could #8 be parodia microsperma?

Looks like the Terschekiis Ive seen. it definantly falls into the Terscheckii, Werdermannius, Pascana catagory of Trichs. I have one but its only a small seedling although noticeably beefier than my pachnoi/peruvianus seedlings. it could be a cutting or the thinner older portion has been repotted be...

I think ultimately you just have to experiment and find out what works best for you since everyone lives in different climates and has different watering habits. I messed with a lot of different ingredients before I found something I really liked although like most people here I change it up a bit d...

Where's Dean at? Shouldn't he be in here telling us half these names are no longer valid?

One of my favs. 'Blue Candle' myrtillocactus geometrizans but it looks like the tip has etiolated from lack of light.

Thanks Joel. I don't have any recent pics but if I can remember to take some this weekend ill post them. I was going to update in the spring.

I'd love to see an update when it gets larger just to see how it turns out!

Is this a common cactus?

Very common. It's #1 on the top 10 ID requests page.

What Tony said. I have a feeling that is not a Myrtillocactus though.

How about that one at the top right? Don't myrtillocactus seedlings look like that?

Haha... sounds like an adventure. How big is the whole plant?
