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 thinking of doing the same thing or should we run a individual hose to each plant ? also when would be the best time to run in this room as the lites are 12 hours on and 12 hours off.

also about where would be the correct setting on the Co2 flow meter..we where thinking about 1000 to 1200 ppm but someone told me we could run this higher and up to about 1500 or so....
thanks for any help you could give us..we just do not want to mess up our first crop. imp:
