The bigger picture of my Opuntia experiment
Two things I find quite interesting :
(1) The pot on the right had seeds which were exposed to sunlight for an afternoon, the 'flash' method.
On the left the same fresh seed from the same fruit at the same time in the same compost.
The black and brown pots were chosen so that I would remember which was which !
Approx 15 seeds each.
Ok so it is one experiment which will need to be repeated for statistics, but it is suggestive of an influence !?
Should be repeated, not least to eliminate observer bias - such as getting confused about what he was doing and putting all seeds in one pot only ! I was really worried that anno domini had struck when initially none at all came up in the brown pot, so I was mighty relieved when that one seedling appeared proving that I had not gone totally bonkers !
(2) The second thing, , , my puny Opuntia are about 3/4" wing-tip to tip, (4" pot) whereas Tony's robusta are just a tad under 2" !
I think I am a bit late this year to start tephro etc sowings, plus the domestic staff are beginning to raise eyebrows at the proliferation cacti and other succulents Perhaps I'll just buy a mini opuntia plant or two for now lol!
I must soon decide when to prick-out those seedlings, or just nip some off to give room , , , ,
Opuntia seeds - update.

Re: Opuntia seeds - update.
Jest ye carefully .... there's much truth in that. Some seedlings do actively kill off their siblings ... saguarro for one ... so that some growers thin their plants or transplant them on early to maximise the germination.
Endeavouring to grow Aylostera, Echinocereus, Echinopsis, Gymnocalycium, Matucana, Rebutia, and Sulcorebutia. Fallen out of love with Lithops and aggravated by Aeoniums.
Currently being wooed by Haworthia, attempting hybridisation, and enticed by Mesembs.
