Rapid Rhizo Pre-Poured Sterilized Agar Plates (5-Pack)
Freshly poured. Lab sterile. Rhizomorphic results.
360° view: see the style of growth, fill level, and finish of each pre-poured plate.
Take your mycology work to the next level with our Rapid Rhizo Agar Plates—expertly formulated to promote fast, aggressive rhizomorphic mycelium growth. Whether you’re cleaning up samples, isolating top genetics, or showcasing final transfers, these sterilized malt extract agar plates make clean culture work easier and more repeatable.
Unlike agar plates that sit on shelves for weeks, ours are made fresh daily in a controlled clean-room workflow, machine poured for precision, and sealed in polyolefin packaging to help lock in freshness. It’s the highest standard in pre-poured agar—no shortcuts.
What’s Included
- (5) 90mm Rapid Rhizo Agar Plates – pre-poured and sealed
- Custom nutrient + yeast blend designed to encourage rhizomorphic growth
- Clean-room poured with consistency-focused quality control
- Sealed fresh in polyolefin packaging to help preserve moisture
- Storage: refrigerate and use within 3–4 weeks for best results
Why Rhizomorphic Mycelium Matters
Not all mycelium is created equal. While tomentose growth appears fluffy and matted, rhizomorphic mycelium grows in strong, threadlike strands that spread rapidly and colonize efficiently. Rapid Rhizo plates are designed to encourage this prized growth structure, making it easier to:
- Select strong sectors for faster colonization
- Isolate clean genetics through transfers
- Create showcase plates for final “keeper” cultures
Lab Precision, Every Time
All our agar is machine-prepped and machine-filled for unmatched consistency. Each batch is:
- Sterilized at 18 PSI for 30 minutes
- Dispensed with a precise 25ml fill per plate
- Cooled and capped under UV-C light
- Labeled and sealed immediately for freshness
This system minimizes human error and helps ensure every plate arrives clean, consistent, and ready for reliable growth.
Which Agar Plate Should I Choose?
Different agar recipes shine at different stages—spore germination, contamination checks, clean transfers, and final display plates. Use this guide to pick the right plate for your goal.
| Agar Type | Best For | Why Growers Use It | Recommended Stage |
|---|---|---|---|
| Rapid Rhizo (This Listing) | 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 |
| Regular LME / MEA | Spore germination, first plates, contamination checks | A reliable baseline media that makes early growth and contaminants easier to evaluate | Start here → first transfer |
| 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) |

Tip: Many growers start spores on LME/MEA, clean up on early transfers, then finish on Rapid Rhizo (or use Black MEA when contrast matters).
What Is Agar and How Do I Use It?
Agar is a jelly-like medium used to grow and isolate mycelium in sterile conditions. Add a tiny amount of spore solution, tissue, or liquid culture to the plate and incubate. In a few days, you’ll see mycelium growth—then you can transfer clean sectors into grain jars, spawn bags, or liquid culture.
Using agar lets you:
- Isolate strong mycelium
- Detect and avoid contamination
- Work with clean, vigorous cultures
- Improve reliability, speed, and overall results

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
