01
Set it and grow
Pick a species in the Lykyn app, drop in your fruiting block, and the chamber handles humidity, lighting, and fresh-air cycles. The 2.8L ultrasonic tank lasts 7 to 14 days between refills depending on species.
Mushroom Grow Kits
Everything you need to grow gourmet mushrooms indoors, in one quiet 12 by 12 inch chamber.
A Lykyn mushroom grow kit pairs the automated Smart Mushroom Grow Box with the sterile work tools serious growers reach for. The chamber holds humidity at 90% and fresh-air-exchanges on a schedule you set from your phone. Pair it with our pre-colonized 5lb fruiting blocks and most growers see their first harvest in 5 to 14 days, depending on the species. No daily misting, no contamination guesswork, no clumsy DIY rigs.

Why grow with Lykyn
02
Built for repeat harvests
Most blocks fruit twice. After the second flush, swap the block, wipe the chamber, and start the next species. Subscribe to fruiting blocks to keep the cycle going at 15% off.
03
Honest about what we are not
Lykyn is humidity, light, and fresh-air control, not climate control. Cold rooms below 65°F (18°C) benefit from a small seedling heat mat under the chamber. The power adapter is not included, and Wi-Fi is 2.4GHz only.

Bone White or Obsidian Black, glass front, polycarbonate side panels. Quiet enough for a bedroom shelf, beautiful enough for the kitchen counter.

Do mushroom grow kits work?
Yes, when the kit pairs a clean, humid environment with a properly colonized block. The reason most DIY grows fail is dry air and contamination. The Lykyn chamber holds 85 to 95% humidity automatically and exchanges air on a 4-hour cycle, which is why our pre-colonized blocks fruit reliably for first-time growers.
How do mushroom grow kits work?
A grow kit gives you a substrate that is already colonized with mushroom mycelium. You move it into a fruiting environment (high humidity, fresh air, soft light), and the mushroom forms pins within 3 to 7 days, then doubles in size every 24 hours until harvest. Our chamber automates the environment so you do not have to mist by hand.
Can mushroom grow kits be reused?
Each Lykyn fruiting block typically produces 2 flushes, sometimes 3. After flushes slow down, the block is spent. Swap in a new block, wipe the chamber's interior with a 70% isopropyl wipe, and start the next species. The chamber itself lasts for years.
Do mushroom grow kits expire?
Sealed fruiting blocks store for about 90 days in a cool, dark place before they want to start fruiting on their own. Once you open a block and place it in the chamber, expect first pins within 5 to 14 days depending on species.
Are mushroom growing kits worth it?
If you have tried growing mushrooms from a bag in a closet and lost the grow to dry air or contamination, yes. The Lykyn chamber is the difference between a hopeful one-off and a repeatable habit. Most growers recoup the chamber after 4 to 6 blocks of culinary mushrooms vs grocery prices.
When should I harvest mushrooms from a grow kit?
Harvest just before the caps fully flatten and the edges start to curl up. For oysters and Lion's Mane that is usually day 5 to 7 after pinning. Twist the cluster gently at the base, never cut, so the block stays clean for the next flush.
New to growing? Start with a Pink Oyster block for the fastest first harvest. Already comfortable? Add a Still Air Box and move into liquid cultures to expand your own genetics.
