01
Closed-loop humidity control
A high-accuracy SHT3x sensor reads RH every 60 seconds. The piezo humidifier pulses on whenever readings drift below your setpoint. Most species sit comfortably between 88 and 92% RH inside the chamber.
Mushroom Grow Boxes
The mushroom grow box that replaces every shotgun chamber, monotub, and humidity dome you have ever tried.
A traditional mushroom grow box is a plastic tote with holes, a spray bottle, and a lot of crossed fingers. The Lykyn Smart Mushroom Grow Box is a 12 by 12 inch automated chamber that holds 85 to 95% humidity with an ultrasonic humidifier, runs a 4-hour fresh-air cycle, and bathes your grow in a species-tuned LED schedule. You set the species in the app, drop in a 5lb fruiting block, and walk away. The chamber does the rest.

Why grow with Lykyn
02
Fresh air without the contamination
Two variable-speed DFH4010S fans exchange chamber air on a schedule. CO2 leaves, oxygen comes in, and the HEPA-style intake keeps competing spores out. This is what stops dry caps and weak pinning.
03
Built for the way you actually grow
The 12 by 12 by 12 inch interior fits one 5lb block or six small jars. Need more space? Add the double-tier extension to stack two chambers in one footprint.
04
Quiet, low draw, dependable
Under 35dB at the fan and ~5W on average. Quiet enough for a bedroom, low enough to leave running 24/7. Add a seedling heat mat if your room runs below 65°F.

What is the difference between a mushroom grow box and a fruiting chamber?
Functionally none, but in practice a grow box usually refers to a finished consumer product (like ours), while a fruiting chamber often refers to a DIY shotgun tub or monotub. The Lykyn chamber is the automated, app-controlled version of what serious hobbyists used to build by hand.
Can I grow more than one species at a time?
You can, but only species with similar fruiting conditions. Oysters all share similar RH and FAE needs and play well together. Mixing Lion's Mane with Shiitake is harder because the temperature preferences differ. Most growers run one species at a time for the cleanest results.
How loud is the grow box?
Under 35dB at 1 meter. That is quieter than most refrigerators. The fans only spin up during fresh-air-exchange cycles, which run every 4 hours by default.
Does it need a separate water reservoir?
The 2.8L ultrasonic tank is built into the base. Most species need a top-up every 7 to 14 days. The app pings you when humidity behavior suggests the tank is getting low.
Is there a temperature control?
No, and that is intentional. Most edible mushrooms fruit happily at typical indoor room temperatures (65 to 75°F). For Pink Oyster runs in cooler rooms, a $15 seedling heat mat under the chamber bumps the substrate into range. Adding a TEC cooler would have doubled the price for marginal gain.
