Rapid Rhizo Pre-Poured Sterilized Agar Plates (10-Pack)
Now in a 10-Pack · Freshly Poured Daily · Made for Aggressive Rhizomorphic Growth
360° view: see the rhizomorphic style growth, fill level, and finish of each pre-poured plate.
Level up your mycology work with our Rapid Rhizo Agar Plates in a convenient 10-pack. These pre-poured plates use a custom nutrient + yeast blend that encourages fast, aggressive rhizomorphic mycelium—making it easier to isolate your strongest genetics and capture clean, photogenic transfers.
Unlike agar that sits on shelves for weeks, our plates are poured fresh and sealed in protective packaging to help preserve moisture and performance. Whether you’re cleaning cultures, transferring isolates, or showcasing final sectors, Rapid Rhizo provides the aggressive edge experienced cultivators look for.
What’s Included
- 10 Rapid Rhizo Agar Plates – 90mm polystyrene Petri dishes
- Pre-poured & ready-to-use – no mixing, sterilizing, or pouring
- Fresh production – made for consistent performance and strong growth
Key Features
- Promotes Rhizomorphic Growth – excellent for 2nd/3rd transfers and “showcase” plates
- Pressure Sterilized & Poured under clean workflow conditions
- Consistent fill – machine-dispensed 25ml per plate
- Storage – refrigerate and use within 3–4 weeks for best results
Machine-Poured Precision You Can Trust
All plates are produced in a controlled workflow using automated prep + dispensing systems for repeatable results. Each batch is:
- Blended and sterilized at 18 PSI for 30 minutes
- Cooled and dispensed with exact 25ml pours
- UV-C treated, capped, and labeled for consistency
Which Agar Plate Should I Choose?
Different agar recipes are useful at different stages—spore germination, contamination checks, clean transfers, and “final” display plates. Here’s a quick guide to match the plate to 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” nutrition profile that makes early growth and contamination easier to evaluate | Start here (spores/tissue) → 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) |

Manure-Enriched / Conditioning Agar
Tip: Many growers start spores on LME/MEA, clean up on early transfers, then finish on Rapid Rhizo (or use Black MEA when visibility matters).
What Is Agar and How Do I Use These Plates?
Agar is the foundation of clean culture work. Place a tiny amount of spore solution, tissue, or culture onto the plate and incubate. Within days, mycelium spreads across the surface—letting you isolate clean growth away from contamination.
- Spore to agar: start genetics and identify contaminants early
- Transfers: isolate clean sectors and refine growth
- Final plates: preserve your best genetics for grain jars, spawn bags, or liquid culture

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
