Pre-Poured Sterilized BLACK MEA Agar Plates (10-Pack)
Freshly Poured Daily · Carbon-Rich · Maximum Contrast for Mycelium Evaluation
360° view: bright white mycelium against deep black MEA for optimal contrast and sector visibility.
Take your culture work to the next level with Myco Labs Black MEA Agar Plates. Specially formulated with activated carbon, these 90mm plates provide exceptional visual contrast—making white or light-colored mycelium stand out clearly against a deep black background.
Poured fresh daily in a clean-room workflow and sealed for protection, Black MEA plates make it easier to observe morphology, detect early contamination, and isolate your strongest genetics with confidence.
What’s Included
- (10) Sterilized BLACK MEA Agar Plates
- 90mm Polystyrene Petri Dishes – durable, lab-grade clarity
- Carbon-infused MEA formula for enhanced visibility
Why Choose Black Agar Plates?
- Maximum Contrast – white mycelium pops against the dark surface
- Improved Sector Identification – easier to see growth edges and isolate clean transfers
- Carbon-Enriched Formula – activated carbon may help reduce bacterial spread
- Machine Poured & Pressure Sterilized for consistency and reliability
- Storage: refrigerate and use within 3–4 weeks for peak performance
What Is Black Agar & Why Use It?
Black agar is a nutrient-rich malt extract medium infused with activated carbon, giving it its dark appearance. It serves three primary purposes in mushroom culture work:
- Contrast: Makes white/light mycelium highly visible.
- Clarity: Helps identify morphology, sectoring, and pigmentation.
- Cleaner Evaluation: Easier detection of subtle contamination or mixed growth.
Simply place a small drop of spore solution, tissue, or liquid culture onto the plate and incubate. Once growth appears, transfer a clean wedge to grain jars, spawn bags, or liquid culture for expansion.
Which Agar Plate Should I Choose?
Each agar type serves a specific purpose in your workflow. Here’s a quick comparison to help you choose:
| Agar Type | Best For | Why Growers Use It | Recommended Stage |
|---|---|---|---|
| Black MEA (This Listing) | High contrast evaluation, isolation, showcase plates | Dark background makes sectors and edges easier to see | Any stage (ideal for detailed evaluation) |
| Regular LME / MEA | Spore germination, first plates, contamination checks | Reliable baseline media for early-stage culture work | Start here → first transfer |
| Rapid Rhizo | 2nd & 3rd transfers, aggressive sector isolation | Encourages strong rhizomorphic, threadlike growth | After clean-up → final transfers |
| Manure-Enriched / Conditioning Agar | Performance testing, conditioning for bulk substrates | Tests genetics on richer, supplemented nutrition | Mid-to-late stage |

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
