I have a few 2-liter bottles filled a little more then half-way with soil with 2-week old plants growing in them. A couple of the bottles have some algae looking green stuff growing in the soil. Is this bad? The plants look very healthy.

Think the two liters may trap moisture since they are only half-filled... so as water evaporates from the soil some of it condenses on the sides and drips back down back into the soil. I did this on purpose, to give the seedlings extra humidity outside and to protect the little plants from rabbits and squirrles and other animals (they can't reacy the plants down in the two liters bottles).

However, I'm wondering now if this is a bad idea since algae or mold or something is growing in the soil. I plan on transplanting in 2-3 weeks anyway, but I'm wondering if you think I should go ahead and get the plants into larger pots with fresh soil.
