I’ll see how this goes. - January 18 Update: So, as expected the "break and shake" took a bit of rigor, but I was able to distribute the agar slices and the colonized grains throughout the jar. And both jars ultimately colonized fully and nicely. At this point both jars have been transferred to substrate, and there is still no contamination (so far...no whammies!) in either batch...and the unused third jar still appears clean. So despite my concerns below...all's well that ends well. ...and I recently ordered another set of jars. I just received them, but they also appear free of contamination. Bumping the star rating to a well-deserved fiver. Recommend. Dec 18 (Orig): I ordered these, basically to use while I work to get my own jar/bag sterilization equipment and technique operational. And not a bad price for (reusable) quart-size sterile jars with grain. (A 4 quart option would have been nice though, and maybe some pint-size options, but minor gripe). I grew some mycelium from spore on agar (or rather, it grew). When I went to transfer the agar slices to these jars (two of three jars used so far, half plate to each), I realized that Myco Labs filled the jars a little too full, causing two issues. 1. There was dried grain on the outside “shoulders and neck” of the jar, and opening the lids was a little “gritty”. These jars sat at for a month after delivery, without apparent contamination, covered by the “autoclave foil” and bubble wrap…so that’s promising. I tightened the lids after transfer well, but if there is grain on the outside/neck of the jar, with a gritty twist, I question the lid seal. Time will tell. 2. There is little to no room for a “break and shake”. The listing pictures show a fill to a ~1/2 inch below the jar “shoulders”, and even then I’d fill a little lower. I still have to remove the cover and foil on the third jar, but two of them were almost filled to the lid. It even took some rigor to get the agar slices “submerged” in the grain, and I can’t be sure of that on one of them. I suppose I could have dumped some grain out, but at the time of transfer, I did not want the jars open for a second longer than necessary....let alone fiddling with dumping. Again, I’ll see how this plays out, but even with a syringe inoculation, the “break and shake” would be tight. I can’t rationalize grain on the outside jar necks…but I somewhat understand (assumingly saturated) grain expanding (a little) during sterilization…but Myco Labs need to work that out to a full but "headspaced" level. I'll add pictures later, but I also see overfilled jars in pictures from other reviewers. Review: Perfectly Sterile - All 3 was perfectly sterile. I had no contamination, and 2/3 already in 3 flushes. Last one was sent to S2B (since it was a MSS it took longer). It inoculated fast. 2 jars were big enough for my inflatable tub. Easy to work with. Very sturdy, recommend breaking it up with a bottom of a shoe when needed. ## Features - 3-PACK (32 ounce) Jars of organic rye berries mixed with small grains for faster colonization times. - Each jar comes with a premium 0.22 micron filter disk and a self-healing injection port for easy and error-free inoculation - Pressure sterilized at 15 psi for 120 minutes, ensuring the jars are free of contaminants upon arrival. - Speeds up the growth of your bulk/monotub setup, making it easier and quicker to achieve successful results ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D2PG7RN2 | | Best Sellers Rank | #36,911 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #103 in Plant Germination Kits | | Customer Reviews | 4.2 4.2 out of 5 stars (253) | | Item model number | QPC3 | | Manufacturer | Myco Labs | | Product Dimensions | 12 x 5 x 7 inches | ## Images ![Myco Labs Premium Quick Colonizing 32oz 5-Grain Mushroom Spawn Jars (3-Pack) - Image 1](https://m.media-amazon.com/images/I/61BNi3Rc34L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ No contam, but a little overfilled.

I had no contamination, and 2/3 already in 3 flushes. Last one was sent to S2B (since it was a MSS it took longer). It inoculated fast. 2 jars were big enough for my inflatable tub. Easy to work with. Very sturdy, recommend breaking it up with a bottom of a shoe when needed. ### ⭐⭐⭐⭐⭐ Lazy Tec perfect for inject and forget *by T***T on January 16, 2026* Works as advertised colonizes relatively quickly, depending on how aggressive your culture is. I haven’t had any contamination issues with them and have used several times. It’s worth the $10 a jar instead of me having to sterilize plus comes in jar just inject and wait to colonize ## Frequently Bought Together - Myco Labs Premium Quick Colonizing 32oz 5-Grain Mushroom Spawn Jars (3-Pack) - Myco Labs Premium Bulk Mushroom Substrate Mix | Fully Pastuerized | Maximum Yield | for Dung & Grain Loving Mushrooms (5 LBS) - Premium Liquid Culture Kit Easy Spore Germinating & Mushroom Cloning System --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.kw/products/624999309-myco-labs-premium-quick-colonizing-32oz-5-grain-mushroom-spawn](https://www.desertcart.com.kw/products/624999309-myco-labs-premium-quick-colonizing-32oz-5-grain-mushroom-spawn) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-04-22*
