Peniocereus greggii ssp. transmontanus Agua Prieta seeds will usually germinate in 5-180 days, even under good conditions germination may be erratic. Normally will only germinate with light so surface sow. Sow Peniocereus greggii ssp. transmontanus Agua Prieta seeds on the surface of a Peaty seed sowing mix at about 25°C.
Sand, and loam, with some sphagnum moss or coir (coconut fiber/dust) make a good mix for germinating cacti and similar seeds. The mix needs to be free-draining, and to be slightly water retentive. Surface sow the seeds and just cover with sand. Start germinating the seeds in shady (dark), humid conditions. As the seeds start to germinate, increase the light and decrease the humidity.
