I've got some purple, white and pink Hibiscus seedlings going in my greenhouse. I'm unsure if these are hardy or tropical. As shown in the photo below when should I take these and place in starter pots?

Generally you can transplant after your seedling get their first set of "true" leaves. Your just have their cotyledons right now so you should give it a little more time.

Chris you might want to cut back a bit on the watering .. looks like you're starting to grow some algae in the pots.

Anne, I'm just misting them twice a day with distilled water and Epson Salts. The starter mix tends to dry out pretty quickly in the greenhouse when it warms up in there. Should I just go to once a day?

If it's only the very top of the mix drying out then I'd cut back a bit. From the pictures it looks like the mix in those cups are pretty moist going deeper.

I'll do that Anne, I wonder if I can add the algae remover that I put into my orchid humidity pans to the spray I use for the seedlings? Think it would hurt them?

Algae remover can harm or kill plants, so I would not risk it. The algae is not going to harm you plants, it just a sign the you soil is moist and get good light. You want your soil to be moist, just not wet or to dry. It's kind of hard to tell in the photo, but to me the soil in the cups looks moist at the top 1/4 to 1/3 and dry in the lower areas. You say that you are only misting them, so I'm guessing that the water is not penetrating to the lower areas of the containers were the roots are going. I would make sure you have excellent drainage in the pots and add enough water to penetrate to the bottom, then allow it to start drying out to water again.

Ah, thanks Jay, that is more than likely my problem then as to why I have some failures instead of all success. I'll give that a try then. Appreciate the feedback.
