I have 1000 more in my yard I can send youFirst time collecting in the fall. Dug up this Siberian Elm seedling.
You may be drawing too power for the Inkbird. When I was researching thermostats four years ago that was what seem3d to be the issue.I'm constantly checking the temps in my shed. First year with this setup and it's an improvement over the cheap greenhouse, but my temps are still dropping down to 28℉. I am going to look at more powerful heaters or some of those large heated mats for melting sidewalk snow. I have an inkbird powerstrip for better temperature control, but finding a heater that works with the strip is a different story.
