These pre-poured sterile agar petri dishes are ideal for early-stage fungal culture work, including cloning wild mushroom specimens, germinating fungal spores, and cleaning up contaminated samples. Each dish contains pre-sterilized potato dextrose agar (PDA) supplemented with a selective antibiotic and a blue stain that improves visibility of mycelial growth.
Blue Antibiotic Agar Plates are designed to help suppress bacterial contamination during first transfers and initial isolation work. The blue tint enhances contrast, making mycelial edges easier to see and evaluate while working through unsterile material.
Pre-poured agar plates offer many benefits over pouring your own dishes. In addition to convenience, they are also less likely to contaminate your cultures because they are poured in a lab under an industrial-grade flow hood.
Use Blue Antibiotic Agar Plates for early cleanup passes and first transfers from wild or dirty samples. After achieving clean growth, step down to standard agar to confirm long-term culture health and purity.
For best results, use plates as soon as possible after receiving them. Store unused plates upside down in a refrigerator in the original packaging.
Once cultures are added, incubate at room temperature until the new plate is fully covered with mycelium. Once fully colonized, store plates right side up in the refrigerator until ready to use (except for cold sensitive species).
Antibacterial agar helps suppress bacterial hitchhikers during early transfers. It's ideal for first passes on wild or unsterile samples.

Reduce contaminants when you mix or inject substrate
We recommend absolute beginners start with our Spray & Grow Kits, which make growing mushrooms at home super easy.
We want you to have the best possible experience with every North Spore product and guarantee free replacements within 30 days of receipt for any damaged, contaminated, or unusable product.
Absolutely! Mushroom cultivation is a great activity to do with the whole family, whether you'd like to grow indoors or outdoors. If you're new to mushrooms, we recommend starting with a Spray & Grow Kit or a Plant & Grow Kit – both make it easy to grow fresh, organic mushrooms at home.
We are vertically integrated — from culture work all the way to spawn and substrate production — ensuring a quality end product. And our staff mycologists keep up to date on all best practices in our field. Additionally, we have a dedicated QAQC team that tests every batch of grain and substrate before it’s inoculated.
Whether you’re growing mushrooms at home, in your garden, or at a commercial scale, we offer everything you need to cultivate success. We start with the highest-quality OMRI-listed ingredients, mix them in our state-of-the-art facility, and inoculate them in our custom-built lab, so you can rest easy knowing your product will yield the best results.
Very impressed with the quality! Thank you North Spore
We appreciate your support, Justin! Please reach out if you ever need anything.
Thanks for quickly getting the remainder of my agar plates to me! You guys are great to work with!
I really enjoyed the quality of this product, so i had to come back for a 2nd purchase! I also appreciate and respect the customer service team for helping me track my order correctly!
Very interesting product, with a bit of R&D along with some Lab work the reaults were very fascinating!
Theae are going to be such an amazing thing to use now

This product is a little expensive but for starting out a culture it takes some work out of the process. Use this as a first pass and transfer from this to other plates. This will give your mycelium a leg up while isolating sections.
Warning: may hide contamination so don’t use it to test LC.
Thank you for your review, Jeremy!
Arrived in perfect condition,very well protected...used 5 so far, all clean!!!!
