I gathered about 200 seeds from my various plants. I intended to place them in clear disposable plastic containers (6x6x2) in between wet paper towels. Before doing that, I put each seed in a bowl of diluted Physan20 (1 Tbsp / Gallon). I put about 10 in each container, hence 20 containers). I placed the lid on each container and placed it in the corner (moderate daylight/sun from the window). Every day I looked at the outside of each and could tell that they still adequately wet. I did this about 1 week ago.

Tonight I looked through the bottom of one and could tell that several were sprouting. I opened it to see how they looked and found that two had tiny white fibrous fuzz growing on them (looks like cotton candy, only white).

I'm not sure how to progress here. I'm also not sure if I should preemptively change all 20 containers, or just wait to see if they also get a fungus.

Should I:

Soak these seeds in diluted Physan20 again? If so, how long? I suppose I would then rinse the containers and put in fresh paper towels?

Should I do this now to all 200 seeds?

Or, should I throw them in dirt now?

Any help would be greatly appreciated. I have read most every thread here on how to grow, but I don't recall ever seeing a discussion of fungus.

Sorry about the lack of clarity in the pics - my camera would only focus on the recycling marking or the dishtowel underneath the container.

Thank you so much -- what a relief!
