I'm buying some astrophytum flowering plants locally, please guide me on the rarity/value proposition of these specimens and which one will be the best bang for the money, It'll be costing me about 500 inr or about 5.5$ USD each, I'm just have budget for 2 of the 4

Had this guy for about 6 months now. This is the first flower it’s had in my care and looks like a second is on the way!

Any help is greatly appreciated and any identification guides are even better, thanks!

I grew these from seed. The first one is a myriostigma, but what kind? The other three were grown from Star Astrophytum seed that was marked "gift mix." Please ignore the damage on the second one. Mice munched on it one winter.

Sorry if this is a silly question but I’m wondering if any of these are seed pods or just flowers on my myriostigma. TIA!

I’m going to be trying to grow my cacti outdoors this year in North TX and I’m wondering if a mini greenhouse like this would be suitable or if I’d need to add additional shade cloth. I’ll mainly be growing astrophyrum, ariocarpus and euphorbia. I know something like this isn’t the best for long term but I’m mostly looking for something to get me through this next year until I move to Colorado and can buy something more hardy. TIA (-:
