Sealed grow room

Wow. Im shocked at how few people here havent even heard of a "perfect" sealed room. In my opinion it is a necessity if growin over 2000 watts in flower alone. By itself will add 1/3 more bud to your harvest. I am running a 4000watt sealed room w/co2 injection which i must say isnt that expensive. It is the original set up that is costly. I have 3 20lb tanks and for me i can ussually make in a 6ft wide by 20ft long & 6ft high can make it 1 tank last about 6 weeks so approximately 30dollars to have your yield enhanced by a third is less than your electric bill for thos 6 weeks. I thik co2 burners are the way to go in a large opp./ for me co2 injection has worked wonders took me from max 5-6lbs to easy an ten pounds. Which allows me to go for quality over quantity as well as having complete control over the room. If you are not growing this way you should seriously consider it. Peace, M3

I run a sealed set up and have big fat potent buds. I started with a traditional intake/exhaust and as I added more equipment eventually became sealed. The final piece I need is a split ac to be truly sealed because right now I have an in room 12000btu ac vented outside the room. Grunaire seems to have some very nice split ac units. I'll be having one delivered this spring. Peace!

Hey guys,
this might be a stupid question but if you have to exhaust your a/c unit is the room not a completely sealed ?

Is it necessary to exhaust the ac or will the plants die?

In sealed rooms you have three options for cooling.
1. Swamp Chiller: 2 fan, 3 fan, 4 fan..They use constant water circulation through a large radiator type grill with fans that blow the cool air out into the room. They are self contained and just need water in, water out, and humidity drain that you can just run to the same water out line.
2. Water/Freon A/C: Self contained unit that uses both water and freon/compressor for cooling. It sucks the warm air in from the room, cools it through radiator type grill/water, and freon then blows cold air out the top of the unit.
3. Split system A/C: This is a 2 to 3 part split system. There is an air handler which goes in the sealed room, then an outside compressor unit in a 2 part system. A 3 part system you can separate the noisy compressor from the outside condenser unit and put the compressor in a sound proof room if you don't want noise from the compressor outside the room.

With the split systems you only have electrical wire and copper freon tubes going outside the grow room to the outside a/c units. Biggest hole you need to make is 1". You put the copper tube and electric wire through the wall then seal it up with expansion foam or silicon etc.
With the water units you just need to plum the water out to your in shop drain etc..They go through massive amounts of water so you should be on city water supply for them. If you are on a well for water supply the split systems are better.

Thanks yoda
