First, learn that if you're going to divide a container into different seeds, it will be easier to do 2 similar kinds. (i.e. 2 different petunias or 2 different zinnias).

I would poke more holes in the lids if you haven't already. Move them to morning sun only, less chance of overheating on hot afternoons. Keeping the lids on is beneficial in that it will increase humidity to help germination. Unfortunately it can also cause overheating on a warm sunny day, killing seedlings already present.

I only put one kind of seed per pan. I was just worried about my zinnia pan that has half sprouted and the other has nothing. But I will move all of them to a place that has afternoon shade.

When are the sprouts big enough to seperate out of the HOS? They now have 2 little leaves on them.

Thanks for the response. Every little bit helps!
