Grow mushrooms the easy way – no green thumb needed
Pop the tab on the box, slice an “X” in the bag, give it a quick mist a few times a day, and boom—fresh King oysters in about 3 weeks. It’s basically fool-proof and beginner-friendly.
Tastes amazing & good for you
King oyster mushrooms are rich, nutty, and silky smooth—chefs love ’em for a reason. They also carry a delicate almond-like aroma, and their thick stems cook up with a tender, abalone-like texture. Bonus: they’re low-cal, packed with plant protein, and totally veg-friendly. Perfect for healthy eaters, foodies, and anyone who wants guilt-free flavor.
Big harvests, multiple rounds
Each block is sterilized and fully colonized, so it’s ready to crank out mushrooms. Expect 3–4 flushes with over 2 lbs of fresh mushrooms in total. Just soak the block after each harvest and let it do its thing all over again.
Fast results you can actually see
This isn’t one of those “wait forever” kits—most people see little mushroom pins in 10-15 days. They grow crazy fast, and watching them double in size overnight never gets old.
Made with care, built to perform
We mix hardwood sawdust with natural grains and blast it in the sterilizer hotter and longer than industry standards. That means cleaner bags, fewer headaches, and a way better shot at monster flushes. All packed up in California and ready to grow.
