1 month Update:
I'm starting to see activity.
I got a feeling I might be overrun/overwhelmed with a bulk supply of ferns next year!
Close-up I can see what appears to be a green start, surly not mold. I keep the lids sealed all the time. Table/heat-mat plants are on is limiting water/slowed down. Water is reaching roots only once every couple weeks, lowest I will let GH get is 50F. Still getting up to 100F w/ daylight. We'll see what happens.
