Mr Rogers Labz might be a new name, but it all started in 1999! I was fresh out of high school, telling my buddies about these books I found at the local head shop. Paul Stamets became my everyday reading material, over and over!! My first kit came from homestead, and I was hooked.  I couldn’t afford a pressure cooker at the time. So my friends all got together and bought me one hoping I could back up all this talk I was talking! The rest is history. Thank you for checking out my store!

Amazing quality

I haven’t been this happy from opening up a package in so long! I received an almost fully colonized bag and they threw in a free agar plate! Absolutely wonderful service. Thank you!


AMAZING VENDOR!

Vendor was awesome -- great communication, super responsive, answered all my questions and more. Had a great deal for $25 colonized grain spawn -- got to expand my genetics library for just barely more than the cost of most syringes or plates, and got a huge head start to fruiting at the same time?! Sign me UP! Everything he's sent has been a banger, and he's been generous with freebies and slaps. 11/10 - will buy again and frequently

Prompt/knowledgeable service, shipping, and amazing/generous products

Packaged discretely and securely. Vacuum sealed. Perfectly colonized and ready to go! On top of what I ordered Mr Roger's threw in a free anubius spore swabs, and another strain spore print for completely free! Cool free stickers, also!This was my first time trying to grow myceillium at home I asked for them to choose strain best for a beginner. I got Hillbilly. I had no idea what I was doing. Grew it i a mono tub that sat within a bigger plastic tote about a foot from my spare bedroom wall register. I thought I messed up a dozen times, but after a couple weeks I was swimming in fruit! Plan to be a long time customer! Thanks Mr . Roger's!!!


Perfect! + free swab!

Mr Roger's is my new favorite. Ive recently purchased several fully colonized from a variety of sources. This showed up 👌 clean, full, no piss (although thats not always a bad thing.) Just as advertised s2b without having to wait. However, im a weirdo and make soup outta it for some guinea pigs to chow down on. Edit: ordered 11/20. Harvest 12/31. Project Blue Beam. Fruits look like pics. Awesome, contam resistant, fast.
