I have just recently moved them to a north window. I had them on a coffee table with a lot less light. I don't have lights. I recently repotted these into one larger clay pot. I put a lot of styrofoam on the bottom and used fine bark, some perlite, some sphag and some oak leaves. The roots were okay, I had them in individual clay pots before that were deeper than I have them now. The medium is about 3 inches deep. I have taken some pictures for you. The first one is with flash, the rest have no flash so you can see the light at 7PM. It gets a little brighter during the day, duh, but no direct light.
I just watered them today.
I hope this helps.
