Nope. Just want the CO2 portion.
do c02 levels need to come down during night hours (while flowering)

I have a Honeywell c7232, pretty basic but cheap and effective to maintain 1200-1500.

I'm not running CO2 now due to logistics of a sealed room but thinking of hooking control up to exhaust so when levels drop it will bring in fresh air to replenish air, any thoughts?

Won't get you any higher then ambient, which means the vent will stay open all the time.

I don't want it higher than ambient, I just want it not to get to low, my exhaust does not run all the time in the colder months so thinking the room CO2 levels drop to less than optimum. And yes there would be a bit of a differential so hopefully there would be cycling.

In later flower i dont touch that chart. Only in veg and early-mid flower. I like to drop temps and rh in increments as the weeks and plants countdown. At close to chop (and one room is fairly on the same schedule) my split is down to 68 - 70 degrees and rh is 40 to 50%. But i start high.

Get yerself that Autopilot desktop Co2 reader for 100$ or so. Even if not running gas....its a handy little monitor. Its a trip walking into the room and seeing ambient co2 ppm rise just by breathing. It was alot more than i thought.

The controller I have does that as well but haven't powered it yet and yes I will tie it into one of the 24v supplies I have in the room. I also have a couple of combustion analyzer's but never checked levels. Just started to think maybe it may tweeking things a bit to maintain at least close to atmospheric levels in a semi sealed room.

Yup, when I need a co2 controller I buy autopilot nowadays. I have their digital one and their analog one. Both work good, no problems. Naturally, the analog one doesn't have fuzzy logic, but I use them on generators anyways. And it does actually give a readout of current ppm's through a serieries of blinking led's.
I still have a few old C.r.A.P. Ppm2a's in action too though

Holy crap!! I remember why i didn't get one before. $530 bones just for the controller. Looks like 115 for the regulator. In a none sealed 8x8x10 room how many bottles do you think you use a week?
Anyone tried the analog version? $200 less...

I found a reg on eBay for $40 so i got that on order. I watched a video on youtubes and the guy didn't even have a monitor. 15min per hour on. I see Aero uses the old Cap stuff, i was looking at a few used ones wondered if they were good enough for a small time runner.

Your local Hydro Shop should give you 25% discount from the start, if not ask the next shop how much would he like your business. My shop keeps a running total on me and it's embarrassing how much I've spent in the last 5 years. So much I changed dealers just to spread the love, oh and a cutie behind the counter at the new place helps.

I have two of their analog ones, but like I said, i only use them on generators. They work fantastic. For bottle co2, you really want fuzzy logic. Not a must, but def better.
I don't use co2 in non sealed rooms, so I couldn't help you with that question about how long they would last in your situation. I do run bottles on some of my setups though. I run 20lb'ers in one of my small rooms. 3-DE lights over 2-4'x8' trays in a 8'x 20' room, a 20lb'er lasts roughly ten days. I use 50lb'ers in a couple of my little bit bigger rooms. One of them is 12'x 14', the room is damn near full of plants, a 50lb'er lasts around 2.5 weeks.
25%?????
Holy shit dude, do I miss being down in the bay area for that reason. Up here, I only get 15-20. Usually only 15, an I spend lots of money

Had one grow shop and she was a bitch of an old lady, main helper was nice. The helper and one of the customers that frequented the place opened a place, put her out of business within 6mo, then they closed up shop 8mo later. Nothing local anymore that is directed towards this type of crowd, too much online stuff i think for my area. Had to order net pots online the damn local nursery couldn't get them.

Autopilot and Blueprint (sunleaves) are much better quality than the old C.A.P. products. CAP stuff was a joke and the owner ran that company in the ground. I believe thats how Sentinel stuff came about. Ex CAP employees got fed up and started Sentinel. Ive got Autopilot stuff. Solid in my book. I like thier atmosphere and controller gear even more than Titan. Prolly all made in a few factories in China but i still like Autopilot better. I have a GrowOp master digital timer that was really inexpensive and is awesome.Yup, when I need a co2 controller I buy autopilot nowadays. I have their digital one and their analog one.

I too would never run gas in a vented room ever again. And never again even think about suggesting a timer based co2 system. I ran gas ljke that for along ass time. Wasted alot of money in unused gas thats for sure. Oh...and around here 15-20% discount at best. 25% at a couple stores and thats only if the owner is there. Got a super deal on another 8 bulb t5 recently.I have two of their analog ones, but like I said, i only use them on generators. They work fantastic. For bottle co2, you really want fuzzy logic.

I believe (but have been wrong before) that as the price of smoke drops and outdoor and greenhouse grown becomes more popular in the coming years....the indoor hydroponic hobby shops will start folding up like lawn chairs.
