A grow in four steps

You can join the chain anywhere. Most first-time growers should start at step two.

STEP 1

Culture

Start from an agar plate or a live liquid culture.

STEP 2

Colonize grain

Or skip ahead — buy grain spawn already fully colonized.

STEP 3

Mix to bulk

Break the spawn into CVG substrate and let it run.

STEP 4

Fruit & harvest

Light, fresh air, humidity — then it all happens at once.

Not sure what you actually need?

The most common way a first grow fails is buying the wrong step in the chain. Tell us how much sterile work you want to do and we'll point at one thing — not ten.

All four all-in-one grow bags are sold out right now

They're made to order, so they go out of stock while a line is rebuilt at the bench. Colonized grain spawn needs no sterile technique either — it's the honest substitute until the bags are back.

Why buy from a lab, not a shelf

Laminar flow prepared

Filtered, unidirectional air over every open vessel.

Made to order

Assembled after you buy — not months before.

Lab-tested

Checked for contamination before it leaves the bench.

Vacuum-sealed for transit

Arrives as clean as it left the lab.

Shipped across Canada

Out of Alberta, to any province.

Straight guidance

We'll tell you if you don't need the expensive thing.

What we actually promise

Four things we'll put in writing — and one we won't pretend about.

It was made for your order

Not pulled off a shelf where it had been sitting since spring.

It was prepared under a flow hood

Every open vessel sees filtered, unidirectional air.

It was checked before it shipped

Contamination gets caught here, not in your tent.

We'll talk you out of an upsell

If a $39 bag does what you want, we say so.

What we won't promise: a guaranteed harvest.

Nobody honest can. Your temperature, humidity and fresh-air exchange decide the grow — we control what leaves the lab, and we tell you the rest straight.

Common questions

I've never grown anything. Where do I start?+

Colonized grain spawn plus a bag of CVG substrate. There's no sterile work for you to do — you break the spawn into the substrate and manage humidity and air. All-in-one bags are the other beginner route, but all four are sold out at the moment.

What's the difference between liquid culture and grain spawn?+

Liquid culture is live mycelium in nutrient broth — you inject it into sterilized grain yourself through a self-healing port. Grain spawn is that step already done and fully colonized, ready to break up and mix into bulk.

Do you ship outside Alberta?+

Yes — Canada-wide. Everything is vacuum-sealed before it leaves the lab so it arrives in the condition it was packed.

Why is something showing as sold out?+

Because it's made to order rather than stockpiled. When a line is being rebuilt at the bench we mark it sold out instead of shipping something we're not confident in.
