Hey mate, yeah, the possibilities are endless. It definitely has a Super Pedro look to it, so that one were my very first choice if I'd have to pick one.

Hey mate, welcome aboard.

Hey mate, are these different types of seedlings or species or the same? Different species have different growth rates, both in regards to the body and the roots. Then, the soil definitely looks different in structure, which could make a big difference too. Even if it's the same ingredients, their structure might be different or there might be additional add-ons in one soil that aren't visible, e.g. clay dust is often added to improve the root formation. Also, soil pH might be different, which could make rooting easier or more difficult. Position in the greenhouse/garden/environment might play a part too. A spot that's in full sun means less soil humidity and one that's more in the shade would provide more humidity in the soil. Both have effect on the roots. And yeah, nutrient availability or fertilizer composition might be different. For example, I use extracts and fertilizers containing silica because it improves the root formation dramatically. Lots of ways to look into this and hard to tell what the culprit was. Bye Eg

Lovely plant, mate!

Extreme dehydration due to unsuitable soil. The minerals you have there would probably be fine, but it lacks finer ingredients so water runs straight through it. Get some finer Pumice, Lava, Coir and stuff like that and mix it evenly. Roots can't properly form around these huge particles. They are just too loose, and it just makes it very hard for the plants to get a good root system. And ditch the quartz topping layer too. It makes it even harder to judge about the humidity of the soil because you can't check it easily. And yeah, more water and fertilizer in the future. Bye Eg

Hey mate, looks VERY PC to me too.

A greenhouse will be the death of me one day.

Yeah, Opuntia, but really hard differentiating them from just a small piece like this. They can look very similar at this size. Lovely plants though.

Hey mate, first two are Myrtillocactus geometrizans, then a Pilosocereus, then a Harrisia, next two are Myrtillocactus, then Cereus and the last one is a Myrtillocactus that has a massive scale infection. Hope this helps, bye Eg

Hey mate, the Trichocereus pachanoi 'YOWIE' has spines like this!

Hey mate, the overall conventions on how to officially name plants applies to cacti as well. There's no registry that collects and regulates Cactus cultivars, but for a name to be officially recognized as cultivar you need to provide the following things. It's an excerpt from my hybrids book.

Hey mate, first one is probably a clumping Echinopsis Crest. There's Trichocereus candicans crests that look similar but the spines just don't fit for that one. Bye Eg

Hey mate, this is sunburn. The combo of heat and sun was too much for these. I'd put these a bit in the shade so it can heal adequately. Bye Eg

Hey mate, thanks for bringing it to our attention. This needs to be resolved ASAP. Please keep us informed how it goes. Ghosting customers is not a good thing and if we see it around here, we look really closely.

Hey mate, I am not sure if it's actually the case but merging accounts like that might not be supported by the software. I've seen hacks in older versions, but not sure if it's possible in this version. Would definitely recommend bringing it up with Torsten as he knows the software best.
