Let customers speak for us
I like everything about this setup. The time of ownership is too short to discuss fruiting mushrooms but the incubating mycelium seem to be doing well for now under the recommended temps. The one thing that would make this setup better would be the inclusion of an electronic controlled hygrometer to run the vaporizer.
Unit was just giving 0 on everything except air Temp and Humidity. Called customer and they are taking care of. Happy with customer service.
I think these are the best co2 boost bags on the market especially the price. More bang for your buck. My buds have been alot bigger, and alot more dense, stacking like a roll of silver coins! And alot more of a yield too! I will always use these co2 bags in every grow, they are definitely worth it! Unless you like fox tailed loose and airy buds!
These pellets work very well. Especially if you do no-low heat drying. Also helped,e save some that got soggy. I put a pinch of the pellets in the jar, and they dried up overnight.
These work, 2-3 per oz of dried mushrooms. Keeping them cracker dry.
Thank you for the fast shipping and awesome packaging! Love the insulated bags and ice packs! I am seeing some extremely aggressive growth in my sawdust bags after only 3 days! I have found my new spawn vendor! Please keep everything in stock! So hard to find good grain spawn these days without waiting a month.
I injected 2cc's into this 6 days ago, noticed first signs on day 4.
The unit came packed very well and easily assembled. My order did have an issue in that I was given a deficiency in the number of long screws I needed to complete the build. A quick email to customer service had my screws i the mail ASAP. Perfectly executed and best case scenario for an issue like this. SO far the unit operates as advertised and is a major upgrade to my home mycology process. I would recommend this product to anyone who wants a nice laminar flowhood but is not so inclined to design and build it from scratch. Components are well constructed and of good quality materials.
Super accurate. I use for each strand of research I do- a qc must!!!!
I inoculated on 3-18-26...fast forward to 6-1-26...I received my 28 quart monotub right on time..I took the cake out of the all in one grow bag best thing I could've done...I got to see how hyphae knots form them I got to see the primordia form..then I consulted with Midwest grow they said in two weeks I will have pins.. they were spot on..I'm extremely satisfied with this company best in the business...and now fruits...ty Midwest grow...
I injected about 3ccs of a liquid culture I had into this jar and within a day or two I could already see it expanding. It’s convenient that it comes with a stir bar already in the jar, make it easy to swirl around a couple times a day. I’m currently awaiting my agar results to determine if it’s 100% clean, but I don’t see any contamination. Highly recommend if you want to expand your LC and make it go further.
Have all the tools I need. Thanks, Midwest. I'm new to the world of fungi, but your help is appreciated.
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.
