Pre-Poured Sterilized Malt Extract Mushroom Agar Plates (10-Pack)
Freshly Poured Daily · Premium Nutrient Blend · Ideal for Spore Germination & Early Culture Work
360° view: healthy mycelium expanding across MEA—perfect for early-stage evaluation.
Looking for the perfect agar plates for fungal culture work? Our 10-Pack of Pre-Poured Malt Extract Agar (MEA) Plates is poured fresh daily and formulated for clean, consistent mycelium development. Made from a carefully balanced blend of light malt extract, yeast extract, locust bean gum, and high-quality agar, these plates are a trusted baseline for spore germination, first transfers, and contamination checks.
Unlike agar plates that sit for weeks before shipping, ours are poured in-house, sealed in polyolefin packaging, and shipped quickly to preserve freshness and performance—ideal for mycologists, hobbyists, and lab workflows that demand consistency.
What’s Included
- (10) Pre-Poured Sterilized Malt Extract Agar Plates – ready to use out of the box
- Professional-grade Petri dishes (clear for easy observation)
- Assorted plate colors to help track batches and add visual clarity
Key Features
- Premium nutrient blend optimized for strong, healthy mycelium growth
- Ideal for spore germination and early culture development
- Consistent, lab-style workflow for repeatable results
- Assorted colors – helpful for organizing plates and tracking freshness
- Storage: refrigerate and use within 3–4 weeks for best results
Machine-Poured for Consistency & Precision
All of our agar plates are machine-poured in our clean room for uniform fill levels and reliable performance. Our process includes:
- MediaPrep sterilization at 18 PSI for 30 minutes
- Cooling to ~145°F, then precision-dispensing 25ml per plate
- UV-C sanitization, automatic capping, and laser labeling
This ensures every plate is uniform, sterile, and lab-ready.
Which Agar Plate Should I Choose?
Different agar recipes perform best at different stages—starting spores, cleaning cultures, spotting contamination, and final showcase transfers. Use this guide to pick the right plate for your workflow.
| Agar Type | Best For | Why Growers Use It | Recommended Stage |
|---|---|---|---|
| Regular LME / MEA (This Listing) | Spore germination, first plates, contamination checks | Reliable baseline media that makes early growth and contaminants easier to evaluate | Start here → first transfer |
| Rapid Rhizo | 2nd & 3rd transfers, clean isolation, showcase plates | Encourages aggressive, threadlike growth patterns that are easy to select and preserve | After first clean-up → final transfers |
| Black MEA | High visibility growth, photo-friendly plates, subtle sector spotting | Dark background increases contrast so mycelium edges, sectors, and early contaminants stand out | Any stage (especially for evaluation) |
| Manure-Enriched / Conditioning Agar | Preparing cultures for bulk substrates, performance testing | Helps “condition” cultures to richer environments and evaluate behavior on supplemented media | Mid-to-late stage (after clean culture) |

Manure-Enriched / Conditioning Agar
Workflow tip: Many growers start spores on MEA, clean up with early transfers, then finish on Rapid Rhizo to showcase final genetics.
Why Use Agar Plates in Mushroom Cultivation?
Agar is a staple in mushroom cultivation and lab culture work. Add a tiny drop of spore solution or liquid culture, incubate, and you’ll see mycelium form—allowing you to select the most vigorous growth while separating it from contaminants.
- Isolate strong genetics by selecting the fastest sectors
- Avoid contaminants by transferring only clean mycelium
- Expand cultures into grain jars, spawn bags, or liquid culture
Agar helps you control your genetics and improve consistency—whether you’re a seasoned pro or just getting started.

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
