Hi, i was wondering does it make a huge difference if i only turn off my extraction fans and leave the intake fans on together with circulation fans. I figure the CO2 will be better dispatched around the room. I plan on setting the CO2 on a timer for 10 minutes every hour when the lights are on and at the same time the extraction fans will be off. So the room will have CO2 for a total of 1 hour every 12hours @1500ppm. Is this a good idea or not. All comments welcome please.

StickyFingas Reviewed by StickyFingas on . FLOWERING = CO2 amounts???? i just have a very basic question. when i put the plant into the flowering cycle, does it need more CO2 during the 12hour 'lights on' than if it was in the vegetative state? thanks for any responses. take care Rating: 5
