I have done hydro sog under 4 600 watts yeild a little over 2 lbs. I have done scrog soil 2 plants under 1 1000 yield a little under 1lb. I have done auto's in soil under t5 abt oz per plant. I have done 5 outdoor soil 6 foot plants over lb per but lost due to but rot. I have done hydro 1 plant per 1 1000 with 14 1000w lights over 1lb per plant. I have done ALOT of growing! I have never done a closed room where no fresh air is coming in and no used air going out. This time things are totally different. Im growing with the sun but in a wallipini or pit greenhouse and I want to manually add c02 and 02 I am flowering at 18" and giving 3foot spacing. Manicure will be top at every 4th node and lolipop. grow space is 30x20. Air conditioner and dehumidifier for climate/RH control. Grow medium Soil. Im looking for expert advice from EXPERIENCED closed loop growers. any questions just ask. Thanx in advance!

what u are talking about is a closed off eco system .....like in detailed designs for generational space ships or in inclosed bio domes
yes it is very possible but u do not have the area nor the money to do this.........u can not just seal off a room and except it to do well u need a massive amount of dead area to use as a reservoir for air or u are going to need one of the most effective Co2 scrubbers / AC units on the market that will cost u in 100,000 plus range

doing it would mean u need to have several tents going (tents because of the light) u will need to have half on and half off and switch every 12 hours ( the way plants work are when the light is on they use Co2 and make Oxygen ....but when it is off they use Oxygen and make a waste form of Co2 that is no good them)

so for this to work u need
co2 scrubber to remove the waste product from the plants .......living creatures in the room using oxygen and supplying Co2 that the plants can use( or tank suppyling it) ....a ac unit to control heat from lights .......to do a sealed room u need to make a mini earth in that room other wise the plants and that is not possible in a room u need a large area a house

oh not to mention the automatic feed system and watering water PHing
those alone i have priced out u are looking about 2000 for that 8 system feeding ( 8 different chemicals to mix into water) and 2 ph (one for up and one for down)


if u got the cash i can tell u how do this right with full control alls u have to do is enter to replace feeds and harvest (plant care if u want too )

it can be wired to a single laptop along with a system of cameras so u can vpn into the system and remotely control the room from anywhere with a computer

set the access to only allowing set mac addy to access .......for anyone to break in they would need to clone that number to even have a chance to access it .....mac addy are 1 time use numbers that are assigned to wireless /network transmitter it is one of the 3 numbers used to ID a computer as that computer

Take a gander into my last room. I have o2 and c02 tanks and regs. I have the cooling capacity, never asked for help on that, Im running a/c as well as cold sink and geothermal heating cooling. What lights do I have to cool? The sun is my light. This is a wallipini. There is no "Dead air". I am supplying 02 and c02. Plants require light,water, nutrients, c02 and 02 nothing else... You are not qualified to provide insight. Also why are you questioning my financial state? Also I have my water situation covered. I am not growing hydro this round. STOP assuming! View attachment 3352900 View attachment 3352900 View attachment 3352900 View attachment 3352901 I need EXPERT advice, which you clearly are not. This is not my first rodeo bud. I CAN seal the room tight and manually add 02 and c02, it will not cost me hundreds of thousands either. Anyone with experience growing in a 100% controlled environment NO air exchange feel free to comment. Do not comment to guess about things. 20140207_233214[1].jpg20140307_151714[1].jpg 20140406_123427[1].jpg

then it is not a sealed room ........what u were asking about and what u are doing are not the same thing ........sealed means nothing from the outside

your running a Laboratory control environment ..not a sealed eco system room

whats the question? Some advice would be make sure your cooling unit is big enough. make sure you have enough dehumidification. air movement. amount of burners you'll need. if you have none of this like dude said your looking at a pretty penny.

Why are you people worried about my cooling? I can effectively cool 14 1000watt lights, I will have no problem cooling anything. I have Dehumidifying under control. I have adequate air movement. I have adequate c02. I asked nothing about those things and you are assuming. I think you are more fit to go help a guy in his 4x4 tent.

My question is about the pros and cons. I want to hear about peoples experiences with this method. What they noticed what they learned in hindsight ect.. Im not asking how to. I have the how to covered. Im only looking to hear from folks who have EXPERIENCE with this method, and their insights. I dont want to buy anything. I have about 70,000 dollars worth of equipment 3/4 of which I am not even using on this project. DO NOT COMMENT if you do not fill the shoes!

You can run a closed system as long as your reconditioning your air. Sounds like you have that covered...

Not sure why you want a closed environment in the first place beside pest control.

I am reconditioning the air. Pest control is a plus but not the main reason. The main reason is to have a constant stable environment. In my experience bringing air from the out side can make massive temp spikes and drops as well as RH and intern causes issues. My last room was 12 x 24 and the amount of air I exchanged made it very hard to control temps and humidity. For example if I am in say 7th week of flower and I want to maintain 40-45% RH and 62-65 F and its July outside Temps can be 90F and RH can be 70%. When I pull that air into my room I am slowing growth risking bud rot. By time I get the air back to where I want it it's time to exhaust and intake again. That room had a 5 ton cooling system that worked HARD because I had 14 lights.

I use environmental controllers that limit the swings drastically. Much more cost effective than using the extra A.C. power in my 20'X30' shop.

If you set your fresh air intake up correctly it really shouldn't compromise your environment.

Greenhouses aren't very well insulated in the first place so your dealing with radiant heat. A closed environment woukd probably serve you better in an insulated structure IMO.

No need to post your resume.

Its not "totally different." I'll repeat what's being said, there's no real question. For basic co2 supplementation info please check the newbie central area.

I do have environmental controllers, in that Room I used cap 4. How did the controllers limit the the swings? Bringing in little amounts at a time? If that's the case how did you exhaust and intake the amount of cfm that room calls for? This room is insulated by the earth It's a walipini and solexx Roof.

I posted my resume to give an idea of my experience level, so that I didn't get silly replies like "For basic co2 supplementation info please check the newbie central area".
A sealed Room is totally different then a fresh air exchanged room. A under ground room with geo thermal heating cooling/ heat cold sink ,is totally different than indoor room with only hvac. My question is about the pros and cons from folks who have EXPERIENCE with this method, and their insights. It is a " Real question". I know all about c02 supplementation and have first hand experience with it. Thanx for trying to help but your reply offers me no insight to my very real question.
