I totally hear you about the watering and the roots being toward the top or bottom. What I don't know is how to know how deep their roots are at this point. I think my soil looks pretty good and still looks like there's some moisture left. I don't mean that I want to water today or tomorrow, but maybe whenever my new meter comes which will likely be Monday or Tuesday next week. That way I can do another Slurry Test, because that was kinda fun, lol, and to see if they are ready to start receiving Nutrients again. That is one of my big worries right now, because the container says to feed even when they are seedlings, at a 50% recommend amount. I don't know how to know when to start feeding. I imagine there's some test I'll have to do, probably with a meter I don't have. Lol! But yeah, that's a worry inside of my head right now.
Here are my readings in there after just an hour of the tent being sealed back up. Quite an increase of humidity and the heater is still running so that temp should be well up by the time 430 comes and the dark comes. -WeebleK
