The 6mm punch is standard for inoculating grain bags and small jar vessels through self-healing injection ports. The 10mm punch suits denser transfers — bulk substrate, larger LC vessels, or moving a known-strong sector onto a fresh agar plate. Starting out, the 6mm is the more versatile first purchase.

Beads calibrated to 250°C deliver consistent sterilization every dip. Safer than open flame near isopropyl alcohol on the bench, and practical indoors without an open flame or fuel canister. The quality-of-life upgrade once agar work is routine.

GL45 is the standard thread for laboratory glass bottles. The ported cap adds barbed connectors so silicone tubing runs in and out of a sealed sterile vessel. Combined with a magnetic stir plate, a GL45 bottle becomes a liquid-culture multiplication vessel — the standard scale-up path for any cultivator multiplying their own LC.

A kitchen pressure cooker works for a few jars at a time. The Steam Sterilizer 3030 is sized for routine bench work — multiple jars or LC vessels at once, longer cycles, more precise temp hold. Next step up: the 55-gallon barrel steamer for production fruiting-bag substrate.
