Why growers start on MEA

  • Spore germination – An excellent first plate for spores and early-stage culture work.
  • Balanced nutrition – Supports clean, steady mycelial expansion.
  • Easy contamination checks – A reliable baseline that makes contaminants easier to spot.
  • Consistent fills – Machine-poured at 20 mL per plate for repeatable results.
  • Color-coded – Green, blue or pink plates, randomly chosen, help with organization and quick batch ID.

What's included

  • 5 pre-poured, sterilized MEA plates (90 x 15mm, 20 mL each) in assorted colors, sealed in polyolefin packaging

How to use agar plates

  1. Work clean. Open plates only in front of a flow hood or inside a still air box.
  2. Inoculate. Add a small drop of spore solution or liquid culture, or a small piece of tissue, to the agar.
  3. Seal. Wrap the edge of the plate with lab poly film.
  4. Incubate. Within days, mycelium begins to spread across the surface.
  5. Transfer. Cut a clean wedge with a sterile scalpel and move it to a fresh plate, grain jar, spawn bag or liquid culture.

Workflow tip: Start spores on MEA to evaluate cleanliness, transfer clean sectors, then finish on Rapid Rhizo when you're ready to showcase your strongest genetics.

Which agar plate should I choose?

Agar type Best for Why growers use it Stage
Regular LME / MEA (this listing) Spore germination, first plates, contamination checks Reliable baseline media that makes early growth and contaminants easier to evaluate Start here → first transfer
Rapid Rhizo 2nd and 3rd transfers, clean isolation, showcase plates Encourages aggressive, threadlike growth that's easy to select and preserve After first clean-up → final transfers
Black MEA High-visibility growth, photo-friendly plates, subtle sector spotting Dark background makes mycelium edges, sectors and early contaminants stand out Any stage, especially evaluation
Manure-enriched conditioning agar Preparing cultures for bulk substrates, performance testing Conditions cultures to richer media and shows how genetics behave on supplemented nutrition Mid-to-late stage, after a clean culture
