Showing some signs of recovery in 24 hours.

Sour D looks a lot better but Snow Cap is slower to respond. Flo somewhere in between.

I'm also looking into a plug n grow igs-220 co2 / temp / rh controller.

I probably cost a few days to a week, but with any luck they will make a full recovery. I'll post pics in a few days

I've never tried to grow in such a small space, looks like it'll be a bit more of a challenge, but a co2 / temp controller should help...
