I have a small space which I want to use for growing. But because it is freezing outside and can’t seal the environment (wall cracks, old windows, holes, etc…) I am wondering about my options now for co2.
I dont want buy co2 equipment, also I think the co2 will spread and I will fill my living room with co2.
A propane co2 generator would be cheap but flood my living room with co2 and humidity
For external air intake I could use the sewage and exhaust in the chimney (Edit: should be the other way round), but I fear that the air will be too cool when it is outside freezing temperatures below 0 degree celsius. how to use external air at freezing temperatures?
Finally I was thinking about not using supplemental co2 or external air at all.
If my home is not sealed and if I am living in it, what to expect? If a person is living in the apartment co2 levels should be high?
or how about doing yeast fermentation? how long can I have yeast ferment without killing itself because of too much alcohol? Is there a reaction where there will be no alcohol?
I would expect there is, but I don’t know. I do know that a 19’ tall greenhouse is reaching 800+ ppm CO2 with small plants, and hit as high as 1500 ppm during the initial wetting/mixing of the raised soil beds.
Do not use the sewage line for intake! There is a reason there are p traps on every drain. They hold water to keep the deadly gases in the sewer from coming inside
I’ve been growing in a spare bedroom, in a tent. I just have oscillating fans in the tent. I leave the room door open at lights on. Sometimes I’ll leave the window open for a little while but that’s a rarity. Idk if it makes my plants suffer or not.
how you prevent getting cold air in your living area? you use a flap which prevents the air flow at lights and fan off?
yeah I am still wondering how to do intake and exhaust in winter. In this case I am wondering how to do it if you not use a box and the grow near your living area.
maybe I should just connect a fan with a carbon scrubber to the chimney and have no special intake. then time the fan to every 20 minutes to run 2 minutes or something? Would that be enough?
I’ve sort of accepted that my situation isn’t ideal but I’ve learned to make the best of it.
I considered boarding up the window and popping 2 holes, one intake one exhaust. I might have to do that in the dead of summer but for now a little winter chill is what I’m forced to deal with.
It just means I have to pay attention to the window relative to how cold it is outside. Not ideal, but ok.
I don’t know that you need an intake, if you’re exhausting air should come back in passively. Houses aren’t really air tight so air should flow. If you’re exhausting more than 500 CFM you might want to look at a make up air unit to return air at normal temps, especially in cold climate or you can chain furnaces.
Not sure you need the CO2, back when I did wine you can get it to about 12% before the yeast dies. Cheap way might be to ferment some molasses and make some rum after it’s done burping, have to run it through a still to get higher % alcohol.
If you want CO2 without all the equipment, you can try a homemade Generator which consists of two jugs, some tubing, yeast and some water. you will not get a lot of CO2, but will get some.
what is a make up air unit which return air at normal temperatures?
what means chain furnaces?
Dont understand :-//
How quick does the 12% get reached? Are we talking about pouring a pound of sugar every day? Because I fear starting to brew will be too much effort. (Go to supermarket buying stacks of sugar, after couple of days throw it away and start again)
