New setup looking for large yields

[Opie Yutts]

The problem with PVC though is that it's not strong enough to frame in the AC or DH.

Not sure about this, you can build some pretty strong shit with PVC. You don't even have to glue it together, to aid in disassembly. But I guess it would take a bunch of vertical studs under an AC that does 4 rooms.

Well here I have to disagree. I've never used one. I'm pretty sure others don't use them. I would not buy one until I know I need one, and I would not put one in if I already had it, just because someone says I should. MJ likes 60 humidity. If anything I need a humidifier, since mine rarely goes above 30. If you get mold you need more ventilation, not necessarily a dehumidifier.

Like I've always said, I like to put a humidifier and a dehumidifier in a room and let them fight it out.

I guess that has to do with geography. Around here your humidity will go to 90% with the lights out, and I've seen that in a variety of different rooms/setups.

Wow, you figured that out? I wish I could figure out how to use 2200 watts of HID in a 4x4' space, without ventilation. Because an AC and DH damn sure aint going to do it. That is unless you are putting in one of those AC units that are rated to do about 4 rooms.

Didn't he say an 8x4 space? 2200 watts in a 4x4 space would probably be a different story (and overkill/inefficient).

a window AC unit and a DH framed in so that the exhaust goes outside of the gro-box does wonders. Don't knock it till u tried it. I bought an AC and a sophisticated exhaust setup, installed the AC, then realized air-cooling the hoods was frivilous... I returned 'em the next day... I run exactly 70-75 degrees, but it might be different in your climate/conditions.

Possible? yes
Better than wood? Not for me.


Between an AC and a DH you have about 90 lbs of weight, and for best effectiveness they need to be elevated. I'm sure there is a way to support that much weight with PVC, but I don't see a good reason to risk one of those tubes cracking and a 50 lb D/H falling on the plants. Also I'd rather hang my lights from 2x4s than on relatively long horizontal PVC tubes (unless theyre the really thick/expensive tubes). As far as breaking it down quickly, it doesn't take that much time to unscrew 20-30 deck screws, which is all you need. I"ve broken those rooms down in a matter of a couple hours before. Also wood is much cheaper than the PVC that would be strong enough for all this. I mean there's no doubt that you could construct one of these rooms with PVC, but it would be expensive. Wood also has the nice benefit of being able to painlessly mount instruments on it and add onto it with the pull of my drill trigger.

But to each his own. :thumbsup:

If you want to support something like an a/c in a pvc frame, you can screw a piece of plywood to the pipe and mount the a/c in the plywood. It has to be a pretty sturdy pvc frame, though. 1 1/2" is probably the smallest you could use.

I build everything out of wood too, but then I have the tools and the expertise to do so. Building a wood frame is easy for some, impossible for others. Almost any idiot can piece together pvc.

Also I was talking about in the context of hyrdo. If you have good ventilation in a soil garden I could see it possibly not being necessary. Again this might be a geography thing, 30% humidity in any context is unheard of around here.

True. I like playing with my wood. :giggity:

I too prefer wood, guys. I have a truckload of woodworking tools and equipment. Literally. I've got pressure treated 4x8's, and a pair of stained and lacquered oak dice that I CNC'd words into, and a lot of stuff in between. You guys that can imagine the workings of CNC woodworking tools, try to imagine how you can router words into a very small 6 sided object. I've worked with wood all my life and brought home a decent paycheck from it too. I've also built some things out of PVC that worked great and cannot be beat in terms of tear down. Not even close to wood. Just don't glue it together and it comes right apart. No screw gun needed, and no need to worry about if I charged the batteries, and whether I should wait for batteries to charge, or try to dig out my old corded drill. I also don't have to worry about if I should put the screws in my pocket and let them poke me constantly, or try to find some container to put them in, or try to remember what bin or bag I got them from, or whether I should sort them properly or just put them all together.

And I too was talking about hydro and 30% humidity. That's in my grow room, not my house.
