⭐⭐⭐⭐⭐

After 3 days, Much Greener and filled in

Debbie M.

⭐⭐⭐⭐⭐

I wanted something that would work but not expecting this. After using trout boost my flowers in all my pots are so bright, fuller and taller after 1 day!

Nathan J.

⭐⭐⭐⭐⭐

Works extremely extremely fast 24hrs. This is what happened from seed, the results have been incredible. in less then 24 hrs. my seeds have rapid germination, and if I leave them any longer the roots will actually start growing into the paper towel its extremely potent, I'm very impressed with the speed and performance, ill definitely keep using Trout Boost!

Jenn P.

⭐⭐⭐⭐⭐

I've tried several organic fertilizers over the years, but this one produced the best results. I treated my soil and watered with black label and this happened, thank you

Yonna

⭐⭐⭐⭐⭐

My tomato plants in less than 5 days using Trout Boost! so happy I found this, I will be using on my whole yard!

Jim H.

⭐⭐⭐⭐⭐

I would like to give a review, I got Black Label from you and add it to my teas that I use in my living soil beds and after 2 days being applied I noticed a difference. they are a more vibrant, they respond faster to topping. I think I found my winner

Why it works

What Trout Boost does.

It's the same biological signal soil has been waiting for since long before bagged NPK existed.

  • Fuels microbes

    Living biology — the part bagged fertilizer can't deliver.

  • Strengthens roots

    Bioavailable nitrogen and trace minerals plants actually use.

  • Raises organic matter

    Builds soil structure season over season, not just one bloom.

  • Outperforms synthetics

    Side-by-side trials in five Colorado counties since 2019.

From trout farm to soil

Our process.

Clean, simple, and built on purpose.

  1. 1

    Raised with care

    Healthy trout in clean, spring-fed pools.

  2. 2

    Nutrient-rich effluent

    Naturally rich water flows from our springs.

  3. 3

    Filtered naturally

    Solids are removed using mechanical filtration.

  4. 4

    Lab tested

    Tested for quality and consistency.

  5. 5

    Bottled with care

    Packaged on-site to preserve freshness.

  6. 6

    Poured into soil

    You feed your soil. Your soil feeds your plants.

ABOUT US

We're a family of five, and about 18,000 rainbow trout.

Fish Fin Farms is a family-owned Rainbow Trout Farm in Colorado, built around a simple belief: some of the best solutions are already found in nature.
Trout Boost started because we noticed the grass downstream of our pools grew taller, greener, and tougher than the rest of the field. Turns out trout know things about soil that we forgot.
We feed our trout, the trout feed our soil, and the soil feeds whatever we plant.
We use Trout Boost ourselves. We see where it comes from, we know how it’s made, and we’re proud to put our family’s name behind every bottle.
We’re not a big company. We’re a family farm that raises trout and believes good soil deserves a more natural approach.
Raised. Made. Bottled. By our family.

Frequently asked

Questions, answered.

Will it smell?

For about ten minutes, like a farm pond. Then it disappears completely as soil biology metabolizes it.

Is it safe around pets and kids?

Yes. Trout Boost contains nothing your dog couldn't drink. We still recommend washing harvested produce.

Can I use it with synthetics?

You can — but you usually won't need them within two seasons. Microbial soil unlocks nutrients that bagged fertilizer just hands you.

How long does a bottle last?

The 1-gal treats up to 16,000 sq ft for a full season; 2.5-gal covers 40,000; 5-gal covers 80,000. That's less than $0.01 per sq ft

Do you ship outside the US?

Not yet. Shipping liquid across borders is hard. Subscribe to our list — we'll announce when we expand.

How do I cancel my subscription?

One click in your account. Skip, pause, or cancel any time. We never charge cancellation fees.

Why it works

What Black Label does.

Black Label is the unfiltered cut — every natural solid left in. Not a fertilizer, but the full biological signal your soil has been waiting for.

  • Fuels microbes

    Living biology — the part bagged fertilizer can't deliver.

  • Strengthens roots

    Bioavailable nitrogen and trace minerals plants actually use.

  • Raises organic matter

    Builds soil structure season over season, not just one bloom.

  • Outperforms synthetics

    Side-by-side trials in five Colorado counties since 2021.

What's in the bottle

Why Black Label works.

The unfiltered, super-concentrated cut of Trout Boost — everything that matters, straight to your soil.

  • Lab tested

    Every batch

    Independently verified by Tri-Rivers Labs. Scan the QR on every bottle.

  • Trout sourced

    18,000 fish

    Spring-fed Colorado pools. Naturally settled effluent — never scraped.

  • Unfiltered & raw

    Full solids

    Nothing strained out. Every natural solid stays in — the complete biological and organic payload.

  • High strength

    1 oz / gal

    Super-concentrated. One ounce makes a full gallon of working solution — a little goes a long way.

Montrose, Colorado · Est. 2019

We're a family of five. And about 18,000 rainbow trout.

Trout Boost started because we noticed the grass downstream of our pools grew taller, greener, and tougher than the rest of the field. Turns out trout know things about soil that we forgot.

We feed our trout, the trout feed our soil, and the soil feeds whatever we plant — that circle is the whole product. There's nothing here we invented; we just bottled what was already happening downstream.
