Nice plants and pots

And_Pau_Bri, those wonderful looking seedlings. Great job with them.
Do you have yours in a greenhouse? Very healthy. Yes, the different ingredients can seem to creep up there in cost. Thankfully it lasts along time.

Hi Rick, I've been growing these guys under fluorescent light (T8s, 2 warm white 2 cool white), with 16 hours of light per day. I have one of those 6' metal metro shelves rigged up with lights from when I used to have 50+ orchids.

They look wonderful. What ever you are doing, I would say keep doing it.
Interesting thing. I gave a bunch of seedlings to a nursery fella (has Succulent nursery) about 2yrs ago. I went to his place this summer and he had some of them. They where quite small, but had blooms on some.
Mine of the same age are about 4X their size and still with thick caudex's, but only a few have bloomed to date.
He has exceptional plants.

Looking & healthy plants. Looks like your doing a great job!
