WBS tek complete walkthrough — wild bird seed from prep to fruiting
44 replies · Cultivation
Wild Bird Seed tek is genuinely the easiest grain spawn preparation for beginners. I've done over 100 WBS jars and want to document my entire process. WBS advantages: it's available at any garden store or Walmart, cheap ($5-15/bag), pre-mixed grains provide diverse nutrition, and it tolerates a slight under-sterilization better than rye. Here's my complete process.
Prep: rinse WBS thoroughly until water runs clear. Soak overnight (8-12 hours) in water. Drain and simmer (not boil) for 10-15 minutes until grains are slightly swollen but not burst. Spread on baking sheet and let steam out for 20-30 minutes until surface-dry but not desiccated. Too wet = contamination. Too dry = slow colonization. Grain should feel like a good handshake — firm but not rock-hard.
Sterilization: fill mason jars 2/3 full with prepared WBS. Tighten lids finger-tight, wrap tops in foil. PC at 15 PSI for 90-120 minutes. Let cool 12-24 hours before inoculating. Never inoculate warm jars — heat creates condensation and contamination.
Inoculation via spore syringe: flame sterilize needle until red hot. Cool 3-5 seconds. Inject 1-2ml against the glass wall at multiple points. The self-healing injection ports (silicone) are worth it — they let you inoculate without opening lids. Shake jars after inoculation to distribute spores across grain surface.
Contamination is the #1 failure mode. When in doubt, throw it out. Don't open questionable jars to smell or inspect — you'll just spread contamination. A contaminated jar in a tub can ruin 10 other jars. The economics of cultivation favor aggressive contamination disposal over trying to save jars.
