There sure was a lot of mis-information going on in the earlier portions of this thread.
Still a little bit. Like there is no need for diffusers or piping to "drop" the CO2 from above the plants. Even a mild breeze from a small oscillating fan will mix it right into the rest of the air in the room.
No need for tanks, valves and solenoids either as I'm finding out.
I bought a simple GroZone USCO2 controller to hook up to a 70lb tank I bought a couple years ago at a yard sale only to find out that they won't fill it unless you have an account and rent a tank from them. They use a serial # on the tank to connect it to an account and with my luck it was probably stolen and I'll get the shit for it. $120/yr for tank lease and $124 for each refill so have to cough up $250 up front with tax to get one. So I'm sitting here with a $270 CO2 controller I can't use . . . or can I?
A few years ago I made an alcohol burner to add CO2 but had no idea if it was enough so stopped using it. Then thought why not use the controller to see if the levels go up with it. Do they ever! I only takes about 15 min and the 1500ppm LED starts blinking indicating it's over 1600. There really isn't anything in the manual about using it just to monitor levels so I emailed them last night to find out. Had my answers when I fired up the computer this morning. Had another question so replied to that one and had a response in 15 min. From the CEO of GroZone nonetheless. Talk about great customer service! A big shout out to GroZone!
made as well.
Seems I could have just used it right out of the box for that but being the curious cat type had to run thru the whole process and do the troubleshooting part too and it worked perfect.
This is the burner I made and today made another one the same but with only one wick for the veg room. Just a mason jar with copper tubes soldered to the lid and tiki lamp wicks in them. Bit of a PITA as it's all manual and I'm up and down the stairs a dozen times a day but after getting my leaky appendix out recently after 5 years of profound fatigue and all sorts of gut pain and cramps I'm feeling way better and need the exercise to get myself in shape after years of sitting on my bony ass. Burning about 200mls of methyl hydrate downstairs per day and half that in the veg room but it's the first day. I ran tape up the side of the jar and marked it in 50ml increments so I can monitor consumption. I keep them in a metal can or stone crock in the middle of the room so if the jar were to break the alcohol is contained and there's nothing above to catch fire. Getting a couple of heat detectors or smoke alarms just to be safe. Only $8 for a 4L jug so won't cost much to use.
Think I'm going to make a couple of smaller models to use less fuel so it stays around the 1000ppm range for veg and I don't have to run my temps up to 85 or so. Extra CO2 is proven to benefit plant growth at anything above the ambient 400ppm. Full 1500 and higher temps for the growth spurt during stretch and then back to 1000 for the rest of flowering.
10 min after lighting both wicks.
