A clean liquid culture media in pre-measured packets, built for gourmet and medicinal species alike. One packet makes a 600ml jar, the right pour for a standard wide-mouth quart. No scale, no measuring, no guesswork. Just add water, sterilize, and go.

Here's why premix instead of a finished kit: you make it yourself, for a fraction of the cost, as many times as you like. A single packet turns into a full quart of live culture for around a dollar. And because it ships dry, it keeps. No pre-hydrated media sitting around clouding up on a shelf, waiting to let you down.

Good for

• Restocking after your LC starter kit

• Expanding cultures from strains you already trust

• Building master culture stock for the long haul

• Inoculating grain spawn without the fuss

• Keeping an active culture library topped up

What you get

• Single-dose packets, one per 600ml jar, so there's nothing to measure and nothing to get wrong

• A lean, three-ingredient formula that gives mycelium what it needs and skips what invites contamination

• Individual packets, use what you need and keep the rest sealed and fresh

• Works across the board, gourmet, medicinal, and specialty species

• Dead-simple prep: add to water, stir, sterilize. Tap water works, though cleaner water works better.

Pick your size

• 5 packets, $7. A good first try, five quarts of culture.

• 10 packets, $12. The steady-grower pack, and a better price per jar.

• 20 packets, $20. A buck a jar, for when culture work is just part of your routine.

Why lean beats loaded

A lot of formulas pile on sugars and long ingredient lists that read impressive and feed contamination just as happily as they feed mycelium. I went the other way. Three ingredients, each one there for a reason, in ratios I dialed in through my own grows. This is the exact premix I use in my own lab, because a clean culture matters a whole lot more than a fancy label. Made by a working

mycologist, not a marketing team.

Keep your culture work moving, one clean jar at a time.
