24oz Premium Super Quick Colonizing 5-Grain Spawn Jar
Lightning-Fast Colonization • Tapered Glass Design • Sterile Grain Spawn
The Midwest Grow Kits 24oz Super Quick Colonizing 5-Grain Spawn Jar is engineered for growers who want faster colonization and easier spawn handling. This sterile grain jar uses a high-performance 5-grain blend combined with a tapered glass jar design that allows the fully colonized grain mass to slide out more easily when it’s time to spawn to bulk substrate.
Compared to traditional 32oz jars, the smaller 24oz size often allows for faster colonization times, while the specialized grain blend creates more inoculation points for aggressive mycelium growth.
Why growers love these jars: The smaller jar size helps speed up colonization, while the tapered glass design makes removing the colonized spawn easier when transferring to bulk substrate, monotubs, or grow bags.
Why Choose the 24oz Super Quick Colonizing Jar?
- Faster Than Larger Grain Jars – Smaller jar size supports quicker colonization cycles.
- Tapered Glass Jar Design – Allows the colonized grain to slide out more easily once fully grown.
- Rapid Colonization Grain Blend – High ratio of smaller grains increases inoculation points.
- Clean & Easy Inoculation – Self-healing injection port works with spores or liquid culture.
- Reliable Gas Exchange – Premium 0.22 micron filter disk maintains airflow while protecting sterility.
- Great for Bulk Growing – Ideal for monotubs, trays, casing mix, and bulk substrate expansion.

Built for Speed and Easy Spawn Transfer
The 24oz Super Quick Colonizing 5-Grain Spawn Jar was developed for growers who want both faster colonization and easier spawn handling. The smaller jar size allows quicker growth while the tapered design helps the finished grain spawn slide out more cleanly when it’s time to mix with bulk substrate.
This makes the jar especially useful for growers using monotub systems, bulk substrate grows, and casing mix where quick colonization and easy jar handling can help improve workflow and consistency.
Fast Colonizing Grain Spawn for Mushroom Cultivation
The Midwest Grow Kits 24oz Super Quick Colonizing 5-Grain Jar provides a sterile, ready-to-use spawn option designed for fast colonization and easy transfer into bulk substrate. If you want a grain jar that moves quickly and simplifies spawn transfer, this is one of the most efficient options available.
Let customers speak for us
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!!!!
Wet and taking off like a jet 🥷
Thank you MWG 🙌
This kit contains everything you need to start growing your own mushrooms (except the genetics of course).
I inoculated the grain with Gorilla Wizard LC on 3/1 then did a break n’ shake on 3/12.
11 days later on 3/23 I transferred the grain spawn to bulk substrate in the monotub (I added a casing layer on top).
It’s been about a week now and it’s showing nice recolonization :)
I’m very pleased with this kit. The 44q container is fantastic! It has a tall lid so your mushrooms are able to grow and stretch :) I’ve tried other monotubs (like the inflatable one - the concept was great the practicality of it wasn’t quite up to par),
So far everything about this company has been great, I haven’t had any contamination or anything. I will update in a couple weeks the outcome of my Gorilla Wizard grow :)
SIMPLY THE BEST,BETTERMENT THAN ALL THE REST THANK YOU MIDWEST YOU ROCK !!!!!!!!!!😎😎😎😎😎😎😎
I love this company and I’ve had 100% success rate with their products!!!!
These silicone lid covers are a game changer. When I prep grains, water always finds a way under the foil and onto my lids no matter how tight I get the foil. These lids go on quickly and keep my jar lids nice and dry! This is big for anyone using paper filter patches for gas exchange. Thank you Midwest for having exactly what I needed!
I know these are probably designed for all-in-one setups, but recently I've come to find spawning 2 bulk in these types of bags incredibly effective. Instead of mixing a grain bag (2-2.26 lbs) into 5 lbs of substrate in a pan, I like to make two nice big round babies with the same amount. For measure, these bags could easily hold 10 lbs of materials, and the real reason I got them was due to the concern that the tops of the smaller ones would not so easily receive pouring from other large bags. Plus, the sale price and potential for extra filtered air flow sold me solid. That said, the downfall of such a large bag was sealing them was much more difficult. I should have ordered MGK's expert bag-sealing device instead of the inoperable hank of jank I wound up having to return. Nevertheless, tape sufficed.
I almost bought the regular Complete 44Q Kit and saw this and decided to splurge. All I can say is it was well worth it. Everything colonized and re-colonized much faster. I used to use a space heater in my grow room and that added a chunk of cash to my electric bill. This setup is awesome. I am only 9 days after breaking up my spawn bag and mixing with substrate and I am seeing pins everywhere! My only suggestion is to add 3 filter disks on the opposite side of the air pump. This helped me dial it in in my room which is already kinda humid here in Georgia.
No bacteria no broken jars solid 10/10 perfect condition. Will be Buying more!❤️
I love y'all's mono tubs they work great I would like to have a top for one of them it's about 6 in taller just so I can get this one strand of mushroom that grows a foot tall but I'm going to work out something with that different with the whole group that I think.
I've already recommended your products to friends and family.
Everything I ordered from y'all has come quickly and package good.
