Still Air Box

Create a Sterile Workspace Anywhere

If you’re serious about mushroom cultivation, sterility is everything. A clean environment prevents contamination and gives your projects the best chance of success. The LYKYN Still Air Box is made for mushroom growers. It creates a stable, closed space that limits airflow. This helps keep out contaminants, allowing you to focus on precision.

Whether you’re inoculating grain spawn, pouring agar plates, transferring liquid culture, expanding colonies, or preparing monotubs, the LYKYN Still Air Box gives you the control you need to take your growing to the next level.

Why Choose a Still Air Box?

When working with spores or cultures, you have two main options: a laminar flow hood or a still air box. Flow hoods are powerful but expensive and bulky. A still air box offers the same essential sterile environment at a fraction of the cost, making it the perfect solution for both beginners and advanced cultivators who want portability and simplicity.

Designed for Mushroom Cultivation

• Angled Viewing Panel – Positioned above the dual arm ports so you can see your work clearly and make precise movements.

• Ample Workspace – At 3 ft wide, 2 ft tall, and 2 ft deep, there’s plenty of room for grain bags, agar dishes, jars, and larger projects.

• Dual 9” Arm Ports – Adjustable with cinch straps for a secure, comfortable fit while keeping contaminants out.

• Cord Port Access – A dedicated 4” cinch-sealed port allows you to run electrical cords for tools and equipment inside the workspace.

• Easy Access Doors – A 14” x 19” side zipper door and a 27” x 17” back zipper door make loading and unloading effortless.

Benefits at a Glance

• Restricts airflow to reduce exposure to spores, bacteria, and microorganisms.

• Provides a stable, sterile environment for every stage of mushroom cultivation.

• Large, ergonomic workspace designed specifically for growers.

• Lightweight, portable, and easy to clean between sessions.

⚠ Safety Note
Never use open flames or heat sources inside a still air box. For sterilization, rely on alcohol sprays (70% isopropyl) and proper sanitation practices.

Frequently Asked Questions

What is a still air box used for?

A dead-air workspace for sterile cultivation tasks. Inoculating grain, working with agar plates, transferring liquid culture, and any step where airborne contamination would ruin the grow. The enclosed space stills the air enough that dust and spores settle out of the working area.

Do I need one to grow mushrooms at home?

Not for fruiting block grows. Lykyn fruiting blocks arrive already colonized, so the sterile step is done at the lab. A still air box becomes useful when you move to liquid culture, grain spawn, or making your own substrate from scratch.

How is a still air box different from a laminar flow hood?

A still air box has no active air filtration; it simply blocks room airflow so dust settles. A laminar flow hood actively pushes filtered air across the workspace. The still air box is cheaper, requires no power, and is enough for most home growers moving beyond fruiting blocks.

How do I clean the still air box before use?

Wipe every interior surface with 70 percent isopropyl alcohol or a 10 percent bleach solution and let it dwell for at least ten minutes. Rinse with distilled water if you used bleach. Repeat cleaning between every session; contamination compounds fast in an unwiped box.

Can I use it for grain-to-grain transfers?

Yes, this is one of the primary uses. Sterilize the exterior of both jars, place them inside the box, wait five minutes for the air to still, and make the transfer with gloves and a flame-sterilized spoon.

What size fits inside a Lykyn grow chamber?

The still air box is intended as a standalone workspace, not something you place inside the chamber. Its footprint sits on a countertop and gives you room to work with several jars or plates at once.
