Talk to me about using Co2 in a small tent.

[daleharris]

I’m looking into if it’s anyway feasible or if I can add and keep a useful level in a small tent in a usually closed closet. With the obligatory exhaust via filter to the outside of house.

I can find the valve and regulator at first glance on Amazon for $50 plus or minus that comes with enough hose to work. Need to pick a reasonably priced monitor to place in tent to check levels it would seem, not a high dollar integrated system just a basic meter to look at and check. I presume the correct method would be to plug into a timer adjust regulator and only use during lights on ?? Not sure how it works even with my exhaust fan to the filter the vents outside. On slowest speed will it defeat the purpose? I can’t run without a fan especially deep enough into flower for smell and summer to help bring AC air into tent. And I have no idea how much Co2 would be needed per week/month before a refill on one of the small tanks. Basically I don’t know shit at this point my interest is really getting the best of me after all these years. I can’t use any kind of burner and seems the bags are a sales gimmick so a small bottle system is my initial possibility feasible path. Enlighten me on a reasonable budget.

Are you gonna vent your co during lights on?

I found a co2 monitor for an office space for $35 on amazon

Raise the CO2 in the room with some open flames of some sort. Candle flower pot heaters. Be sure to get a meter. Probably want to run higher humidity too to limit the air exchange.

Pretty easy to get up to 1500 ppm or so.

I am going to most likely have to. Don’t see a work around on that part. I just ordered a Co2 meter CO2Meter RAD-0301 Mini CO2 Monitor
to get some base readings.

Small tent you say; shut it up & sit in there & sing to them a few hours a day - meditate - win win

Usually people say it only makes economical sense in a closed system but I haven't done the math myself. You say you're exhausting outside the house (typical carbon scrubber shouldn't filter co2, only special ones) so... And also that you should have everything else dialed in before you bother, are you sure there aren't other ways to improve still? But sure you can hang up some tubing in there if you're dead set on doing it. Fan at lowest speed could bring mold issues outweighing the benefits I wouldn't do that.

My co2 "supplementing method" is to live in a (sub)urban area and take intake air from outdoors. Wonder if it will still work when everyone is driving electric.

Im not dead set on it but have wondered if its doable. Mainly because I do HAVE to run the exhaust fan some and how low I can idle it back remains to be seen. Historically I can to a point just before the smell starts to creep out of the grow space into the house or in the summer heat becomes an issue. Its not a lot of money really just need the valve and regulator unit I think and a reasonably accurate meter. Just not sure how much the exhaust fan even on low will effect the levels. And the cost of gas and how long a tank lasts when used at effective levels to possibly overcome the exhaust. I was also wondering how effective it is for those who use it. My light can crank out well over a par level 1000 plus (Cree CXB3950 Timber kit) measured by the Apogee meter.

Not crazy about more open flames in the room. Wife already has a few candles she insists on most of the time.

I think car exhausts pump out carbon monoxide not dioxide.
Easiest and cheapest co2 is a bottle hung from your hanging rail. Warm water, sugar, yeast. Keep topping the water and sugar up and change the water every few days. If you keep a small amount of the original water, you'll only need to top up water and sugar, but yeast is dirt cheap anyway. It'll produce more in warmer conditions, so higher co2 at lights on. Your room will stink though.

Do you vent outside?

Yes but technically to the attic area. Has been like that for years and it works well for me.

Thanks but Im looking for a less smelly method. I just ordered the meter and the regulator set is cheapish at least for a starter type one so I will probably order one this week and I need to find a local place that sells CO2 for restraunts and kegorators etc. Plenty of local places that service industry and food grade gas products. Will try to update in a few to pass on fail or pass.

Perhaps Buy a C02 monitor & learn something, of course I was joking about sitting in there many hours / day… but in closed up homes with humans, animals, furnaces, hot water tanks etc - my ambient runs from 340ppm summer windows & house wide open, winter time 800-1000ppm sealed up, furnaces running etc…

Look just breathing on it now raises it above 1000pm, the reading flashes repeatedly fast so our eyes see a steady # but the camera doesn’t

Knowledge is power; ignorance is bliss, sticking your head in the sand (ignore) is for children

I don’t even need my burner anymore due the knowledge I’ve gained from a quality monitor

I have two small tents in my bedroom. One is the veg tent but if smell is not an issue the CO2 accumulates when just exhausting back into the room. Sinks to the floor to with no air disturbance. Under 150w though for light.

I agree with led05. Not sure if you see his reply, or actually ignored him.

Once you get a CO2 monitor and check out the ambient levels in your home, you may be surprised. I sure was.

My living room (in a small house, two adults (one tobacco smoker), two large dogs and a cat) has around 1000-1400ppm. This is in winter with furnace running and closed windows.

My tent and the room it is in are basically in equilibrium around 400-800.

Really considering ducting an intake for the tent into the living room. Hesitant about the cig smoke though

Filter the intake? As said all except specialty filters should be ineffective for co2..

And uhh I'm sure you realize the noxious particles you don't want on your plants you are actually inhaling yourself now... I respect your priorities but maybe this ducting idea could be a good idea in more ways than one.

 

[greencalyx]

Haha, yep, win win situation for sure

I'm an ex smoker for about 6 years now. I figure cutting out 99% of the smoke going in my lungs is good enough. I've got an air purifier running 24/7 in the living room.

Honestly I was more concerned about my tent/plants smelling like an ashtray, lol

 

[GMT]

Huh, didn't know cars put out co2 too.
