So I'm sad to say those were indeed fungus gnats whose larvae ate half of the seeds, the other half was replanted into a recovery pot. I waited almost a week for the germinations to find out.

Anyway, I will try again, fortunately I still had seeds from the same batch altought they we not the best seeds Before planting them I used the hidrogen peroxide technicque to kill the larvae (1:5 3%HP to water) then I used the sand over the surface to prevent any further infestation and gave it a few hours while I soaked the seeds before planting them.

I still see some fungus gnats but they do seem confused about the sand, hopefuly the HP took care of the larvae and these are just the ones that were wondering around the room.

Fingers crossed for attemp #2...
