A grow bag makes growing your own mushrooms as simple as it gets. The substrate is already fully colonised with mycelium, so there is nothing to activate or mix. Still, it is the strain and not the bag that shapes the experience. One is mild and social, another is potent and immersive. Below you will walk through the seven strains we carry, from accessible to intense.

What is a grow bag?

A grow bag is a ready-to-use cultivation bag with substrate that the mycelium has already run through. The moment you place the bag in the right environment, fruiting begins. That means fewer steps and less chance of mistakes early on.

The difference with a classic grow kit is the activation step. With a grow kit you rinse the mycelium, let it rest and then start fruiting. A grow bag skips that step. Find more ready-to-use sets in our grow kits, and separate materials in the growing supplies.

Accessible strains to start with

B+

B+ grow bag, Psilocybe cubensis

The B+ is one of the best-known cubensis strains in the world and has a reputation for being forgiving to grow. The mushrooms are large and robust, with thick stems and broad caramel-coloured caps. The effect is warm, positive and uplifting, with gentle visuals and a comfortable clarity. A logical choice for your first grow. View the B+ grow bag.

Golden Teacher

Golden Teacher grow bag, Psilocybe cubensis

The Golden Teacher is a classic with golden caps and sturdy stems. Its potency is moderate and predictable, and the experience is balanced and reflective. Many people value the clear, insightful moments. Pleasant when you want a calm start. View the Golden Teacher grow bag.

PES Amazonian

PES Amazonian grow bag, Psilocybe cubensis

The Amazonian colonises strongly and delivers a generous yield with firm, well-formed fruit bodies. The strain is known for reliable results and multiple flushes with good care. The effect is moderate. A rewarding choice for a full harvest. View the PES Amazonian grow bag.

Hillbilly Pumpkin

Hillbilly Pumpkin grow bag, Psilocybe cubensis

The Hillbilly Pumpkin comes from the Hillbilly lineage, with rounded, sometimes flattened caps in a warm orange hue. The strain colonises quickly and produces dense clusters. The effect is moderately potent and described as light, social and mood-enhancing, with a gradual build. Nice for calmer, shared sessions. View the Hillbilly Pumpkin grow bag.

Stronger strains for the experienced grower

Blue Magnolia

Blue Magnolia grow bag, Psilocybe cubensis

The Blue Magnolia is a relatively modern variety with robust mushrooms, thick stems and medium to large caps. Growth is stable and yields are consistent. Its potency profile runs from moderate to above average, with an immersive experience, vivid visuals and enhanced auditory perception. Start with a low dose. View the Blue Magnolia grow bag.

Blue Ghost

Blue Ghost grow bag, Psilocybe cubensis

The Blue Ghost is an albino-dominant hybrid, created from a cross of Long Ghost and Blue Shakti. The caps are milk-white to light golden, with sturdy stems that bruise a striking blue when touched. That blue discolouration comes from the oxidation of psilocybin. It is accessible to grow, but the potency runs from medium to high. Start carefully. View the Blue Ghost grow bag.

Yeti

Yeti grow bag, Psilocybe cubensis

The Yeti is a well-known albino variety, thought to be derived from the True Albino Teacher, although this has not been formally confirmed. The mushrooms are thick and pale with a white to bluish colour. The strain needs slightly more attention during cultivation and is above average in potency. The experience is intense and immersive, with strong visuals. Best suited if you already have experience. View the Yeti grow bag.

Which grow bag suits you?

If you are new, the B+, Golden Teacher and PES Amazonian are pleasant starting points: mild, predictable and easy to grow. If you want something more social, choose the Hillbilly Pumpkin. If you already have experience and want more depth, the Blue Magnolia, Blue Ghost and Yeti offer a stronger experience. With every strain the cultivation is ready to grow, the difference is in the strength and the character of the trip.

How to start growing

Place the bag in a clean, well-lit spot out of direct sunlight, at room temperature. Follow the included manual step by step for opening, humidity and harvesting. Our magic mushroom grow bag manual explains exactly how to get the best yield. Keep an unused bag refrigerated at 6-8°C, and it stays good for up to 6 months. Do not freeze.

Safe use

Magic mushrooms are for adults aged 18 and over only. Start with a low dose, especially with a strong strain or if you have little experience. Make sure you are in a familiar environment with a sober trip sitter present. Never combine with alcohol, antidepressants (SSRI/MAOI) or other substances, and do not use if you have a personal or family history of psychosis or schizophrenia. Pay close attention to set and setting. Find more background in our knowledge base.
