Is it ok to have co2 run all day in vegetation at 1500ppm and all day in flowering at 1500ppm?

I dont have a relay to shut off co2 when venting is on which is 4 minutes every hour.
 
ya dude the whole point of having co2 is to have your co2 flowing in a sealed room then vent it like once an hour to cool down. If you are interested in adding co2 i would use a a/c instead of ventilating and then vent the air every1-3 hours and replenishing the co2. It going to take shit tons of co2 to be able to keep your ppms high enough with basically constant ventilation...plus man you dont want to be contributing to global warming like that think about YOUR KIDS or YOUR KIDS KIDS! That kinda stuff gives marijuana growing a bad rap.
 
that can work....not effecient at all but thats another story, if you are going to be running it constant then i would suggest attaching the outlet tube to the back of a fan that blows right on the plants, its not as good as the sealed room but it does work
