Parafilm strips, 1″x4″ – pre-cut and conveniently packaged. Used for sealing culture media to allow gas exchange while keeping things out.


Quick Subscription FAQ

“How does this all work?”

It’s as simple as select the items you want, set up payment & enjoy the convenience of automated agar shipments to your door.

“Are these made to order? I don’t want to wait around.”

Your first shipment may be made to order depending on order volume, but we do try to pour extras to keep shipping times low. After your first order, your orders will ship on the date on which you subscribed each month. For example, if you subscribed quarterly on the 1st of the month you would be billed on the 1st of the month every 3 months and your plates will ship on the 1st of every 3rd month from your order date. Keeping in mind that your first order may be made to order and take up to a week, reply to your order confirmation email to let me know if you’re in a hurry!

“What if I want to order 100, or 1000 plates?”

No matter the quantity ordered, shipping will be $10 flat rate, just add 5 of the 20 packs to the cart. Voila! If you’d really like to order 1000 plates, be sure to email us for bulk pricing.

“What if I want to mix?”

Mix away! Remembering that you are ordering 20 packs of slants or Petri dishes, just add & purchase the desired items.

“What if I want a schedule other than advertised?”

Email us! We’ll see what we can do to help.

“Can I store these in the fridge?”

Absolutely! In a sealed container (or ziplock bag), refrigerated Petri-dishes & slants can last for quite some time.

General Product Details

We do offer convenient agar solutions for both home & commercial mushroom growers. In this case, we help remove the hassle of pouring Petri dishes in a still air or glove box, or even for those with flow hoods who are just too busy to make their own plates while running a mushroom farm.

We are happy to help with sterile Petri dishes for culture work and slants for long-term storage of mushroom cultures.

Upon receipt feel free to refrigerate, use when ready to get to work! Add antibiotics to the dishes/slants in the event you’re working with spores, tissue transfers (cloning mushrooms) or are otherwise concerned about bacterial contaminants. For slants, it can’t hurt to have an added layer of protection, but is not necessary!

NOTE: Don’t use antibiotics as a crutch for poor technique, it will bite you in the ass!

Pre-Pours are NOT individualy wrapped, they arrive in 20 packs in sealed gallon zip-locks. If you would like pre-wrapped plates, send us an email for a vendor recommendation!

Some condensate can be expected when conditions outside (during shipping) are not comparable to inside (when you bring the box indoors). To remedy this, after sealing the plates, store them upside down and condensate will dissipate within 1-2 days.

    Amazing product and great customer service will definitely buy again. To be honest I’m making an order as we speak

    It is impossible to leave a review without mentioning the entire Myc Tyson customer experience. I ordered Agar Plates on subscription; not only did I get an email confirming my order, but also notices on when my plates were poured and when they were shipped. I decided to send a quick thank you note to LetsGrow@MycTyson.com and got a real human response and offer for help if I needed any more assistance beyond what was one the website. The plates were see through clear and the customer service is top notch.

    Came in good time with great communication, and were easy to work with and turn into much successful growth! That said, the lids were a bit prone to slipping off at inopportune moments during handling, which was only really any more than a bit of a nuisance due to my own workspace’s size limitations… so this probably is more a me problem, and not a defect as much as a personal preference. I have purchased agar plates from other sellers and while I have received ones with more substantial and better fitting lid situations, these ones performed above and beyond in basically every other way. A little more security around lid snugness or even pre-wrapping would probably push me over the edge, but as it stands, may it be noted that I’m absolutely keeping coming back, and that my real rating would be just shy of 5, not a solid 4. Also one of the plates I got had two ants in the agar, but it didn’t seem to cause any trouble and I misplaced the picture I’d taken of it back when I discovered it first, so, I’m not saying it like it was a big problem at all.

    Outstanding product and truly a revolution when it comes to enabling home mycologists to advance, enhance, and upgrade their study, and ability without any of the compliations. Plus, came with freebies like black agar dishes in addition to more parafilm carefully cut into the perfect size for wrapping dishes. Truly a huge thanks to Myc for this innovation. 5/5 stars as usual.

    Plates arrive well packaged and contamination free each month. Mush appreciation!

  6. Kolya A. (verified owner)

    Nice! I haven’t used these yet, but they arrived perfectly sealed, well-protected, and seemingly very sterile. I’m very pleased with these. There was some condensation which initially caused cause for concern– I’ve never ordered pre-poured before– but it turned out not to be a problem.

    Excellent product and worth every penny!

  7. Jesse N. (verified owner)

    I’m really happy with my plates and the slants – my subscription had an issue, and Myctyson stepped up as he always does. I’m a huge fan of this subscription, they’re high quality, sterile af, and

    Outstanding product. This is the 3rd month i’ve received 40 plates from Mr. Tyson, and not a single one has been contaminated or damaged. They’ve arrived quickly and without any hassle. MycTyson is always my first choice for mycology supplies!!

  9. Tim P. (verified owner)

    Product looks very professional and there was a mistake on my end with the shipping. I messed up and he fixed it right away. Myctyson is the man and I will always go to him first for any mycology needs.

  10. Hieu N. (verified owner)

    A few of my petri plates cracked during the shipment, but I simply emailed Myc about it and he quickly sent me some replacements. And all of those arrived intact. The plates themselves were very easy to use and wrap with Parafilm. I experimented with inoculating from a multi-spore syringe and also cloning from sterile mushroom tissue using a still air box. Both methods seem to be colonizing quickly without contamination! Looking forward to more experiments with agar!
