The truffle cultivation set comes with full instructions. You can also find the manual here: https://www.zamnesia.com/content/453-magic-truffle-cultivation-set-manual
Truffles grow underground, so you won't see visible progress on the surface. It can take up to 20 weeks before they're ready to harvest. Patience is key.
If you notice contamination (unusual colours, bad smell) or have no result after 20 weeks, send us a photo and your order number. We'll help troubleshoot.
