More about San Pedro 20 seeds
If you do not have much cactus growing experience, the San Pedro is an easy cactus to begin with. They tend to be slightly more resiliant and can handle disadvantageous conditions. Growing cactus from seeds however may always be a bit of a challenge.
Nursing tips:
Fill a small flower pot or container with perforated bottom with standard sowing soil, to about one centimetre below the rim.
Then tamp the earth down gently and place the pot in a tray of water until the top becomes moist.
Next spread the seeds over the surface and give them a quick spray so that they stick firmly to the bottom.
Cover the container with cling film or a lid and place it in a warm, bright place.
be careful with direct sunlight, it can cook your cacti!
For best results, try to keep the temperature around 25ºC and the humidity at 80-90%.
When most of the seeds are germinated, you can carefully start ventilating the plants by poking a few holes in the foil or removing the lid for acouple of minutes every day.
After about 3 months you can let them get used to a drier environment by providing increasingly more ventilation. You can do this by piercing more and more holes in the foil, or by removing the lid a little longer every day. Make sure that the cacti get enough fresh air, but beware that they don't dry out. After about 6 months, they are slightly over a centimeter in size and you can transplant them, this happens best in soil suitable for cacti.
