By now, I would have removed the tape from the dome lids, (icee drink covers), but humidity is running super low this grow. Normally, my little Honeywell humidifier was enough to bring humidity levels at least in the 60s for new seedlings. However, this isn't the case and I suspect it's from running the 3X MarsHydro TS-1000. They are so hot, I'm pretty sure that's what causing the issue, (beside normal winter low humidity). It was running at 16% before I added the 1 gallon Honeywell humidifier, but that only brought it up to 24%. So last night, (after looking at on-line recommendations and reviews), I ordered this from Amazon. I just got through checking and it's only 250 miles away. Maybe it will get here on Thursday as promised.

Hopefully, it will remedy the issue and I can get rid of the domes!
