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.

I was getting alot of contam with northspore boomr bag strait garbage company. Contamination central at northspore almost everything contams. I tried a couple other companies then tried this blackcow. Its black gold Texas T the biggest dummy in the world will get massive flushes with this. The grain bags are awesome too and sterilized right. I went 14/14 on the grain bags. Midwest know what they are doing and even the packaging is next lvl everything double bagged. I only buy from midwest it's worth every cent
It's been several days since the Ecosphere arrived and I set it up, and I'm still amazed at all I got for the price: heater, fan, humidifier, two plug-in timers, two foil trays, and, of course, the five-tier tent with shelves and the plastic cover. Oh, and the LED light strip and the round air filters. It's everything I need right now, and I've started the growing process. It's a crazy good deal for the price. I'm new to mushroom growing, and I'm thrilled that I bought this setup as a start. Just plain wonderful.
Fast and easy colonization! These grain jars showed growth after just 10 days. My previous efforts with the all-in-one bags are taking MUCH longer but also working. Thank you Midwest Grow Kits 🙏
I love the people and the products. The people at MWGK clearly care about the integrity of the community they serve.
The monotub works amazing only had it a couple of weeks and about to have second harvest I used AIO grow bag for first flush and move to tub for second and its great not having to watch 24/7. Thanks Midwest
Four days after mixing grain, Select substrate, and the Midwest horse manure booster - the results speak for themselves.
It has everything you need for a fast, large flush success with fewer moving parts than a standard monotub. It is a surprisingly versatile option for more advanced students. Pic is 5 grain jar at 8 days. GT LM This is where I shop, now.
Rich, perfectly field-wet, sterile and it is perfect for those many varieties that won’t thrive quite as well in Bulk Substrate and Casing Mix, which I’ve seen as best for psilocybes/cyanescens. I’m using it for the first time with Lions Mane and King Trumpets. So far so good, 7 days and primordial and pins are starting to flourish. It drains better and is lighter than MGK’s Bulk Casing and Substrate. Great product.
Love the heater and how even and exact it heats. I set mine to 76 degrees and my room fluctuates from 64-75 and it holds solid at 75 degrees. I used a probe thermometer to double check the substrate level temp and its exactly 1 degree less than the heater setting. Another tip, I only needed to use the round monotub thermometer to check my humidity levels every so often. I would leave a filter disk on that hole instead of the thermometer. The only time it came in handy was after my first flush when humidity started to drop. I was able to use that gauge and check whether I needed to mist. Overall great kit and worth the money!
Ive bought mutiple jars before i came up with my own recipe, every jar produced healthy cultures, even if ones damaged in shipping they replace immediately, highly recommend
Very small chance that you get a contaminate you already had it and you’re either culture spores etc. their stuff is 100% sterile every time 100% of the time everything is viable never had a problem been shopping with them for sometime
It’s very good product and I highly recommend it to everyone.👏👏👏
I love my magnetic stir plate it works great for Liquid culture jars.
My bag had a slow start, but excellent finish. Oak Ridge.
Great product for my cannabis best deal around arrived fast thank you Midwest grow kits definitely will be purchasing again
