Just thought I'd share some of my small propagation experiments. I haven't done a ton of propagation, and those that I have done were trial and error with a few decent results. I recently got some growing lights, so I decided to try starting some succulent propagations with them.

I set up a small table where I attached two of the sets of lights. One has four red/blue LED strip lights, and the other has four full spectrum LED strip lights. I ended up alternating the two types in hopes I'd get good coverage over the entire table. I started a variety of leaf propagations and gradually increased the light each day until they were at 12hrs of light daily. Here's my results so far:

Here's the oldest set that's currently under the lights. These ones were originally started in a windowsill, but moved to the light table. I have some graptosedums and Echeveria setosa leaves in this one:

This nice compact plantlet didn't emerge until after the tray was moved underneath the lights. I'm quite happy with how it looks so far:

This tray is the next oldest set, and consists of some random leaf drops I had and decided to experiment with. There's a Graptopetalum paraguayense-variegata, and an Echeveria 'Purple Pearl' that are already well on their way. They rooted and began growing plantlets quite quickly. There's also an Adromischus cristatus and another Echeveria setosa in there.

This tray contains the remains of my Graptosedum 'California Sunset' that some of you will recall from the "Cactus and Succulents Chat" thread. This plant got demolished by someone who decided to trash some of my property, so I gathered some intact leaves to attempt to propagate. Lots of roots emerged quickly. I also noticed tonight that there's a tiny plantlet beginning to form on one.

Lastly, here's some leaves I set aside to callous. These are more 'California Sunset' leaves I found after the initial set. I put these here about two weeks ago. I was surprised at how quickly I got roots from these guys. I'll be moving them to a tray with soil tomorrow. Thumbs up

That's all for now. Anyone else have late-season propagations on the go? Smiling

They are well on their way. Thumbs up

"Perle" started in May:

Here's one that decided to flower (bracts do this some times)

Some plants are crazy with propagation. With this on all I have to do is damage the leaf and new offsets will grow from the leaf. The leaf is still attached to the main plant.

That's neat! Do the plantlets drop off at some point? Or does the leaf need to be removed to separate them?

Have either of you propagated Echeveria 'Black Prince'? I seem to have a lot of trouble with this one. I've tried several times to get a leaf propagation, but every time, I just get a big root cluster, the mother leaf begins to die off, and a plantlet never grows. Is there a trick to these guys?

I have not but it should be reasonably possible given the number of plants out there.

It's weird. Any other Echies I've tried, grew plantlets easily. The BPs just won't take. I'll keep trying though!
