Elm Oyster Liquid Culture

By TS Whiterock

Unique in flavor, bold in structure, and brilliantly fast to grow — TS Whiterock’s Elm Oyster (Hypsizygus ulmarius) Liquid Culture is a refined choice for cultivators who value both form and function.

This is a first-generation liquid culture, developed directly from verified agar plates to ensure the purest possible genetics. No reculturing, no degradation — just clean, vigorous mycelium ready to thrive.

Our culture features pre-germinated live mycelium, suspended in a nutrient-rich medium that bypasses the germination phase entirely. That means faster colonisation, lower contamination risk, and reliable, consistent performance from batch to batch.

Each syringe is lab-tested on agar, guaranteeing only the healthiest, most potent culture reaches your hands.

Why TS Whiterock’s Elm Oyster Stands Out:

Live, First-Gen Mycelium – Straight from agar for strength, purity, and speed
Colonises Fast – Typically ready to take over your substrate within 14 days
Lab-Tested Purity – Each batch is screened for cleanliness and vitality
Pre-Germinated & Potent – Skip spores, start with thriving mycelium
Guaranteed to Fruit – No mushrooms? We’ll send a free replacement
