I'm running 4 1000w HPS...Room dimensions are 13X13...Gonna run a Excel air conditioner and a CO2 generator. The hoods will be air cooled, will also have a dehumidifier. also gonna run a canfan/filter to scrub the air that will be sealed in the room for pathogens...

a sealed room maybe the best in yields, but on a scale smaller than 3kw lights, i don't think it's economical to run a 1kw A/C and expensive CO2 equipment and tanks. the cost would outweigh the extra grams, i'd rather add more light before getting CO2 if i am growing with a 600 or 1000.

The big thing with sealed environments is that you can totally prevent mold and pests from getting in.

im very new to growing myself.... but my partner (with yrs of experience) has our room set up sealed, at all times... yes, we have spent alot more on equip... more than i expected to run me at first. you have the ability to control everything..and as far as mold, thats where some extra equip comes into play. no venting at night no nothing. from what ive learned so far its very practical, but is expensve...

You still have to control the humidity, you can't just have 80% (for instance) RH and expect a sulfur burner to take care of things for you.

yes.thats called a sealed room or system.I prefer it to venting.If you can afford the extra electric,id def go for it.Use a split system as opposed to a reg a/c (window ac).Youll be quite pleased with the results especially coupled with the co2 supplementation.

Could any of the perfect room / CGE / sealed room people, please provide an outline of your design. I'm attempting to go sealed and am having issues.

Well tell us what your issues are?

Its not too complicated really. Just seal the fucker and run co2, dehu, and aircon. Sealed hoods and fans unless you really like running your AC

well typically you do need the ventilation to get rid of humidity the plants produce or you could have mold. However with the use of a airconditioning I do believe this would take the moisture out of the air. which is the main issue besides head when exhausting.

You need to run a dehumidifier. Period. Your aircon will never draw enough moisture out of the room. plus, I like to control my shit, not leve it up to the whiim of whats going on outside (humidity levels).

I'd like to run a closed system and have some questions. I have a spare bedroom that Iv been growing in with a 3x3 tent a 600w light with cool tube reflector and venting outside I'd like to upgrade and start using this as a veg tent and just grow open air in the other side of the room with a 1000w light for flower, would it be possible to seal the room vent the lights together and still be able to properly regulate these two

A friend of mine has six 1000w HPS umbrella hoods in a room in his basement. Uses AC to control the temperature but uses Co2 generators.

333,

Those closed rooms need to be huge,

I believe your missing a dehumidifier in your plan which consumes a lot of juice. like as much as the rest of the setup.

closed rooms work with a lot of soil

One gets mold bud on the small scale
