B+ is the pragmatic fast cubensis growkit: minimal drama, maximum usable yield indication, and the same 1800 ml setup as the rest of the range — perfect if you prefer specs over stories.
Why B+ keeps selling on the EU market
EU buyers know what a growkit is. They want strain name, volume, pace, delivery time. B+ scores on speed and robustness without the niche complexity of PE- or TAT-lines. That makes the kit a reliable workhorse next to experimental strains like Timbit or MVP.
Hard specs
Psilocybe cubensis, strain B+, 1.1 kg / 1800 ml, 23–25 °C, 250 g+ indication. Those are the numbers you use to compare Mexican or Golden Halo side-by-side in your log.
Freshness: Poland → EU
Short 3–5 business day transit from Poland is part of the quality claim: less dehydration, fewer temperature extremes on the road. For experienced buyers that matters as much as the strain label.
Legal and transparent
Mycelium is not a controlled substance in most EU jurisdictions — that gives you a clearly defined product. Combine it with strict hygiene and you have a reproducible baseline strain in your collection.
The growkit contains mycelium, which is not treated as a controlled substance in most EU jurisdictions. Cultivation of fruiting bodies containing psilocybin is regulated in most countries — legal status varies by jurisdiction, so verify local laws before handling.
