. No real yield to be had from this settup. Maybe a row of vertical 400's down the middle and plants on either side. A basic BAVERB settup (bare vertical bulb). But the distance you need to keep the plants from 1000's is killing you. Maybe you'll just have to see for yourself that it's a waste of time. I'm trying to save you the grief. Go get a bunch of T-5's. Now that you've lowered the pipes, they will work perfect.

it would work better with 400hps. spaced closer together also it could work if you have a shit load of exhaust. but really 400 would work better just us more of them.

This just looks like a bad idea, the 1000's are definitely not going to work, i would take the advice and get the T5's and not waste your own time and a money. I also was thinking about how you are going to keep it sterile?

I layed down 10 mm poly on the floor and then thick roofing tar paper on the floor. The hole area was shopvaced top to bottom, sprayed with bleach and water then the 2 walls where polyied and the other 2 will be framed and polyied as well. I have a/c if needed..I think everyone is right about lighting , so i may have to bite the bullet and get air cooled hoods. The bulbs being vertical are not going to cover enough area when plants are big.
As for digging out the crawl deeper ....way to hard!!

There was a guy named bcsog that did the same size setup with 1 gallon pots, but i have not been able to find any pictures that will actually work on the net. Im sure he was aircooled.

Anyone know where to see any of those pics?

Thanks for the input so far.

you say youve got 30-32" from the pipes to the bottom of joists.....so if you subtract the hight of the light reflector ( coolutbe = 6" ) you end up at 24-26'' ...... if you can get a screen at aprox8 inches above your pipes and start weaving them in at a young age, you will be stylin as long as you keep the temps down, and keep airflow underneith the canopy as well
goodluck man im rootin for you and i'll be whatchin!

Are you going to try and use 1000 watt lights in reflectors? What is the current distance between the joists and the top of the grow pipes?

i think he said 30-32 inches from top of pipes to bottom of joists.....if you mylar/fireboarded the underside of the joists, you could lay your cooltubes almost touching it ( 3/4"-1" space) giving you around 24" of grow space;
i've come to start thinking that 1ks might be overkill for you(OP), there is such a thing as too intense... and dealing with all that heat when you dont need it, if you can get 600watters to 12 inches from canopy (thats a screeen around 8-10" above the growpipes) you're LOVINGLIFE!
thats just my 2pennies
