swamp cooler and cycle timer exhaust - Growroom Designs & Equipment - International Cannagraphic Magazine Forums

swamp coolers cool by evaporating moisture in the air. so allowing relative humidity to build during off cycle to the high end and quickly exhausting...does this cool more, less or equal to constantly exhausting.

I am trying to rain my ladies with a shower of co2 during exhaust off cycles and dont want positive pressure to blast my house with odor...

Just not sure if I am better with or without the coolers...
relative humidity here outside is very low.

thanks for any feedback

The plants can't utilize the co2 w/o light is my understanding. My co2 always rises to 6-800ppm during lights off anyway without me adding it.

Higher humidity at night would not be ideal, at least in flower. If you can maintain good vpd it's ideal.

I dont believe building up humidity and then using a cooler would be more efficient than running the swamp cooler system. The air exhaust is needed for evaporation to happen, mine gets 10-12 degree cooling with the swamp.
