@CRiSPrGrow, No it doesn't worth. That's an old school way to give some extra co2 but it doesn't worth. When these methods developed the knowledge about growing was not that much and people were doing a lot of weird things. They still do......:smirk:. Anyway the co2 that a spray like this can give is literally nothing and it creates moisture which raises significant the chances of having mold to your buds..

@CRiSPrGrow, The reason we make the substrate airy is because you need the oxygen, not the carbon dioxide. While studies have shown that roots can absorb co2 through their roots the same steadies have shown also that the amount they absorb is so small that its not worthy of mention. Also the steadies have failed to show if the plant uses the co2 that is absorbed from roots, how and what for. The amount of carbonates that are presented naturally in the water are way more than what a plant could ever absorb through its roots. Do not use ( co2 enriched ) carbonated water, because beside the fact that your plant doesn't need it those carbonates react with hydronium in water and make carbonic acid. The carbonic acid lowers the PH and as you can imagine this will give you a lot of problems....

@CRiSPrGrow, Not as far as i know . Heat affects the photosynthesis rate (because of the stomata closing) , it makes volatile compounds like terpenes to evaporate and polymerize leading to tasteless buds and makes compounds like cannabinoids to degrade.

@Iop420, Thanks man. :facepunch:

@LockDownGrow, Thanks ! :facepunch:
