About this method

PF Tek (Psilocybe Fanaticus Technique) is the classic hobbyist method: sterilize jars of BRF and vermiculite, inoculate with spores, wait for colonization, then birth the 'cakes' into a humid fruiting chamber.

Spore syringes are legal to buy in the Netherlands. The main investment is a pressure cooker for sterilization โ€” after that, each batch costs only a few euros in materials.

The key skill is sterile technique. Work clean, be patient during colonization (3โ€“5 weeks), and don't open jars early.

  4. ColonizeStore dark at ~24ยฐC for 3โ€“5 weeks until jars are fully white.
