I'm thinking about buying a c02 enrichner to go with my setup. I'm wondering if it's worth the money and at what cycle c02 should be added.
 
co2 can be added anytime some wait till its flowering. What kind of ventilation do you have is there a lot of fresh air in your space?
 
I have never grown before (yet) , but i do remember seeing a high times growing video on youtube saying that CO2 is not nesseccary for marijuana. was this false information?

co2 augmentation IS NOT NECESSARY, but co2 IS NEEDED TO GROW ANY AND ALL PLANTS(that i know of). so as long as you have like 150+ ppms of co2 present in your space then plants will grow. but aprox 1500ppms is the optimal amount of co2 in your air. :blsmoke:
 
My CO2 generator is in my flowering room, I'm sure lots leak into my clone room but I never measure it. Keep your flowering room at 1500 PPM right from the beginning of flowering.
 
You use it in flowering only, the reason? you want the flowers to grow nice and big, not the leaves. When a plant is flowering all of its energy is used to make the flowers, the CO2 helps that along a good bit if PPM levels can be kept around 1500-1600 PPM. Its wasted on veg growth and during lights off.
