Advanced Growing & Lab Supplies

You know your way around a grow. This is where to go for living genetics, fast bulk scaling, specialty species, and building out your own sterile lab. Pick a lane below.

Colonized Plates & Cultures

Start from clean, living genetics

  • IncludesAgar plates, slants, LC
  • Best forIsolations & library
  • Strains10+

Fully colonized agar plates, live cultures on slants, and the Active Air liquid culture system give you clean, isolated genetics to build from — expand a strain, run isolations, or keep a living library with none of the spore variability.

Colonized Grain Spawn

Skip colonization, scale up fast

  • Includes5 LB & 3 LB bags
  • Best forBulk fruiting
  • Varieties15+

Fully colonized grain spawn, ready to break and mix straight into bulk substrate. It removes the slowest, highest-risk steps — inoculation and colonization — so you can run bigger cycles across 15+ gourmet and functional varieties.

Agar & Lab Supplies

Pour and transfer your own

  • IncludesMedia, plates, tools
  • Best forDIY agar work
  • ToolsScalpels, punches, film

Everything to run your own agar bench: LME and pure agar powders (200+ plates' worth), pre-poured Black MEA and manure-enriched conditioning plates, malt-extract slants, sterile scalpels, 6mm punches, and poly film. Pour, cut, transfer, and store your own genetics.

Grass Lover's Kits

For demanding grass-loving species

  • IncludesBulk spawn + casing
  • Best forGrass-loving types
  • SubstrateManure/grass, cased

Grass-loving species need a manure-and-grass substrate and a proper casing layer — very different from wood or bulk gourmet growing. These Complete XL bulk spawn + casing kits (plus refills) are dialed in for that species group, so you're not improvising the substrate.

Flow Hoods & Clean Room

Build your own sterile workspace

  • IncludesDIY kits, hoods, FFUs
  • Best forIn-house sterile work
  • OptionsBuild or buy complete

Take contamination control in-house. Grab a Bonsai DIY blower + HEPA filter kit to build a flow hood to your own frame, or go with a complete 99.99% HEPA laminar hood or fan filter unit for a ready-made clean-air zone for agar, LC, and spawn work.
