I bought the Deluxe Spawn Bag Growing and Casing Kit.
And it more than exceeded my expectations. Everything in the kit was top quality. It came with absolutely everything I need to grow from start to finish. And with the help of the detailed instructions on how to properly sanitize an inoculate the grain bags. I was able to successfully inoculate both bags without contaminating them. They have already Begun to show signs of growth, and it's only been just over a week. I would definitely recommend this kit to anyone wanting to grow for the first time or anyone looking for a complete kit at a great price.
Within 2 weeks of mixing, I had several pins popping up. And 5 days after that, my PE+ was making great progress. Very proud.
My digital hydrometer ceased working, but I’ll reach out to Midwest support for that.
Purchased 2 other brands of all-in-one bags from other vendors and they both ended up getting thrown out after 3 months of almost no colonization or just sitting fully colonized and never producing anything. This was the first bag to actually work for me! I would highly recommend using their 3-pack of quick culture jars first to germinate spores and then inject like 20cc of the culture, this sped my grow up by a month I feel.
We're always happy with everything we get from Midwest. We've had great success with our mushroom cultivation.
Just inoculated a few days ago and already got growth definitely going to get more
Awesome setup I just wish the shelves were a little taller to get dub tubs on easier but all in all great setup
Just started using this setup, and it’s great so far. Everything arrived well-packaged and clearly labeled, and the quality looks solid. The process was straightforward, and the company provided helpful guidance that made getting started easy. Looking forward to seeing how it performs over time, but first impressions are very positive.
Works exactly as advertised. Very well made will last for years. Would recommend
They work well if you know what your doing...good quality.Ive bought 3.
This la was a great purchase!! Made the process clean and easy an it definitely increase my inoculation rate
This is a wonderful product. I do think the zippers need the user to be calm and present or it may develop a habit of snagging. Like camping gear, it is really tricky to get to refold in order to fit in the storage bag, but I was able to get the hang of it with enough calm practice. :)
LOVING THIS ECO MUSHROOM TENT. DEFINITELY A WISE PURCHASE ON MY PART. DEFINITELY WILL BE PURCHASING MORE IN THE NEAR FUTURE, THANK YOU SO MUCH.
Just opened up and used for the first time. So far so good. Happy with the amount and to the eye seems clean. Only time will tell but so far havnt been disappointed from this company so I'm sure this product will serve its purpose.
