Not a strain for a first outing. MDK belongs to the gnarlier end of the cubensis family — a Penis Envy-lineage isolate known for thick, dense, heavily built fruits that look less like textbook mushrooms and more like something that's been carved. Squat stems, oversized caps and a general refusal to follow the usual growth playbook. Cultivators drawn to it are usually drawn to exactly that.
Performance follows the family pattern. Colonisation tends to be slower and less rhizomatic than the fast, weedy strains, pinning can be sparse, and yields come in weight rather than in numbers — you get fewer fruits, but each one carries considerably more substance than its size suggests. Colouring runs pale through to warm tan, with the dense flesh bruising strongly where handled.
Something to keep in mind: this one is genuinely fussy. It wants stable conditions, clean technique, and a cultivar with the patience to wait out a slow start without fiddling. It's also a name that gets applied inconsistently across sources — what arrives labelled MDK from one vendor may behave quite differently from that of another, so it's worth knowing which lineage you're actually working with rather than assuming.
A little history: Around about the turn of the last century, the Mexican variety became more popular in Dutch smart shops. While producing these mushrooms, the cultivator noticed some abnormalities: every few grows, a massive mushroom would grow, so large that it could not be sold in the shops. Instead of composting it, the cultivator isolated it and, after several grows, took it to his boss and showed him his little project. He told his boss that it was the “King” of mushrooms, coming from “Mexican” heritage but with “Dutch” breeding. Soon it was a staple in every smart shop in the Netherlands.
Storage: Keep your spores refrigerated, not frozen, from the moment you receive them. Pop them in the fridge straight away, and they’ll happily keep for a couple of months and in perfect conditions, even for years.
Remember: All our products are sold for microscopy purposes ONLY; do not try to grow mushrooms with any of our products; that would be illegal and very naughty. While I have your attention on this matter, it is very surprising to learn how many naughty people there are out there. No judging, but I cannot answer any questions about growing mushrooms. It doesn’t matter if you live somewhere where growing is legal; I still won’t answer any questions – please don’t ask. However, if you do ask me naughty questions, I will unfortunately have to add you to my banned list, and you will be unable to enjoy any of my lovely products. I will also inform Santa about your naughty behaviour and ask him to put you on his naughty list – that’s now Christmas stuffed. So please, no naughty questions.
Don’t Forget:
Keep them in a cool, dark place; about 5’c is nice
Keep the product in a clean and tidy place
Don’t let the product get hot
Don’t let them freeze
Don’t let them become dusty or dirty
