how to reduce algae growth on surface?
What do you to to prevent green algae from growing too much on the surface of potting mix? What do you spray on the surface and not harm the seedling and germination rate?

10 percent solution of home use hydrogen peroxide and water in a spray bottle might help and it won't hurt the plants.
It will also stop damping off.

I usually cover seeds in vermiculite to sprout them, and then having the top layer of media be loose and dry helps against algae. Perlite or sand would be similar. And bottom watering also helps.

I always take algae as a sign it's too acid - sprinkle of lime works.
