Supplementing CO2 in veg

Botany and Cultivation

The jury still seems to be out on the effects of lightly supplementing (~800ppm) CO2 during the veg cycle. I’ve read sources saying it doesn’t do much, some saying it only speeds it up, and some saying it makes a stronger/healthier plant. What’s this forum’s opinion on the topic?

I run 1500 and it definitely does lots if u run big plants and have everything u need to support it just like flower.

I have high 700s in living space with no supplementation other than two cats.

It’s very useful, but it needs to be supplemented at a specific time. You can talk to me. I’m a professional planter

That’s crazy. Is it calibrated? Only ever used them in gardens. I’d be weirded out if it were that high in my tent or home.

Holy shit, it’s the norm for households to have such a higher percentage than outdoors:

The jury is not out. Co2 studies are mostly on non cannabis and they all show increased growth. I say yes to co2 in veg, combine that with alot of training the plants and youll be set up for monster plants. You want to keep them short in veg, its useless to grow 3 feet of stems that you remove all the branches from.
