Maybe I should sow and keep these outside the bag in the future. Start letting the pot dry sooner too. The high humidity doesn't seem to improve germination anyway..

That's too bad! Let me know if you want to try again, I recently pollinated my Strombo disciformis and hopefully will have lots of seedMrXeric wrote: ↑Tue Mar 29, 2022 8:29 am
Strombocactus disciformis: Last November I noticed that the seedlings were completely drowned by green algae, though their round shape was still discernible. I spray the pot with hydrogen peroxide, but the algae was persistent so I took the pot out of the bag and let it dry. Over the next several weeks, the seedlings slowly flattened and damped off until all were gone.
Yes seedling of Strombocactus disciformis is very small and grow very slowly.Strombocactus disciformis: Last November I noticed that the seedlings were completely drowned by green algae, though their round shape was still discernible.

Great looking seedlings, Frank. Certainly slow though!Hanazono wrote: ↑Sat Apr 02, 2022 9:26 pm Yes seedling of Strombocactus disciformis is very small and grow very slowly.
I sowed seeds on 13th November 2018.
Repotted them into 10 cm square pots on 8th October 2019 and 1st Feburary 2020, 100 seedlings in total.
92 seedlings have survived. Large one is 17 mm and small one is 10 mm in diameter.
Not quite what I was expecting, but if my seedling eventually look like the listing picture I'll be happy! Also, I think some of the seedlings are variegated? The middle seedling has a color gradient of white at the base, turning to yellow going up, and green at the apex. Hopefully not diseased?Yes there was an error when the label was transcribed. 827 had 822.7 seeds in the packet. So unfortunately if you bought 827 it was not the right seeds but now everything is set correctly, 822.7 has the right picture, name and data.
Thanks keith! I am making a list of all the seeds that failed last year and this year to retry next year. Just waiting to see what gonna fail for this year's sowing..but I'll keep your offer in mind, since it seems mesa doesn't have the albiflorus seeds anymore? last time I checked anyway. Maybe by then I'll have something to trade with you.keith wrote: ↑Wed Apr 27, 2022 1:34 am Turbinicarpus valdezianus v. albiflorus I have seeds of these if you want to try again. Sold by Mesa as "Lobivia haematantha v. rebutioides" I sowed these also I had poor germination maybe 2 are up hard to tell germination so bad I combined a bunch of other Mesa seedlings plus some of my own seeds.
Your small seedlings look good you have some hard species .
I sowed seeds of T. valdezianus v albiflourus before and the germination rate was very good.Turbinicarpus valdezianus v. albiflorus SB 205 Santa Ana, Nuevo Leon, Mexico [MG1302]. Only one seed tried to germinate, but it never made it past the radicle poking through the seed. Tried drying and rehydrating, but I eventually gave up and threw out the pot.
