Co2 and Temps

So CO2 during flower will cause thinner stalks? can anyone else confirm this? should i only be using CO2 during flower?

I think you were reefer-ing to the post that mentions using co2 during VEG and early flowering will increase stretch. I use co2 during veg but only at 1000 ppms, cause i flower early from clones in a sog.

haha yeah that is what i meant, CO2 during VEGGIE! sorry for the confusion..

That sucks I can't get 400cfm through a 6" duct. Do you think that a "Y" adapter connected to two air cooled hoods would be able to pull 400cfm? It is kind of like pulling through a 12" duct.
The reason I can't put a window a/c unit in is I have a "window box" over my window and exhaust everything out there. I can't mount an a/c there so I will have to get one with the exhaust duct on it.
After reading about your ambient temps, I am now thinking I am not doing too bad. My ambient temps are 78-81 degrees and my cab, with all the fans on, stays 4-6 degrees above ambient. I guess I will just have to get that a/c for me to be able to do this correctly. I am hoping to get the a/c in the next couple of weeks. If not, it will be purchased before I start flower again.

- I vent 4 600W lights through 6in flexible ducts, then through a carbon filter. I use a can fan, i'm not sure what the cfm rating is, but it's a 10 in fan, made for the largest carbon filter. I vent through two hoods each, the to a "Y" then to the fan and filter, pulling air.

I tried pushing the air through, but the pressure kept blowing the ducts apart.

I don't see any problem with static in the duct, and it runs about 15 feet into another room (furnace and water heater) with the filters and dissapates into the house.

I only grow in the fall-spring season, so i don't have to use my heat, and i'm not wasting electric in the summer using ac. I can't wait til october.

I run 6-1000 watt hps ducted with a co2 generator ac and a dehumidifiyer and a digital sentinal climate controller during the summer my ac can't keep up with the heat and when my generator kicks on my temps range from 85-97.I keep my c02 ppm ranging from 1400-1500 consistently.I've had no problems with my plants and on a two week veg with 8 weeks flower i pull about 2lbs a light.

well I'm going to have to agree with the 75 degrees but i dont agree with the 1500 ppm will kill your plant. I have been using co2 for 5 years and i run up to 1800 ppm and they have al done well. But i grow in soil not hydro.

75 degrees is better than 85 and 95 is asking for big trouble. Growgordi is right in that aspect.

this thread is a year old in case you hadnt noticed......
