Ariocarpus seedlings grow with a reasonable speed under the condition of high humidity and soft sunlight as same as any cacti seedlings.
This condition gives rotting problems on seedlings possibly.
The rotting of Ariocarpus seedlings start from the joint of tap root and tubercles normally.

I lift the joint up from the top soil and try to minimize the rotting.

wow, Hanazono, you got so many seedlings. i am in awe. drooling actually. :) :D #-o

i just want to know how did you get so high germination rate.. what type of soil mixture you used, any special treatment you observed as to lighting, watering, etc etc.

thanks and i'll be following your steps.

The freshness of seeds is key of germination rate for Ariocarpus.
Within 1 year from the harvest shows a good germination rate.
Within 2 years will be a acceptable level and 3 years will show a poor result.
I keep seeds in a fridge.
Seeds are harvested from my plants by myself.

I use a heating pad for the germination process.
Potting-mix:
Organic base seed rising mix-1
~2 mm clay grain-1
~2 mm zeolite-1
~2 mm scoria-1
coarse sand-1

Top dressing:
2~4 mm zeolite

Fungicide:
Yes used, spray over potting mix and sown seeds

Temperature:
30 C' at the top of potting mix
There is 3 C' differential temperature between the heating pad and top of potting mix and so I set 33 C' on the heating pad.

Light:
Natural, no artificial light

Germination process time:
2 weeks
The germination of Ariocarpus seeds will complete in 2 weeks.
Seeding pots are removed from the heating pad and moved into a wet-box (plastic box, a capillary mat is laid on the bottom).

Seedlings will be in the wet-box for 2~3 years.
Water over the capillary mat, not over seedlings.

I repotted 70 of 3 years old seedlings, A. bravoanus v hintonii yesterday.
I sowed seeds on 7th August 2013.
Seedings are in 5 cm square tubes.

Thank you for sharing.

Can Ariocarpus be grafted?
Have a good day!

Yes, Ariocarpus seedlings can be grafted.
I graft more than 100 seedlings onto Pereskiopsis stocks every year.

I will start the grafting next month for this season.

It has bee the time of harvesting Ariocarpus seeds.
Some plants have pushed fruits up.

Updated photos for 2 species, taken in this morning

These 2 pads were posted on 27th March 2016.
You can see how much seedlings have grown since.

I made the mistake of thinking that my Ariocarpus seedlings would like it drier and sunnier than most species and they rewarded me by turning rather pink (red). I think it's probably what one might describe as sunburn. They have not grown very much this year as I have still been watering quite sparingly. If I water more generously next year and keep out of full sun do you think they will recover?

I think each person has different opinion but:

Reddish seedlings have received too strong sunlight.
They will stop or reduce the growing speed.
Any seedlings including Ariocarpus need soft sunlight.

I set Ariocarpus to receive softer sunlight compared to Astrophytum and Mammillaria even mature plants.

It is not shown on the seedling photos but each pad has a small shady cover.
The cover is shown on the photo posted on 29th Feb 2016.

Reddish color will recover easily when you reduced the strength of sunlight.

nice seedlings you have there Hanazono.
My experience with growing ariocarpus and astrophytum from seed results in about 2-3 month old seedlings suddenly turning transparent and mushy. Is this too much moisture? thanks
