Green? That may not be mold, but good old algae slime. which is produced under more than adequate light & moisture. It often happens when attempting to germinate CP seeds. If it is thick enough, you can manually remoce it with tweezer or by flooding the pots, causing the slime to float. Can you see the seeds to remove them. If none of these can be done, you may have to live with the slime for awhile, until the seedlings are big enough to be removed. While algae slime is unsightly, undesirable, and CAN be hindrence to cultivation, it isn't a major one. There might be other suggestions as well.
