Running co2 during DSM

BilboSwaggins

I was reading a thread on Plantedtank.com or something like that and a guy was talking about using co2 during DSM and how it's heavier than oxygen so it pools by the plants on the bottom for them to use. I was curious if anyone does this or has done this. I'm testing it right now but I've also never done DSM so I have nothing to compare to.
My main worry is if I'm potentially gassing my room with co2? it's a pretty small room. Currently running very low co2.

Never heard of it tbh. I would think the plants have more than enough Co2 to get from the air especially if you are doing a DSM.

Co2 concentration in the air is 400 ppm Once your plants go under water they will need to adapt to living off just 10-30ppm. So in the long term I can't see how adding even more Co2 during the dry start will help. Light is probably the limiting factor here. Higher Co2 availability during DSM might make it even harder to adapt to underwater conditions...

Thanks guys, I thought it didn't make a whole lot of sense but figured it wouldn't hurt to try. Will be stopping the co2.
