I’m going from a tent to a room and have a chance to build it sealed with a ac. Is co2 worth it. I have a 4×4 tent going to a 4.5×8.5 room.

I think it is worth it if everything else is in line. First dial in the environment/VPD, dial in the system/nutrients, then consider adding CO2. If the other two are in line, CO2 definitely adds yield.

Yeah my setup now dialed in vpd and nutrients. I currently run dtw 7 gallon coco in a 4×4 tent. I’m building a 4.5 ×8.5 room and wanting to switch to 8 6 gallon octopots. Was just curious if it worth the extra electric and equipment. Yield not the most important thing for my grow as quality.

In my experience, yield is the only change. Quality remained the same. That being said, the extra yield outweighs the cost of the CO2 gas.

Would you also need to run a ac. I use leds but being sealed I feel it would get pretty hot

Would I need to I meant
Absolutely need an AC for a sealed room. Will likely need a dehumidifier and/or humidifier as well.

Is it safe to run c02 in your home? I’ve been told it isn’t, but I tend to think it could be safe with enough detectors surrounding your room. It’s hard to justify the risk however. My mentor ran a burner unit in his basement. But he told me not to do c02 in my home?

CO2 is the best and the last thing you add to a grow setup. Its only works good in flowering though. So you dont need to add it in veg. If you get a PPM meter attached to the grow and which automate the release of the gas, its totally save to have at home. But be careful of smoking near the equipment 
Edit: Remember to get stronger lights If you get CO2 or it wont add as much to the grow. Also, in higher CO2 your plants like it abit warmer then normal.

It’s much riskier with a burner, obviously; even aside from the risk of flammable gas in an enclosed space, if it’s burning wrong it can release carbon monoxide instead. With a tank and regulator, as long as you don’t end up with a catastrophic equipment failure and leave it pumping CO2 into your house to the point where there’s not enough oxygen left to breathe, it shouldn’t be particularly risky.

Also remember we are talking about adding g CO2 to a sealed room, not the whole house.

Yeah that’s what I was thinking. It would have to stick open or blow a line to ever cause a problem. And with 3 detectors set up surrounding the room I should be good to go? I think that’s my next upgrade after this ssdd harvest goes.
CO2 is a heavy gas so it wont blend with the air without a fan. So you need lower fans blowing upwards in the tent and If you get leaks outside the tent it will float on the floor. I knew a guy who had a inline fan on the floor going out the window because he was worried about leaks. Ive always grown in basements, so ive never been worried.
Also If you have a larger tent you can make moonshine in the tent which will release alot of CO2 
Edit: Btw CO2 cant catch on fire, it does the opposite, kill the fire. You have nothing to worry about

I planned to flood the entire room with c02 as I constantly have an exhaust fan drawing air through my tents. So I’m guessing a sealed room with c02 is riskier than a system that works in the tent alone? I hope y’all understand what I mean.
The room in question has a small hallway behind the door and I was thinking of cutting up an old tent and screwing it to the walls ceiling and floor. Like a double door.
You have to use a PPM controller! Your plants will die If you have too high PPM. Also, the controller need to shut the Flow 1h-30min before the lights go out or you will hurt your plants. You also need to increase your light strength by around 50% to get good results. So 400w to 600w or 600w to 1000w and so on. Ive grown with CO2 for many years and If you have other questions you can just ask me. Ive done most mistakes through out the years

I’m upgrading my area going into a small room I’m building in the basement. Im planning on using silicone on the backside of the plywood around the studs to seal and hopefully enough frp to do the inside. If not it will be painted wood or painted vinyl covered drywall. Im a carpenter so kinda collecting material. I originally was wanting to go bigger but it just won’t work so 4.5× 8.5 with 7 ft ceiling the room. I feel like I can seal it pretty good just curious if it worth the investment in a mini split and all that

Why do you say be careful smoking near co2 equipment?? Co2 is not flammable… if that were true we could be fire breathing dragons lol

I would say for what you’re trying to do a mini split would be a great investment

I believe in your home… you won’t get serious effects unless you’re above like 5000 ppm… but that being said… at over 2500 ppm you start to get headaches etc… so usually normal air is 400 ppm or slightly less… 400 is the benchmark though… 1500 is the absolute most you want to go as anything past that is not beneficial to a lucrative roi… or in yield… I have mine set up but don’t need it unless it’s winter as my house central air has 1 vent feeding to my area… mixes our already breathed air with fresh and pumps it down there… it stays above 900 ppm on my co2 meter… not a cheap meter either… anyway… you can also go up to about 85 degrees f… check out blackdogled post about vpd and co2 just Google that it should come up… expect and be ready for quick growth!!!
