CO2 and temp question!

[Puffin Afatty]

If I change over to a 1000w set UP, and move the wall to make grow 8x8x8, I'll invest in a controller and gas tanks for sure :aok: the kerosine heater doubles as a heat source in winter, so it's economical, but it's messy and prone to failure if not constantly maintained
beer buckets do well in warmer weather, but again maintenance is time consuming

:farm: tanks make perfect sense too, clean/easy/accurate

Yeah I had a couple 50 gallon tanks left over at the shop from the mig welder we had. They cost me 20 bucks to have both filled. We have tig now and the gases we get come premixed in a single cylinder. My how times have changed. I was looking at co2 generators but can't see the justification if I already had the stuff for compressed gas injection laying around. I am going to runn 1200 at first and then knock it up to 1300, 1400, and 1500 to see if there are any ill effects before making my final call on the best setting for my room.

I hear 1800 ppm is where you want to be at. At least thats what the Urban Grower sais, he is pretty much my hero.

Thats borderline if you ask me. I quess if all you have to do all day is monitor them and you room then that would be fine to push the envelope. I on the other hand do not want to tempt fate, I have the worse luck. Hell I am still fighting two spotted mites as we speak.

If you have a monitor and a regulator, you shouldnt have to be there at all, i dont know, im such a newb, i dont have ANY experience with co2, but on my next set of clones, i want to try, i just need to cut down on my air flow, its way too much for a small flow co2, wouldnt do me any good.

This is what I have managed to learn. In a typical grow room, you want the temps to never go below 60 degrees F and never above 80, but when using CO2, all bets are off. I've been told an increase of at least 10 degrees is needed, bringing a grow room that is 70-75 degrees to 80-85 degrees. The reason is the plants need the extra temp to help process the co2. Think dinosaurs and stuff. When the earth was younger, there was more heat and co2 in the air, and that made ferns grow to gargantuan sizes, among other plants.. Im no dinosaur scientist guy, but I've seen Jurassic Park, and I know that heat plus co2 means gigantic plants... Also, the ambient level of co2 is going to be about 300-350 in the room, you will want to raise it to 1000-1500 PPM (parts per million), anything more is pretty much a waste of co2. This is accomplished by placing a regulator on the tank with a timer that sprays every so often, once an hour or so. So, temp increase is about 10 degrees, up to 85 degrees F, and the lowest is 60 degrees, no lower... Hope it helps..

Props to Hangshai, he nailed it.

I ran CO2 for quite a while. It REALLY helped and I saw BIG Yeild/Bud density improvements.
I also used the same Controller you have Buddy. Best of the Best. Fuzzy Logic rocks. It took a few days to "learn" but after that, it worked like a charm.

You will get more benefit from the CO2 if you run your temps 85-90 degrees, imo. This will cause the plant to transpire and utilize the full potential of the CO2. Average CO2 in normal air is 300-500 ppm. Run your CO2 @ 1500ppm.
I am sure you know this, but make sure your room is air tight. Do not have a constant Intake, the CO2 replaces the intake air.

With that controller you have, you will have no issues of "over CO2in' " your garden.

Good Luck and I think you will love that set up u have!
