HI,
I put mine on the reservoirs immediately.

I have a semi related question: if you have bagged leaves (I have some bagged, some domed), should you take the leaf out of the bag as soon as it has offspring? Or leave it in the bag until the offspring is large enough to remove?

As in all things, I imagine people do it both ways, but interested in hearing why people do what people do and the results they get.

I leave the leaf and offspring in the bag until I want to remove the baby or babies (if some babies aren't big enough to remove but others are, I leave the smaller ones attached). I pot the babies in a 2 oz condiment cup, and put each one back in a new baggie. I put the leaf back in its baggie to keep making plantlets, if it wants to. I let the babies grow on until they are a fairly established size (big enough for a 2.5 inch pot) and pot them up. This is when I finally let them out of the bag. This ensures that the plantlets survive for me. The 2 oz condiment cups are a good size for the plantlets but dry out rapidly, and I can't keep up with the watering schedule for these, so keeping them in the bag is the only thing that works for me. I haven't lost any to rot, but I don't water them frequently at all. They grow rapidly in the bag. I keep them under lights now. I have put them in the window before, but I got tired of looking at baggies instead of plants; it felt like I was growing plastic baggies, especially since they did seem to multiply! (This would happen when I got new leaves, or separated babies into their own space.)
