Seems healthy to me, but it has been more than a week and it's not growing, still 2cm. Thought it was the humidity so i raised it to 80-90% with 28-29C°. I see a VPD chart and seems right, any guess? Thanks
If your diary is correct, you have a mistake in the light hours!
It says you’re at 12/12, when you should be at 18 hours of light and 6 of darkness.
If that’s the case, that’s the main reason why your plant is NOT growing.
On the other hand, place the lamp at the distance and the % of the dimmer that the manufacturer indicates for this.
Go to the official Mars TS1000 page and you’ll find it very easily.
Good luck and ask whatever you need!
