Green stuff on surface of soil in indoor garden?

I have a small, lighted indoor garden...I'm growing marigolds in these long planter things, and in a few of them I noticed some green stuff on the top of the soil...it looks almost like moss, but it's more slimy and doesn't stick up like moss fibers do (it's not thick or anything). The stuff looks slimy almost, but it's very green like moss. It kind of looks like algae? The plants are in temperatures ranging from 85-105 degrees F (obviously) with light constantly on. I mist them heavily a few times a day to get temps down. Does anyone have ANY idea what the green stuff might be? And why it's only in a few of the planters? Is it harmful or should I not worry about it? I might upload pictures later if you're not sure what I'm trying to describe so let me know if you need pics and please check back later. Thanks.

1. You could be growing mold along with your marigolds. It likely is caused by the frequent misting. There may be different soil in some of the lanters, or there may be better air circulation around some. Maybe add a fan if it gets too warm.
2. its a mold/contaminating your soil. You'll have to replace the soil and thoroughly clean your containers and make sure none of the green gets transferred on plants (if these are starter containers) - I would just monitor them unti its time to replant. My guess is that you are creating a hot, humid environment and that's the cause. I've had the same problem with some plants that are in front of the hot, southern exposure in my home. Good Luck
