Featuring a self-healing injection port and a 0.2 micron breathable patch, it offers contamination resistance and optimal gas exchange. Ready to use out of the box, this grain bag simplifies mushroom cultivation for both beginners and pros seeking reliable, high-quality spawn. ## Description Grains are an awesome choice for growing mushrooms. They take mycelium well and will spread evenly. Depending on conditions such as temperature, humidity, and other factors, mycelium will be able to spread in as little as a week. Our grain bag comes equipped with a self-healing port making injections easy and reliable. Additionally, the 0.2 micron patch allows for better breathing and overall better growth. Starting off right is one of the most important factors for mushroom growing! Our grain bags can be a great start! Review: This product is the first step towards successfully growing mushrooms at home. It is 3 and 1/2 lb of grain-based medium on which the mushrooms and mycelium can grow. It is placed in a sealed mushroom bag, that is one that has a small port for injecting spores into the grain medium. It is still very highly recommended that you sterilize the bag before you use it, and then at least wipe down the port with rubbing alcohol before you inject the spores. Other than that you should have everything you need to begin to colonize the spores. Despite a few important considerations for healthy growth, it is very easy to use this bag and to grow mushrooms. The ingredients are high quality and the bag itself is made of a durable, water resistant bag. Although price gets more reasonable with higher quantities, this one is a good value for the money. The grains themselves are very responsive to growing spores, and the mycelium for my oyster mushrooms grew very quickly and aggressively inside. There are other steps, and there are other things to learn about growing mushrooms, but the first step in a successful first grow would be purchasing this bag with the grains. As long as you keep all those considerations in mind, this bag performs very well. The completely clear, steam proof plastic allows you to carefully watch the mycelium grow. The appearance of white stringy material throughout the bag will indicate that you are ready for the next step. Overall, a great beginner's item for initial mushroom growth! Review: Clean. Well sealed. Ready to use. If you're not 100% clear on what this is or how to use it, you might be confused or disappointed in the condition of the grain. This is a bag of sterilized grain ready to be injected with spore cultures to start mycelium growth prior to blending with substrate before you grow your fruiting bodies. The grain may appear wet, but so long as you don't see any mold or growth inside the bag, it is perfectly fine. The bag should not be opened until it is fully colonized with mycelium. With the primer aside, this bag makes getting a sterile start for your mycelium quite easy with few worries about cross-contamination during the inoculation process. Simply sterilize your needle and the injection port with 90% isopropyl alcohol and you should be fine. The only issues I had with this grain are nominal: First, my bag weighed slightly under 3lbs - 2.87lbs to be exact. This might be within the company's margin of error, but it was significant enough that I thought I should mention it. Second, at over $30 (time of writing) the price is a bit higher than similar packs of pre-sterilized rye grain. Other than that, it is good quality grain that makes a great starter for your mycelium. ## Features - HEALTHY, WELL-HYDRATED & STERILE. The grains have a great balance of hydration making it great for mycelium growth. We sterilize the grain bag to make sure it gets to you in the best condition possible. - FASTEST MYCELIUM COLONIZATION. Our grains have been shown through both tests and satisfied customers to produce great mycelium growth. Grains are a great medium for colonizing, and we highly suggest trying it out! - SELF-HEALING INJECTION PORT & 0.2 MICRON PATCH. Self-healing injection ports are important because they give you more confidence in your growth. They are more reliable compared to bags without ports. Each bag has a premium quality 0.2 micron patch that will allow your mycelium spawn to breathe and grow better. - EASY TO USE AND MINIMAL PREP WORK. The grain bags are extremely simple to use and require very little to start. Simply use a syringe to inject liquid mushroom culture into the self-healing injection port. Place in a dark location preferably 70°F- 80°F. Soon your grains will develop mycelium and spread completely throughout the bag. Then, your spawn will be ready to use! - PROFESSIONALLY PREPARED & HIGH QUALITY. We prepare our product so you are guaranteed the highest quality when using your grains. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BFG84CZV | | Best Sellers Rank | #226,889 in Health ( See Top 100 in Health ) #1,894 in Bin Liners | | Brand | ES EVVIVA SCIENCES | | Capacity | 3 Pounds | | Color | Light Brown | | Customer Reviews | 3.8 3.8 out of 5 stars (36) | | Date First Available | 23 September 2022 | | Item Weight | 1.36 Kilograms | | Material | Plastic | | Product Dimensions | 12.7 x 12.7 x 12.7 cm; 1.36 kg | | Special Features | Self Watering | ## Product Details - **Colour:** Light Brown - **Material:** Plastic - **Shape:** Rectangular - **Special features:** Self Watering - **Style:** Modern ## Images ![ES EVVIVA SCIENCES Grain Bag 3 LBS for Mushroom Growing – Easy to Use Grains – Self-Healing Injection Port – 0.2 Micron Patch – Ready to Use Immediately - Image 1](https://m.media-amazon.com/images/I/91s-4KY1j3L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by S***E on 12 October 2023* This product is the first step towards successfully growing mushrooms at home.
