Q: Do you sell spores?
We do not sell spores. We specialize in the growing mediums. Spore companies specialize in producing spores. Each kit requires a spore syringe to use. Every jar requires a little less than 1cc of spore solution each. Each Spawn Bag requires 3-5 cc's of spore solution each. Spore syringes are typically sold in 10cc syringes. For example, 12 substrate jars would only require one spore syringe to use.

There are hundreds of websites specializing in spores. Some are great, some are good and some are bad. We have received countless reports and reviews from our customers over the years and will be more than happy to share that with you. Please contact us if you would like a full list of our recommended sites and sites to avoid! Many "cheap" or "bargain" spore sites buy their supply from overseas vendors from Malaysia and are usually very poor quality. Our top 3 list changes every few months based on customer feedback!

Q: How much spores do I need for each kit?
Almost all spore syringes are sold in 10cc units. Typically each jar requires around 0.75-1.5 cc’s of spore solution. Each Spawn Bag requires 3-5 CC’s per bag. Spores last 6-9 months or longer stored at room temperature. Many people like to grow different strains in the same kit. This is perfectly fine as long as they require the same growing temperatures. Do not mix strains in the same jar or spawn bag.

Quick reference on how many spore syringes you need:
Simple Kit or 6 Jars: 1 Spore Syringe (with leftovers)
Ultimate Kit or 12 Jars: 1 Spore Syringe
Mega Kit or 18 Jars: 2 Spore syringes
5grain spawn Bag (2): 1 spore syringe
24 or 32oz 5grain Jars (3): 1 Spore syringe

Q: What is the over-view of the process? How long does it take?
All of our growing mediums are carefully prepared and pressure sterilized. We do the hard part and all you need to do is add spores! For most kits, simply set up your kit as an incubator for the first step, Inject your favorite spores into each jar, watch them quickly colonize, remove from the jars, adjust the heat to fruiting temperature and place each jar into the grow chamber and watch the mushrooms grow. Almost everything in the kit can be re-used so you can keep growing. You'll typically have your first harvest in 4 weeks! They will grow for an additional 4-6 weeks! 3-4 times!
Q: Will spores intended for Dung loving mushrooms work on grain based products?
Yes, grain and dung are interchangeable. When you see dung loving, you will always want to start with a grain based jar or spawn bag.
Q: Why should you choose Midwest Grow Kits for your mushroom growing needs?
There are many reasons you should consider Midwest Grow Kits for your mycology needs. Midwest Grow Kits has been selling mushroom growing supplies online for over 14 years.

Q: What are the shelf life of Jars and Spawn Bags?
All Jars and Spawn Bags are prepared fresh and meant to be used within 4-6 weeks of receiving the items. You can extend the shelf life by a few weeks by placing items in the fridge or storing in a cool dark place.
Q: What is Bulk Growing or Bulk casing?
Growing in Bulk is generally referred to as the process of using your fully colonized spawn bags or even jars to mix with a layer of mushroom friendly soil (Coir, vermiculite, Peat moss, etc..) Mushroom casing serves many purposes in bulk growing. It provides a medium to grow into, stimulates the formation of mushrooms, provides moisture and protects the substrate from drying out from the air. This advanced growing method is now perfect for beginners. Our Premium Select Casing Mix & Bulk kits make growing in bulk much easier!
Q: Why doesn't this promo code work?
We run different discounts and offers throughout the year. Most of our discounts are for returning customers only. These codes eventually are shared by other websites and coupon sites so we have to change the codes. If you have a valid promo code and it doesn't work, please contact us for the updated code. We cannot apply a coupon code to an order already placed.
Q: How long does it take to grow?
With most of our kits it takes approximately 3-4 weeks for the mushrooms to incubate or colonize the jar. You will typically see your first batch of mushrooms in the 4th or 5th week. They will continue to grow for an additional 4-5 weeks with one "flush" or batch per week on average.
Q: What if I have growing questions along the way?
We offer telephone support, email support and after hours live chat. Many of our team have over 20 years of mushroom growing experience to share with you and help you with any questions or concerns you may have! Unlike other sites our customer service team has actual mushroom growing experience and can help you right away. Please call us with any growing questions you may have! (800) 921-4717
Q: What are the differences between growing in Jars and Spawn Bags?
Growing in jars has always been the easiest way to grow mushrooms. Recently, growing in spawn bags has become just as popular. We usually recommend starting your growing experience with jars because they colonize faster and produce mushrooms quicker. Spawn Bags take longer to colonize, but can produce larger flushes or growth cycles. Spawn bags can be grown with jars in any kit and are the preferred way for growing in bulk. This more advanced method of growing allows you to break up your fully colonized spawn bag and mix it with a variety of different soil type materials to expand your grow. We now offer pre-mixed casing and Bulk Kits that make it easier than ever! If you are a first time grower and want to grow spawn bags we recommend a mix of jars and spawn bags. You can incubate your spawn bags right next to your jars and since jars will be ready first this will allow you time to practice while your spawn bags finish colonizing.
Q: Where can I access the video grow guide or the kit setup directions
When you place an order, you will receive an email order confirmation and a second email containing the link to our Video mushroom growing guide.
