Pre-Poured Sterilized Malt Extract Agar Plates (5-Pack)
Freshly Made Daily · Assorted Colors · Ideal for Spore Germination & First Transfers
360° view: healthy mycelium expanding across MEA—perfect for early-stage evaluation.
Get reliable, repeatable growth with our Sterilized Malt Extract Agar (MEA) Plates. Each 5-pack is freshly poured and sealed the same day, delivering the clean, consistent performance you want for spore germination, contamination checks, and first transfers.
Formulated with a balanced nutrient blend—including agar, malt extract, locust bean gum, and yeast extract—these plates support vibrant, healthy colonies from the very first plate. Unlike pre-poured agar that sits on shelves for weeks, our MEA plates are produced daily and sealed in polyolefin packaging to help lock in freshness.
What’s Included
- (5) Sterilized MEA Plates – pre-poured, ready-to-use
- 90mm polystyrene Petri dishes (professional-grade)
- Assorted / color-coded plates to help track batches and add visual clarity
Key Features
- Excellent for spore germination and early-stage culture work
- Balanced nutrition for clean, steady mycelial expansion
- Machine poured in a clean workflow for consistent fill and repeatable results
- Green, Blue or Pink colors – Randomly chosen and helpful for organization and quick batch ID
- Storage: refrigerate and use within 3–4 weeks for best results
Lab-Poured Precision, Every Time
All of our agar plates are machine-poured in our clean room using advanced MediaPrep and MediaFill systems:
- Sterilized at 18 PSI for 30 minutes
- Dispensed at 25ml per plate
- UV-C treated, capped, and laser-labeled for accuracy and consistency
Which Agar Plate Should I Choose?
Different agar recipes shine at different stages—starting spores, cleaning cultures, spotting contamination, and final “showcase” transfers. Here’s a quick guide:
| 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 when evaluating detail) |
| Manure-Enriched / Conditioning Agar | Preparing cultures for bulk substrates, performance testing | Helps “condition” cultures to richer environments and evaluate how genetics behave on supplemented media | Mid-to-late stage (after clean culture) |

Workflow tip: Start spores on MEA to evaluate cleanliness, transfer clean sectors, then finish on Rapid Rhizo when you’re ready to showcase your strongest genetics.
What Is Agar? How Do I Use It?
Agar is a vital tool in modern mycology. Add a tiny amount of spore solution, tissue, or liquid culture to your plate and incubate. Within days, mycelium begins to spread—allowing you to select clean growth and separate it from contaminants.
Using agar allows you to:
- Identify and isolate clean, strong genetics
- Spot contamination early before it reaches grain or substrate
- Improve consistency and reliability across grows
Whether you’re a seasoned mycologist or just starting out, fresh MEA plates are one of the best foundations for successful culture work.

Let customers speak for us
I ordered 7 altogether so far, and every single one worked faster than expected. As you can see from the pics I got crazy growth in just 5 days from all of them!
I absolutely love the 28 quart monotubs. It lets me have 2 different grows going and since I'm a beginner, that helps in case one tub get contaminated or something goes wrong with one. I will still have a backup! Happy Growing! I know I am!
So far, I have no complaints. Everything was delivered on time packaged with care. I got everything set up now, i'm just crossing my fingers and hoping everything crosses the finish line.
10 pounds black cow casing, 3-32oz 5 grain jars fully colonized in mono-tub. Completely covered with mycelium and started fruiting condition on day 7.
Very happy with my purchase of Milo. Would recommend to anyone who is interested in making their own grain spawn.
The coco husk is perfect and it's a good price
Thanks for the amazing products and Great Service! Always my go to vendor for grain and substrate
Last week I got the brick to test drive for my microgreens, after using Fox Farm for over 3.5 years. As the rising costs of soil, the weight, the shipping cost and the covering per bag, we needed to find something else. After a couple of days searching I found the bricks from Midwest. I send an email to be sure that I can use it for my greens, signed up for subscription as it saved me 10 bucks and ordered a pack of 4. If it doesn't work well so it be, for 66 bucks, 120 bucks cheaper than the soil, there's not much to loose.
I was anxious, as I never used anything else than soil, your always be careful when changing to a different product.
Used 1 brick with water and was blown away immidiatly as I actually was getting almost 28 gallons of soil from 1 brick, astonishing. Okay now we plant and see if it's working and dam, I'm impressed!!! Greens came up 2 days faster than expected, the soil is the best i've got in years, they water intake is amazing as it holds it much longer than soil. The greens looked great and taste perfectly.
I counted that a pallet of 220 bricks for $1724 incl. shipping, could give me roughly estimated 26 gallon per brick, 5720 gallons which is 764cu.ft, I would need to buy 382 bags of soil to get the same amount of soil comparing to the bricks, I would need to order 8 pallets of soil which ends up incl. shipping at $17236,80 (shipping per pallet at $861). Considering that I get an awesome product that works 10 times better than soil, I also safe $15512,80 that I can invest in my company. I'm sold. The future looks brighter than ever as i stick with the bricks!!
I order everything here first so needless to say… but well deserved…
This company hands down is for mycology and the people!! I bet you bottom dollar I’ll order something or rather from Midwest within the week or 2🤑
WORKS WELL IM IMPRESSED THANK YOU MIDWEST YOIR THE BEST !!!!!☝️
Works great 👍
If contamination is a concern for you, this FFU is definitely worth the investment. With the Bonsai Laser Particulate/Contaminate Meter PM 2.5, I consistently got all 0's up to 5 feet away (only tested up to 5 feet), as long as I stayed within the 23" × 23" area in front of the filter. Outside that zone, particle counts are still very low.
Every thing went well !!! Beautiful mushrooms!!!!
