Eight species, one chamber, one science-backed growing method. Pick the species that fits your kitchen and skill level, then follow the dedicated growing guide that takes you from block-open to first harvest in 5 to 35 days.
The eight species below are the ones we ship as 5lb fully colonized blocks. Each card links to that species' dedicated guide, where you will find cultivar variants, exact temperature ranges, flush-by-flush yield expectations, and species-specific troubleshooting.
The flagship species. First harvest in 7 to 14 days at 61 to 70Β°F and 87 to 92% relative humidity. Mild seafood-forward flavor that sears like meat, plus the most-researched gourmet mushroom for cognitive support. Pearl Pom is the cultivar most beginners pick.
The fastest fruiter we ship. Pins form on day 2 to 3, and a full first flush usually lands in 5 to 7 days. Tolerates warmer kitchens (65 to 80Β°F) and forgives humidity dips. Best species for someone who wants a quick win in their first week.
Shiitake needs a cold shock to trigger fruiting, then 14 to 21 days at 55 to 75Β°F and 80 to 90% humidity. Slower than oysters, but the umami payoff is the deepest of any home-growable species. Donko (winter-harvest) caps fetch premium prices at specialty grocers.
The cool-weather oyster. Best results in apartments that sit 55 to 70Β°F (basements, north-facing rooms, winter heating off). First flush in 7 to 10 days, and the caps darken to a deep blue when grown at the lower end of that range. Faster than shiitake, more flavorful than pearl oyster.
The species you slice into 1-inch coins and sear like scallops. Fruits in 10 to 14 days at 55 to 70Β°F with low-frequency, high-volume misting. Lykyn block produces 3 to 6 fat clusters with stems thick enough to plate as a vegetarian centerpiece.
An autumn-tasting Italian species with grape-like cluster habit. Fruits in 12 to 18 days at 60 to 72Β°F. Pioppino tolerates the widest humidity swing of any species we ship, which makes it a good second-block choice for anyone who lost a block to dry air on their first try.
Maitake ("hen of the woods") fruits as a single rosette weighing 8 to 24 oz off a 5lb block. 21 to 35 day cycle at 55 to 65Β°F. The longest-cycle species we ship, but the rosette holds shape better than any other and the beta-glucan content per gram is the highest in the home-growable line.
A criminally underrated cluster mushroom. Caps look hand-glazed (the Latin epithet adiposa means "fatty," referencing the cap sheen). Fruits in 10 to 16 days at 55 to 70Β°F. The stems stay crunchy after stir-frying, which is uncommon and exactly why chestnut shows up on high-end ramen menus.
Every species in the list above wants the same four things, just dialed to different settings. Get these right and the species-specific stuff becomes much easier.
Every gourmet mushroom on this page wants 85 to 95% RH during fruiting. Below 80%, pins abort and primordia crust over. Above 95% for long stretches, bacterial blotch sets in. The Smart Chamber holds 92% by default and the Block + Bag method gets you there with 3 to 4 mistings a day. Beginners almost always undershoot humidity, never overshoot.
Mushrooms breathe oxygen and exhale CO2. Without fresh air exchange, CO2 builds up inside the fruiting environment and the mushrooms grow tall, thin, and aborted (the classic "stretch and die"). Open a sealed bag 4 times a day for 30 seconds, or let the chamber's automated FAE cycle handle it for you.
Mushrooms are not plants. They do not photosynthesize. But they do use light as a directional cue. With low-to-medium indirect light (a north-facing windowsill or a 12-hour soft LED), caps form on the side of the cluster pointing toward the brightest source. With no light at all, mushrooms form on every side of the cluster, which is fine but produces oddly shaped harvests.
This is the one variable that changes per species. Tropical-warm species (pink oyster, chestnut) want 65 to 80Β°F. Temperate species (lion's mane, blue oyster, king trumpet, pioppino) want 55 to 72Β°F. Cool-shock species (shiitake, maitake) need a 24-hour fridge stint before fruiting. Match your room temperature to the species and you have done most of the work.
You can grow every species on this page without any device, by misting blocks 3 to 4 times a day. The numbers below are what changes when the chamber does that for you. Source: 12 months of Lykyn customer surveys plus our internal block-replacement data.
