Need Co2 advice

[MtnLionCO]

the window open 1 inch would be in a room adjacent to the grow room, not the actual grow room itself. the larger your house is the easier it is to control the ambient conditions.

MtnLionCO Reviewed by MtnLionCO on 01-06-2011. Need Co2 advice Just picked up a tank of Co2 and a regulater and need to know when and how it will work best...setting etc. want to try to do it right the first time for sure.. lites run about 18 hours a day in this room. We strung some 3/16 hose into the T5 room and drilled holes about 2 inches apart under the T5..when would be the best time to run Co2 in this room ? also do we need to turn the fans and can fan off when we turn the Co2 on..? Main grow room under the 1000 sodium lite we where Rating: 5

animals emit co2 and plants will use up all the co2 available and in turn emit oxygen which animals consume as much as is present. its a wonderful symbiotic relationship.

now tell that to Al Gore.

I wonder what the source is?

maybe you lived over an old coal mine or something? malfunctioning water heater?

earth ambient cO2 is ~388 ppm

[copobo]

It's not called for in flower either. lmao It will make your plants veg like no other.


Some strains dont like it so hot. Not all of mine were happy at 85-88 so i'm at 82 now.



Really? I run perpetual harvests most of the time so I wouldn't know. [attachment=o262556]:jointsmile:

not that kind of swell. Calyx swell. I've also heard it decreases potency. I get more crystals when CO2 is not run the last two weeks. If I get some time, I'll pull out some bubba I did an experiment with, one w/co2 off the last 2 weeks, one with it on, and take some pics. The difference in resin production is noticeable.

I wonder what the source is too? I doubt you could get co2 levels that high (not that it's super high) without supplementing in your home... unless you have a smaller home, very well insulated/air tight home, or you have lots of people/animals within your home. Like COPOBO said, a malfunctioning water heater or something to that extent sounds more likely. Not to mention, atmospheric CO2 is only 388ppm. I can sit in my grow room(which is only about 20 cubic feet) for 2hrs and the co2 ppm will go up to 2000ppm. Which is why I say it must be a small area. I don't know what your grow conditions are or where you're located, but it must be hard to control the other necessary "grow room" conditions with an adjacent window hanging open? Especially with changing seasons?


By the way, I believe it would be much easier to control ambient conditions via smaller areas... not larger ones. Why do many scientist/researchers do their test via small scale, rather than large? Larger areas take a longer time to acclimate than smaller ones, therefore smaller areas are easier to work with.

You're right though, it is wonderful. Although, I would call it the beautiful cycle of life. Symbiosis is defined as a relationship between 2 unlike ORGANISMS. Last time I checked, CO2 was an ELEMENT.

BTW, I know I sound like an ass... but I'm truly not trying to be one. I just don't know how else to word it. Sorry.

i can see symbiotic between plant > person w/the person providing co2 and the plant providing thc

[grobro]

what do you think the max co2 ambient level 'could be 'just with a door/window open /closed ......without a co2 add.....non sealed room....
plenty of flow.....w/exhaust fan suckin it thru....?
w/circ fan also.......
basement w/grow room within it....good clean fresh mountain air......guess i really need some type of metering $........to really know eggs ackley

ambient here is 370-410 IIRC when I was first setting up. (5100ft) I think mine is influenced by something local, making it a bit higher. I think next time I turn it off for 2 weeks I'll bring the sniffer to my desk and watch it for a few days.

I felt like I was pissing in the wind w/out a sniffer/controller setup..

I have mine to kick in at 1200ppm and turn off at 1550 ppm. humidity of 80% dumps room air. Temp of 92 dumps room air (considering turning this up to 95). A photo sensor won't let it add co2 at night.

For me, my vegging plants are always way ahead of the flowering plants. I want to start 12/12 with them smaller. (they are going in at 5ft now) I already only use t8's and have ppm's dialed back to 700... so CO2 just isn't needed in veg for me. ymmv.

thanks for the input..........good meter $ ?....brand name?......
low tech baking soda method?.......co2 bags?.....

[copobo]

you don't want to mess with that crap. I think just setting a tank on a timer would be more cost effective than that. If you are thinking about doing co2, you plan to do it from here on out, right? so why fuck around and do it wrong first? You'd be better of waiting and saving your $$ and doing it right. In the mean time, keep plenty of fresh air moving through.

google this
C.A.P Air-3 and C.A.P. PPM-3=
one is the sniffer (monitor) and one the controller.
