Mushroom Grow Bags & Kits FAQs

What is the difference between our mushroom grow bags and kits?

The main difference between the two is the overall size. Our All-In-One Mushroom Grow Bag products contain everything you need to get a bountiful harvest and are perfect even for those with no experience. Our kits, on the other hand, come with four bags and are perfectly suited for experienced mycologists who are looking to grow multiple strains at the same time. 

Do you ship in discreet packaging?

Yes, all our products will be shipped in plain brown boxes, so you can safely and discreetly begin your mushroom cultivation journey.

Which should I choose - mushroom grow bags or Uncle Ben’s Tek?

There are lots of pros and cons to using Uncle Ben's Tek, however, most people find that the cons are not worth it. It usually involves a much more complex process which leads to a higher risk of contamination and longer cultivation time - and plenty of things that could go wrong. Not only that, but when you inject spores or liquid culture into your bag, there's no good way to heal the little hole and so there's even more risk of contamination.

Our mushroom grow bags are the ideal choice for those who want a smooth growing process with minimal chance of failure. The bags are perfectly sealed and sterilized specifically to avoid the issues people have with Uncle Ben's Tek. Not only that, but they come with a self-healing injection port to fully reduce any contamination when injecting into the bag.

How long does it take to grow mushrooms using Mushroom Spawn Store kits?

The growth time for homegrown mushrooms usually ranges between 5-8 weeks from set-up. This time can vary widely though, depending on the specific conditions of your growing environment and the specific variety of mushroom.

Who are mushroom grow bags suited for?

Our mushroom grow bags and kits are suited for first-time growers as well as veteran mycology enthusiasts. They are a great way to get started in the fascinating world of mushrooms, and reap the physical and mental health benefits in no time.
