Hi

ive got 1 astrophytum myriostigma (large)

and many Echinopis (unknown hybrids - one type yellow and one type pink)

im looking to swap pollen of these as im not getting seed

Ive been collecting on cue tips then storing in plastic in the fridge.

I may also have pollen for

Astrophytum crassipinoides

Gymnocalycium gibbosum var nigrum

and other gymnocalyciums again later in the season

Im interested in Trichocereus-Echinopsis hybrids

does anyone have experience here?
