B+ FreshMushrooms Mushroom Grow Kit 1200cc

B+ Mushroom Grow Kit – FreshMushrooms 100% Mycelium

The B+ is one of the most popular and versatile Psilocybe cubensis varieties in the world. This strain owes its name to its excellent performance: reliable, forgiving and suitable for every experience level. The FreshMushrooms 100% Mycelium grow kit makes cultivating B+ mushrooms easier than ever.

Characteristics of the B+ strain

The B+ produces remarkably large mushrooms with broad, bell-shaped caps that range from light brown to caramel coloured. The sturdy stems can reach lengths of 15-20 cm. This strain is known for its consistent growth and high yields, even under less than optimal conditions.

With a strength of 3.5 out of 5, the B+ offers a balanced experience. The effects are described as warm, visual and creative, without the intense peak moments of stronger varieties. This makes the B+ particularly suitable for beginners taking their first steps, but also for experienced users who want a reliable, pleasant session.

Why choose 100% Mycelium kits?

With traditional grow kits, you must wait until the substrate is fully colonised. FreshMushrooms kits are different: the entire substrate is already grown through with active mycelium. This means you can start immediately and see results faster. The first mushrooms often appear within two weeks of activation.

What's in the kit?

Each FreshMushrooms B+ grow kit contains a fully colonised 1200cc growbox with 100% mycelium substrate. You only need a grow bag, water and patience. The kit can produce between 4 and 7 harvests (flushes) when you follow the instructions correctly.

Growing conditions

Place the kit in a spot with indirect light and a stable temperature between 20-25°C. Keep the substrate moist but not soaked. Ventilate the grow bag briefly each day to allow fresh air in. After each harvest, you can reactivate the kit by submerging the substrate in cold water.
