## Customer Reviews

### ⭐⭐⭐⭐⭐ easy to use
*by K***  on February 28, 2024*

simple mixing and coincidentally my harvest was great for first time using the product

### ⭐ Not nearly enough dirt in the package
*by P***K on November 13, 2023*

The first 2 times I bought Uncle John's mycodirt, it came with 3 packages that needed to be mixed in the bucket. It was simple enough and it worked out fine.I ordered again and the "updated product came premixed in 2 bags. They weighed 2.5 lbs in total. It seemed light for a 10 lb mix, bur I followed the directions to the letter. I ended up with 2" of standing water on top of the saturated dirt in the bucket. There is simply no way that 2.5 lbs of substrate can hold 14 cups of water! I emailed the company and have not heard a word back.I reordered the product and I got the same 2.5 lbs of premixed substrate. I boiled 14 cups of water as directed, and this time, I added it slowly, stirring it in with a sterile spoon instead of pouring it all in at once. There were 6 cups of water left over!Either the last 2 boxes I bought were short a bag of dirt or someone at Uncle John's neglected to update the directions in the YouTube video. Lest you think that I'm a dolt and can't follow directions, I was a full-time environmental scientist for more than 35 years. 14 CUPS IS WAY TOO MUCH WATER!In either case, it would have been nice if someone from the company had returned an email after I reached out .I won't be buying Uncle John's premixed substrate again

### ⭐⭐⭐⭐⭐ Great stuff. Instructions are very clear and this was my first time growing
*by M***E on July 28, 2023*

I selected this product after looking at a few others that were similar for mushroom substrate. There's quite a few that are pre-pasteurized, and despite this being my first time jumping into mycology, I decided to try this mix. It's a great product. The instructions are clear, and they even throw in a few stickers as well. Make sure you have a 5 gallon bucket that's clean and wiped down before you start.
