Premium XL Liquid Culture Kit – 28oz

Turn One Spore Syringe Into 40+ | Accelerate Germination & Cloning

Maximize your spores and dramatically speed up colonization with our Premium XL Liquid Culture Kit. Designed for growers who want efficiency, scalability, and reliability, this 28oz sterilized liquid culture system transforms a single spore syringe into vigorous liquid mycelium—ready to inoculate up to 40+ spawn bags or 160 half-pint jars.

Simply inject 3–5cc of spores (or introduce a clean agar wedge), incubate, and watch dense mycelium develop in just days. Once colonized, draw into the included 60cc syringe and scale your grow operation with precision.

Why Growers Choose This Kit

  • Multiply One Syringe Into 40+ – Turn a single spore syringe into dozens of inoculations.
  • Faster Colonization – Liquid mycelium shaves over a week off grain colonization times.
  • Cloning Made Simple – Expand your favorite genetics cleanly and efficiently.
  • Professional Lid Upgrade – Dual-layer, high-density 0.22 micron waterproof filter reduces contamination risk.
  • Built for Scale – 28oz volume gives serious expansion potential without complex equipment.

What’s Included

  • 28oz Pressure-Sterilized Liquid Culture (in 32oz glass jar)
  • Proprietary 3.8% Nutrient Blend – Distilled Water, Dextrose, Extra Light Malt Extract, Soy Peptone
  • Dual-Layer 0.22 Micron Waterproof Filter Lid

  • Magnetic Stir Bar + High-Power External Magnet
  • Large 60cc/mL Luer Lock Syringe

Easy Steps

  1. Inoculate with 3–5cc of spores or add a clean agar wedge.
  2. Incubate at 76–82°F.
  3. Watch Growth – White mycelial clouds typically appear within 4–5 days.
  4. Stir Regularly using the magnetic system to promote even development.
  5. Draw & Inoculate – Use the 60cc syringe to expand into grain jars or spawn bags.

Unused culture can be stored in the refrigerator for up to 3–4 months.


Why Use Liquid Culture?

  • Speed – Faster colonization compared to direct spore inoculation.
  • Efficiency – Expand limited genetics into large production runs.
  • Consistency – Even distribution of live mycelium improves success rates.
  • Cost Savings – Dramatically increases yield per spore syringe.

Important Notes

  • Best used within 2–3 weeks of arrival.
  • Store refrigerated before and after use.
  • Inspect upon arrival — we guarantee replacement if jar is damaged or leaking.
