Baby obesa : other way around.
Avonia : 4 grit to 1 JI2.
Water the dry mix with rainwater, microwave and cool.
When cool, in with the seeds (forbies buried to 5mm or so, small cactus seeds on the top), spray on chinosol solution, then a layer of dry clean sand, and some more chinosol solution to wet it all. More sand for larger seeds and none for tinies, eg. Avonia.
Into the baggie, and keep an eye out for mould and the top layer drying out. If it does, I add sterile rainwater with a dropper.
Opuntia are in a wet paper towel in a bag, and a spraying of chinosol. I change the towel every month or so as it goes a bit smelly.
When big enough to handle they will go into standard cactus/mesemb mix. If I pot them up when they have only just germinated, they don't always come up so I leave them in the paper until they are about 1-2cm long.
They will all go on the windowsill unless the sun is directly on them. Obesa, Avonia and Gymno amerhauseri which is a shade lover, get put the other side of the curtain in the shade, Opuntia, mamms and notos take their chances behind the forby shades (stick-on car window sun shades).
No propagator.
Sowing in early May.
, particularly Gymnocalyciums, Rebutias, Sulcorebutias, Echinopses, Thelos, Feros and Mamms (and anything else I like the look of!) all in an 8 x 6 polycarb greenhouse and a few windowsills!
