Help designing cost effective sealed room

[Undrgrnd Armory]

Yeah, you're going to need to create a negative pressure environment to prevent the smell leakage. Most do this exactly like you said, scrubbed exhausting.

Sounds like an awesome spot though Do it up right!

How would I guarantee my exhaust pulled enough air to work against the AC flow. I have had no problem with this in cabinet environments, but I've never had a giant closet or a full room. I guess if i treat it as a giant ass cabinet, I'll be ok.

It is kinda hard to explain exactly what I am talking about without a picture or being able to point at stuff.

But the way I see it, your way of just pumping some AC in the room won't really work. The advantage of my way.....it will work. It isn't my way, I just mean doing it the right way. To do it the right way you will need to punch some holes or figure out some way to get rid of hot air.

If you can pull air through your lights and exaust it out of the room then you are golden. So do you mean a closed sytem (air intake and exaust from outside, no room air exchanged) or would this idea you have exaust room air?

If you can suck air through your lights and exaust it, which would also suck air out of your room, therefore pulling in fresh air, then that is all you need. No portable AC, No CO2.

You would only want to do an AC unit (not your central unit) if you were doing a sealed room. I don't think a sealed room is what you should do here. But even if you were to do a sealed room the portable unit is not the one you want to use. portable AC units (unless dual hose) will suck all your co2 out of the room. You would need a window AC unit, or a mini split AC but that is expensive.

There is no cheap way to do a sealed room CORRECTLY. plus you are only doing 1200 watts which is pretty small and CO2 should be the last thing on your mind.

Looks like I'll be buying bags of ice every day. The cheapest sufficient rez chiller i saw was almost $600. I guess that will have to wait.

just don't do a bucket system. Get yourself a 3x6 botanicare ebb flow table. No chiller needed. Or if you are attatched to buckets do a ebb and flow bucket system.

Thanks. Good call on the ebb & flow bucket system. I don't see why that would be any more difficult to build. Great idea!

 

[pico]

I don't really see any reason to do buckets though. Are you trying to stick to just a few large plants or something?

Buckets can be a bitch sometimes. The ebb flow tables are really nice and since you are doing 600w lights you would be better off with more smaller plants anyways. would be easier to setup if you ask me.

But if buckets are your fancy, Dairy Queen sells 5 gallon food grade buckets for a $1. I have shitloads of them.

If you're handy, you can make a res chiller pretty cheap out of a mini fridge, a bucket, and some copper tubing.

Now that is some mcguiver shit right there.

Do they still have re-runs on tv? I have probably only seen that show twice.

I think last time I saw it was on like TNT at 10 am or something

So I just DL'ed the episodes

I am limited by my setup costs.

I have a big carbon scrubber, 2 600w lights with cool tubes, 4 outlet air pump, a 55 gallon industrial grade plastic barrel and some other other hydro odds and ends. I figured buckets would be easy and cheap to construct. I also worry about maxing out my area. I worry I would not be able to access the plants in the middle of the table. However, I like ebb and flow and I welcome any links to construction techniques DIY projects you might know of. I want at least 18 plants with an end yield of 2-3 oz each. Using northern lights x big bud and 1200w, I don't think that will be a problem.

I like ebb and flow thou

How much can you spend? A rockwool slab is like $65-75 for a case of 12. They are 3' long. Otherwise they sell for like $13. Go to homedepot and get aluminum (but painted) rain gutters and at least one end cap for each. They are 10' long and easy to cut. I pay 4.95 for them. There are other options too in the same section.. Look at the roofing for screened patios, they are like 10' long powder coated and 1' wide.. 3 of those would make a great NFT table and perfect for you size.. They cost like 20 bucks..

set up a saw horse table for it. you want one end to be a little higher, and the lower side will need to drain into your res..

run drippers to the slabs and your gold.

you can also use the panels, and 3gal poly bags filled with hydroton or a soiless mix, and run top feed drippers to that.. for the soiless you can water by hand..

you can just run soiless too -no gutters/panels, in 3 or 5gal bags, and hand feed.. they cost like 30 cents for the 5gal, 24 for the 3 and 18 for the 1..

you got options..but what is the budget and what do you need? (besides a system to keep plants in)

myself am budgeting too - so I'm running a soiless mix. peat, perlite, verm, lime and the containers are 3gal poly bags.. in total I spent like 60 bucks to give 40 seedlings a place to call home. the fact im starting from seed is also a motivator for this mix...feeding gen hydro. next round i'll be back in rockwool..maybe coco

Funny you should mention gutters. I just viewed this thread:

http://www.icmag.com/ic/showthread.php?t=37774

and I love it. I'd like to model my setup after this design. It will lend itself well to a long rectangular closet with a minimum of cost.

 

[Undrgrnd Armory]

I have lights and fans and a huge res. All I need is maybe a new bulb, a system to keep plants in (looking like its gonna be gutters filled with hydroton) and a water pump.

I already own all the real pricey stuff. Then of course I will need nutes. I bet I could get away with spending no more than $200 bucks for everything I need to have a kickass setup.

The way I described to setup the closet isnt a "sealed" room, yes when the a/c kicked on it provides some positive pressure but the blower sucking out provides way more negative pressure.

I had passive intakes for the blower so its not a "sealed" room, but it was certainly effective and it worked.

I have seen your threads so I know you can grow killer weed there are many ways to skin a cat though.

Yeah I know that setup could work with intake from AC and having another exaust fan sucking out. I just didn't see it working if you are trying to keep CO2 in the room. But if you are just using the AC as an intake and not doing co2 enrichment....no problem.

 

[In Vino Veritas]

For a 6" 440CFM fan, would a 8" duct connected to the AC work? I want negative pressure in the room - no leaks! I have the compressor/blower literally next to my room.. awesome.

That would be ideal, providing I tape off all the other AC ducts and move the thermostat.

I can't imagine that being too tough to do.
