Good product, bit slow on delivery

I ordered a MushBag All-In-One Mushroom Grow Kit. The kit itself was well-packaged and had clear instructions. Everything I needed was included. The only setback was shipping; it took 5 days to reach Denver, which felt a little long. Otherwise, I'm happy with the purchase.

Awesome kit, definitely ordering again!

Got the Lion's Mane Grow Kit and it's been fantastic! The instructions were super easy to follow and the mushrooms are growing so fast. I was a bit worried about shipping but it got here quicker than expected and everything was packed securely. I'm already planning my next order, probably another kit or some agar plates to try. Martian Mushrooms did a great job!

Smooth order, great results

My recent purchase from Martian Mushrooms was for a Sterilised CVG Mushroom Substrate Bag and a Liquid Culture Syringe. Ordering online was straightforward and the website was easy to navigate. I received a tracking number quickly. Shipping was discreet and arrived in about four days to my address. The substrate bag was perfectly sterilised, no contamination issues, and the liquid culture looks viable under the microscope. I even had a question about storage and their customer service responded within a day. Really impressed with the quality and support.

Hey has anyone used the Martian Mushrooms kits before? Wondering if they're actually good for beginners or if I should just try making my own substrate first.

Yeah, I got one of their all-in-one bags a few months back. They're super straightforward. Comes with pretty clear instructions too, so you don't really have to guess.

Honestly, for a first timer, those kits are perfect. Takes a lot of the hassle out of it. Plus, their substrate bags are sterilised properly, which is key.
