Co2 Controller

[Red1966]

It can interlock the temp and co2 so both won't run at the same time if you're using fans to control temp and humidity.

fuzzy logic or regular co2, temp (heat and cool) and humidity.

cheap too :/
Goddamn atlas 3 cost me nearly 5 bills.

 

[dbkick]

Hey OP , wanna buy an atlas 3?

Got mine off Ebay-$250.

Be warned it will only handle 1500w. I use solenoids to limit current thru the controller.

I may sell my titan atlas 3 and go with Sentinel then. They do ppm on co2 also , correct?

They do, but from hard personal experience my suggestion is to get separate controllers for CO², RH and temps. Reason is that if one of those fails, the other two are unaffected. With an all in one, you're dead in the water.

I do have separate controllers for temp/humidity(although the humidity part took a shit, a C.A.P. shit) but I'm not sure how I can set this up to not cycle my co2 controller every time the exhaust comes on since it's probably not good for it.
OP, sorry, you've been hijacked!

Hey Red1966, how the fuck are you?
I'm in the mood to say today, I'm sorry for some of the nasty comments I have made, that could seem to be disparaging you. You are a OK dude, it's almost always bullshit that I write, so don't take personal offence when I call you a dick, because most of the time I don't mean it. (Step 6, and I'm glad it's over)
The acid is just kicking in, so don't believe what I just said, but if you do, have happy dreams.

Anyway, CO2 in a small enclosed area will not work. The venting needed to extract the heat/smell from the grow area will suck it out as fast as you present it. If you burn to create the CO2, just think about the heat you create in your space, because it will get a LOT hotter. If you use tanks, explain that to the delivery guy, considering to do it right, you need large tanks, and then you have to deal with them. For what? A shorter grow cycle? Been there, done that, save your money, and the hassles that come with CO2, and just wait the extra week for bloom, which is the only thing that it is good for, not bud size.

because u can do the same thing as a controller with a timed release ............a area under 10x10 is small so they only need a regulator that release 0.2 to 2 cf
here is mine
my area natural ppm is near 500 ..........to raise my area to near 1500 i need to release 0.2 cf for 45 mins it raise my ppm to 1500
here is a calu to help
https://www.hydroponics.net/learn/co2_calculator.asp
that give u the basic info ........run time on a 20 lb tank or a 5 lb propane tank

this one has a natural ppm part
https://hydrofarm.com/resources/co2calc.php

if u run the numbers u will see the flow rate is under 2 cf ............when u go above a 10x10 u need to use a regulator that is 0.5 to 15

Co2 is supposed so be constant and stable in a garden, hence the fuzzy logic controllers that keep u in a very right ppm range (50 to 100ppm deadband). Co2 flow meters are so inaccurate it's not even funny. When running on a timer, realistically, your flooding your room to 1500-2500 ppm and then letting it back down to natural levels, all in one hour. (dropping rates depend on how well sealed your room is, if u run exhaust...ect)

Why try and knock the dude off co2.

If you're handy with electrical circuits, you could have a relay set up; when the thermostat wants to run the exhaust fan, it hits the relay. The OTHER side of the relay runs the CO² regulator. This way, it would only push CO² when the exhaust ISN'T running.

The other way is to buy a modular greenhouse control system. More of these are hitting the market, which should bring prices down for us hobbyists.

I don't think this is quite a hijack; the OP could use such a setup as well, right?

Really, I don't give a fuck what he does. I am only expressing my experience and opinion. You tell me how to simultaneously present CO2, and exhaust heat at the same time? No, that's right, you can't, because it is impossible. It will only work in large areas, like greenhouses that need to produce a quick product. Try it in your basement, a closet, or anywhere else that you can think of for somebody that is growing say, 2 or 4 plants in his basement,, or a tent. What I am trying to say ,and pass on my personal experience, and if that throws him off the CO2 bullshit, good. It's hype, and only costs you money and headaches.

Oh I don't think I'll bother, I heard co2 is hype, bahahaha.

it's only good for killing spider mites I heard.

You need a little better attitude, Your first words were pretty harsh sounding. If you want to know how to burn co2 and control heat you use one of these... co2 cost nothing for what it does.

Doesn't work. Tried it.

The higher atmospheric CO² gets, due to man's influence over the climate, the less need there is for CO² supplementation.

The higher temps needed to make it work also tend to work against top quality product, as it tends to get airy and shows less trichome production.

was only kidding but about the trichs. seems plenty with higher temps and co2 depending on the strain I suppose..
on another subject ,hope you decided on the lec 315s.

Had an informative conversation with the guy at advanced lighting, think I'm gonna pull the trigger on some of those in the next week.

Your right. I was a dick. I apologize
