Active Air Liquid Culture Kit
The Midwest Grow Kits Active Air Liquid Culture Kit is a professional-grade oxygenated liquid culture system designed to support faster, cleaner, and more consistent mycelium development. By introducing sterile, filtered air directly into the culture, this system helps maintain healthy, fluid mycelium that’s easier to draw, transfer, and scale—without the dense clumping often seen in traditional liquid culture jars.
Built with reusable, high-temperature components and shipped fully sterilized, this system integrates seamlessly into existing liquid culture workflows and is ideal for intermediate to advanced growers looking to improve consistency, efficiency, and output.
What’s Included
Complete Active Air Liquid Culture System:
- Sterilized 28oz wide-mouth liquid culture jar with dextrose & extra-light malt solution and organic anti-foaming agent
- Reusable lid system with self-healing injection port, 0.22 micron filters, tubing, back-flow valve, hose clamps, and custom fittings
- 3D-printed exhaust loop tube holder to maintain clean airflow routing
- Magnetic stir bar with handheld retrieval magnet
- Hagen Marina 50 (2.5W) air pump
- 24-hour heavy-duty timer for controlled airflow cycles
- 60cc syringe, 16g needles, and alcohol swabs for clean transfers
- Extra replacement filters for long-term use
- Printed step-by-step instruction booklet
Active Air Kit – Jar & Lid Only:
- Sterilized 28oz liquid culture jar (same solution)
- Reusable filtered lid system with tubing and valves
- 3D-printed exhaust loop holder
- Magnetic stir bar & handheld magnet
- 60cc syringe, needles, alcohol swabs
- Extra filters and instruction booklet
- Air pump and timer not included.
Reusable Active Air Lid Only:
- Wide-mouth jar lid with self-healing injection port and 0.22 micron filtration
- Back-flow valve, tubing, hose clamps, and fittings
- 3D-printed exhaust loop holder
- Compatible with most standard wide-mouth mason jars
- Includes complete usage and airflow guidance
How It’s Used
- Inject spores, liquid culture, or an agar wedge through the self-healing injection port.
- Incubate the jar at 76–82°F (species dependent) until visible mycelium appears.
- Once growth is established (typically 5–7 days), activate the air pump to begin oxygenation.
- Continue incubation for an additional 7–10 days with controlled airflow.
- After maturity, reduce airflow to 30–60 minutes every 8–10 hours to maintain activity and prevent clumping.
This system is designed to fit naturally into standard liquid culture timelines and does not require constant monitoring once airflow is dialed in.
How It Works
Traditional liquid culture jars rely on passive gas exchange, which can limit oxygen availability and contribute to slow growth or dense mycelium clumps. The Active Air system actively delivers sterile, filtered air into the culture, increasing available oxygen while maintaining a sealed, contamination-resistant environment.
This controlled oxygenation encourages smaller, evenly distributed mycelium structures that remain suspended in solution. The result is a more workable liquid culture that draws easily into syringes and transfers cleanly to grain or other substrates.
Why Growers Choose This
- Encourages faster and more uniform liquid culture development
- Helps reduce mycelium clumping and hardening
- Produces fluid cultures that are easier to draw and inject
- Supports more consistent grain inoculation results
- Reusable, sterilizable components built for long-term workflows
- Scales easily from single jars to multi-jar setups using one pump
- Ideal for growers refining technique or increasing production efficiency
Let customers speak for us
I have always had a great experience with Midwest products. There delivery time is fast and exactly what I ordered. Not once has my substrate been to dry or have I had any contamination. I only have two tubs going right now but definitely will be expanding soon. Thank you for great products at affordable prices.
...and that is viable liquid culture mushroom spores, enough for lots of microscope work, let me tell you.
I pre-stired the jar to show the floating mycellium after nine days. I've been real conservative on the temperature, not letting it get too high, but still I've got great growth.
Once I saw the successful first attempt, I ordered another 10 ounce kit to arrive shortly.
Hey Midwest, thanks for offering the two sizes of the LC kit. I can feel big time, while using the small kit.
Wish you had stickers so I could rep you.
Been doing some agar-related experiments in this guy along with spawn bag inouculation (which I'm not sure is necessary because I've never had a contamination from a Midwest Grow Kits spawn bag - the 5-grain ones are top doggity!)
Just what I needed. I really like the scale and the folding cover.
I’ve been using them for a couple of years and they have always given me great products and customer service is where they really shine though so if you are just starting out or like me an old hand at mushroom cultivation this is the place you need to be pictured is just one of the sizes and the picture is from a second flush also🤪
This worked perfectly as described. Easy to use and the yields were amazing. I make my own now but still get lazy sometimes and order this.
Enjoy
This thing was beautiful to grow. Exactly as described.
Couldn’t be easier or more awesome of an experience. Highly recommend due to its ease and overall experience. Not to mention the benefits from the fruits. I add dehydrated/ground fruits to my morning coffee for immune boost, anti inflammatory and energy boosting properties. You will be glad you got this one. The price is so cheap and the experience is so worth it. Enjoy
I placed my very first grow in a minitub into the automated ecosphere. It kept humidity and light schedule perfect with FAE on a timer 60 seconds on 3x a day. Fruits were huge and plentiful! Im going to fruit my BRF cakes in there next. Midwest is my main supplier of kits and materials. I have the Ultimate Kit with incubator also. Set it up per instructions and it'll serve you well for a long time!
This my second time ordering and both times have been great! No contamination and a fantastic final product. I will definitely order again.
Your products have been consistent and i get the best results with it..
Thank you for this service..
Came in 4 days
Colonized in 14 days now in fruiting chamber .
Looking forward for fresh turkey tail mushrooms.
I recently bought the Midwest Growers small mushroom monotub 2-pack (amazing price for two). They are perfect size for a colonized block! I am currently growing two shiitake blocks and one king trumpet mushroom block and the tubs make it very easy.
My second time growing. First time I bought two different brands of all in one bags from Amazon. Did not work, they both stalled and never fruited. This little kit was my last ditch effort and I’m sitting here less than 8 weeks after ordering and amazing results
I ordered 2 - 10lb blocks and was a little worried that they were plainly wrapped and different sizes. I weighed them and 1 was 8lbs the other 12lbs so the total was correct. Expanded to the expected volume (picture included of smaller block)
These are the best Monotubs on the market for the price they are built well and I wish I had 4 more lol
