The strongest of the five.
Marshmallow Shrooms are named for their pale, fluffy fruits. They grow dense and chunky with light, creamy caps, noticeably thicker set than the classic strains, and the kit itself is forgiving and reliable to run.
Where Marshmallow stands apart is potency. This is the strongest variety in our grow kit range, which makes it a poor place to begin and an excellent place to go next. Experienced growers pick it for a deep, vivid and long-lasting experience. If this would be your first kit, Mexican or Golden Teacher is the better entry point.
Maximum strength
Intense euphoria, vivid visuals and deep introspection. A journey of six to eight hours on average.
Complete kit
Grow tray, grow bag with air filter, two sealing clips and a step-by-step manual. Nothing else to buy.
Flushes
After the first harvest the kit keeps producing. The second flush is usually noticeably larger.
From box to first harvest
Four steps, no growing experience and no extra tools. The kit arrives fully colonised, so all it needs from you is the right spot and a little patience.
Set it up
Place the grow tray inside the supplied grow bag and close the bag with the two sealing clips.
Find the spot
A bright place out of direct sunlight, at roughly 20 to 25 °C. A heating mat helps if your room runs cooler.
Wait for pins
Within one to three weeks the first small mushrooms appear. Keep the bag closed and let them develop.
Harvest
Pick as soon as the caps start to open. Then let the kit rest for the next flush, usually a larger one.
Growth speed and yield depend on temperature, humidity and how carefully the kit is handled. The first flush is often a little smaller, the second is usually considerably larger.
Grow your own
A complete Marshmallow Shrooms kit, ready to fruit, discreetly shipped from the Netherlands.
Dosing guide
Magic mushrooms are dosed by dried weight. The fresh equivalent is shown below each amount, as fresh is about ten times heavier than dried. Start low, you can always build up.
No trip. Subtle, for focus and mood.
A gentle introduction to mushrooms.
A clear, visual psychedelic experience.
An intense, deep journey for the experienced.
Dried weights are the most precise. Fresh equivalents are approximate, as fresh weight varies with water content. Effects also vary per person, strain and setting. Choose a calm setting, arrange a sober trip sitter, and avoid alcohol and other substances. This is not medical advice.

Legal & shippable
In the Netherlands, mushroom grow kits are legal to buy and own. The kits contain fully colonised mycelium of the Psilocybe cubensis mushroom. Because no mushrooms (fruiting bodies) are present yet, they do not fall under the prohibited substances in the Opium Act.
Growing and using mushrooms is permitted in the Netherlands for personal use. Grow kits often fall under the Mutual Recognition of Goods Regulation, which means they may be sold throughout the EU if they are legal in one member state.
