Our Mission

Here at themushieunderground our business model has always been to provide our customers with high quality products at affordable prices! We have combined our years of knowledge and experience to build a community full of helpful information, tips, and support to help you along the way. We stand behind our products and have some of the highest customer satisfaction levels in our field, as well as a 95% customer return rate.


We understand how overwhelming it can be for those first starting out, which is why beginners love shopping with us as much as mycology experts do! With our out of the box thinking we have created innovative, new equipment, techniques and approaches (C-tek) to help those at any skill level. For beginners, we have a simple straightforward method that has removed all the unnecessary and costly components, making it much easier and cost efficient. For those who have experience and want a challenge, we have more complex methods and equipment to try. Our mushroom spore library is one of the largest in the US and is made available to our customers. It has taken years to build and contains some of the rarest, hard to find genetics, as well as a few of TMU’s very own own creations.

Privacy policy

If you do not receive your purchase and have allowed 10 business days to pass, please reach out to us by email at We also ask that you please include your name, address, purchased items and total cost of purchase, list any items that are missing or broken, if broken please supply clear pictures of the broken items that show the items damage. Emails are typically returned within 24-48 hours as we strive to meet high customer satisfaction. We will do our best to track your package and update you as quickly as possible. We do not accept returns on perishable items, those are final sale. If you are not satisfied with equipment purchased from us you may return it as long as it is still unused up to 30 days after purchase, unless a listed item specifically states it is a final sale for which no refunds will be granted. We do not pay for return labels; you are responsible for the return shipping costs and will not be reimbursed for it. You will however be given a refund for the amount paid for the equipment once we have received it, and verified it is still in working order. TMU's core foundation is built on creating a community and providing education for those who are searching for it. If there are any issues please reach out to us and we will do our best to rectify the situation! 

Thank you

If you think this Man or the TMU family isn’t real or something. I’ll be real about it. They’re going to sell you 💯% best research supplies for mycology that you can buy…. The genetics are all isolated and atleast 10th gen’z or more… So I advise you and everybody else too be part of the TMU family and buying all your mycology needs from here… Best service ever cuz you can text or email them and they’ll hit you right back answering any questions you could ask about mycology. They’re awesome and I think they are going to change the world a little bit. Thanks guy’s. Mush love,

It would be foolish to go elsewhere I placed an order with a competitor before finding TMU and it didn't get delivered for a month and a half.  The price, word of delivery, quality and quantity of TMU cannot be beat.  This is one of the best companies I've ever done business with hands down. Two thumbs up.


OMG! I won 2nd place in the drawing.  All I can say is WOW!!!!! Just got my package in the mail. I'm in total AWE!  You've most definitely won my heart for a lifetime.  So thankful. This prize is just amazing.  So many new strains.  Love the entire package. I'll be wearing the t-shirt all over town. A new favorite! 
Thank you so very much. I'm truly grateful for your generosity and love for mother nature's gifts. 
You are by FAR the very BEST there is. 
If you could only see the joy you've given me.

Been a customer for almost a year and I have got to truly say that Carl the owner operator is one of the coolest people I’ve had the pleasure of dealing with. I’ve tried other sellers and must say the he is the real deal. And will always look out for his customers. He is one of the last of a kind breed of people that do care. I suggest that if you’re shopping around then look no further…… deals deals n more deals of quality spores n a one stop shop for all your needs. Quit messin with unreliable sellers n mark this site as a fav. And this is truly a customer 💯 % n will never buy anywhere else. Kindest person I’ve met in a really long time. Meet all your orders here noplace else. You have my word on it, you WILL BE HAPPY with all it purchases. Mush love
