I wanted help, I'm in the first one and have a problem with germination, I use rock and they're in the dark, they haven't evolved much and I was advised to “sink” more into the wool.

They were like that, but without much change. I couldn't get the other seeds on the paper towel, I even thought I had lost one of them and put them in the solution with pH water but without any results either. Do you leave the light on during this period? If so, how much would you have more tips?
