I started this project back in July and started seeing promising pins around the end of August. I’m very new to the whole procedure, but super content with the product outcome. Still cropping caps 4.5 weeks after the first harvest. Thanks for all the educational support, it’s well organized on the “learn” dropdown.
I can't pass up a new way to get more mushies in my diet. I didnt really have any expectations on this as I am not a fan of Ryze and some other instant mushroom coffees but this really blew me away! I brewed some this morning and the flavor of this specific roast is very very good. I literally cannot taste a hint of the mushrooms! From my guess looking at the beans the mushrooms are freeze dried and super fine. Now I just need K-Cups and larger bags! I will be adding this to my future orders!
Thank you for selling me the most awesome mushroom growing Kit! Easy to assemble- awesome setvup!
Got the bags last week and injected them. Already seeing growth. Thanks.
giving a five because Midwestgrowkits.com is so good to me, but these were misdelivered in the mail. Luckily the neighbors brought the items back, but had a few cold nights. Im hoping there all good, starting new projects before winter is here. All year Midwestgrowkits.com made my needs were met. Can't wait till next year and spring heat returns. Thanks to everyone there, recommend 👍 💯
These are really cool! Long term storage of your favorite genetics without having to keep doing dish transfers. Midwest Grow Kits just has the best quality of everything!
Perfect agar! Great job on agar quality, plate seal, and overall packaging. Many other vendors don’t seal and package well and the agar can start to lose volume and arrive in bad shape. These are my new favorite.
Great customer service, all products are sterilized ,I've been having great results with no contamination
Love the products.. so far everything has panned out perfectly. Keep up the great work
I love how well packaged your products are.
I'm always guaranteed a vibe in my fruits.🍄🍄
Quality product. I hope to order more as my business grows.
This is exactly what I was looking for. Good structure… a winner! And thank you for the extra freebies my last order.
Grain bags are great I wasn't happy with the agar plates because they weren't wrapped individually and you didn't send any para film I feel like you guys should replace the five agar plates that I got when I undid the main rapper the lids got Jarred around and they ended up contaminated all of them but one the one I called a mushroom with so out of the five I only was able to use one of them but other than that your business has been great I love every product of everybody I bought a grow kit from you guys a few years back but overall very happy with Midwest grow kits
I got the 45 dollar all in one bag with monotub and their tubs are the best, their all in one bags are the best and cheapest, amd their substrate is the best with more mushroom growing ingredients than the competition..
I am going to buy the jars next so I can reuse for liquid culture,bag of substrate and 2 monotubs bc their tubs work wonders compare to modified bins. Simply the best in the business.
