co2 how much does it help?

[bluntmassa1]

I'm not using co2 right now but I was wondering if its really worth the extra cost of running A/C. is there a big difference in yield and/or quality?

try asking int he advanced growing section mate, i have never used it , but i am contemplating on it for my next grow.

Hey Blunt !!!

I use AC and could be without it. I have them in an attic flat though and the temps outside are soaring now !!

 

[welshsmoker]

are we talking co2 or a/c units here. confused again.

dunno .. never used it .. but Im a welder/mettal worker as profession so I have easy acces to Co2 and valves and what is needed to make it work ..

but realy .. I couldnt care less .. not wort the effort if you ask me ..

grow one more plant and haverst the same or do with 20% less ..

I dont need 20% more and is not wort my time if you ask me ..

I would have to make a lot of changes to my room and even tho I have acces to it all it would still be a pain in the ass to carry bottels up on 3th floor and makeing it all work .. cost of timers and a AC insted of my ventilation (not even possible at my place as I cant make holes or hang a AC out side on the wall)

just to much work in my case .. and cost .. even tho I have acces .. it will still cost me to swarp bottels now and then + the timers and all the small stuff that follows ..

and ther is also security .. as I grow in my appartment .. dont want to .. not wake up one morning ..


but hey thats just me and how I see it .. evrybody have ther own tast ..

Increasing co2 will help your growth in abundance. An increase of co2 over an ambient level of 360 parts per million increases greater resistance to heat stress, and other forms of stress. Better growth at lower light levels and improved root to top levels. Nursery men have been using it for over 100 years, it's proven.

Edit: Federal guidlines put the dangerous/deadly level of co2 indoors at 1000 parts per million. Make sure you can do this safely!

Im with kinetic on this....co2 works great in areas with little or no ventilation. If venting out is not an option u, u can easily supplement co2 for great results. This is how it's done in a totally sealed grown room.

 

[bluntmassa1]

so co2 don't make a big diffrence unless you can't vent out right?
it really don't seem to be worth the extra cost and trouble running co2 when you got good ventaltion cause like slipon said its only a 20% difference in yield so I'm thinking extra lights in a bigger room and good ventalation would be better for yield then sealing then adding co2 and a/c.

Correct because if you are running an exhaust the plants stomata does not have enough time to utilize the co@ you are trying to supplement. Also keep in mind your room temperature has to be at 80-90 degrees farenheit for the stomata to use it efficiently. Also you need a co2 monitor because if you slip just a little it can destroy your foliage that looks like ozone damage. Also co2 implementation is spiky and not a consistent flow. You are better off having an intake/exhaust system your getting the minimal requirements and always having a good exchange of aire flow.

everybody keeps talking about exchanging air, not needed. plants need water, food, light and co2. not fresh air. i have an extremely sealed room with no venting, no air cooling and a co2 generator. an extra 3-4oz every three week harvest is a lot of added income. how much does a qp go for where you are? here that is enough to pay for all my co2equipment in one harvest.

an extra 3-4 ounces on how big of a room? and your saying you don't have air cooled hoods and no A/C right? if so how high are your temps? cause I thought you would need to run an A/C to keep down the temps in a sealed room.
also did you run your room with just ventalation before you sealed it to come up with an extra 3-4 OZ just by adding co2?

that is an extra 3-4oz per 12 plant harvest every 3 weeks in a 6'x10' room running 3 seperate systems totalling 36 plants. i never said i didnt have ac, of course i have ac, its a sealed room. my temps are where i put them, 80-81 on and 66 off. i never had ventilation for my room, it was purpose built. i ran this room for close to 20 months without adding co2 so i could make sure i had temps, humidity, nutes, and strains dialed in, then i added co2. the only change was adding co2 and it was a visable difference.

Sounds like you could use some help trimming! I'll bring my own fiskar micro tips and some Widow!

 

[superstoner1]

whew, you were a little late. been trimming since 10am, 21oz in jars, 6 plants.
