The Hollandia Truffle was bred by the largest Dutch growers and was therefore proudly named Hollandia.
This strain contains up to twice as many active substances compared to other types, so it can be overwhelming for inexperienced users. It is therefore not recommended to ingest more than 7,5 grams at a time.
First effects are likely to be felt after around 15-30 minutes and can last somewhere around 6 hours.
You can eat Truffles or use them as a tea (let it simmer for 20 minutes, don't let the water boil).
BE AWARE that these amounts are averages and can vary from person to person. Always start with a low dose.
