THE HARDWARE
The version of sprouting that actually works.
Most people who quit sprouting quit because it molded or rotted in a jar. The Sprouter is built to prevent that, and it takes about two minutes a day.
Airflow and full drainage stop the mold and rot that end most DIY sprouting.

It sits out on your counter, so the habit stays in front of you.
Works with all 12 of our seed varieties.
How it works
3 easy steps to your homegrown superfood.
1
Soak
Add seeds to the sprouter, cover with water, soak 8–10 hours (overnight).
2
Rinse
Rinse and drain twice a day. Watch sprouts emerge in 5-6 days.
3
Harvest
At 1–3 inches, rinse, dry, and pile them onto anything.

THE SCIENCE
One compound. A quarter-century of research.
When you sprout our Organic High-Glucoraphanin Broccoli Seeds, they produce sulforaphane, one of the most studied compounds in nutrition science. It works by activating Nrf2, your body's own cellular-defense system.

Your cellular defenses
The precursor becomes the compound the moment you sprout and eat it. Fresh sprouts bring what your body needs to make the conversion.
01
How sulforaphane works
The switch that turns on your body's own defenses.
Your cells come with a built-in defense system governed by a protein called Nrf2. Most of the time it sits quiet. Sulforaphane activates it, signaling your cells to make their own antioxidant and protective enzymes. That is the difference between swallowing an antioxidant and growing one:
an antioxidant you take neutralizes a single molecule and it is gone, while sulforaphane supports your body in producing its own defenses, on its own schedule. Sulforaphane is not ready-made in the seed. It forms when you sprout, as glucoraphanin meets the enzyme myrosinase the moment a fresh sprout is chopped or chewed.
Mechanism
02
Where it starts: broccoli sprouts
One of nature's richest sources of the precursor to sulforaphane.
In 1997, Johns Hopkins researchers showed that three-day-old broccoli sprouts carry far more glucoraphanin, the precursor to sulforaphane, than mature broccoli. It's the study the whole field is built on. It's also why we grow the seeds we do: ours are selected for nutritional output, so a fresh harvest can deliver up to 100x more glucoraphanin than a head of store broccoli, grown by you, hours from your plate.
03
Measured in a clinical trial: everyday pollutants
Sprout-eaters cleared the pollutant benzene 61% faster.
In a 12-week randomized, placebo-controlled trial of 291 people, those who drank a broccoli-sprout beverage excreted the airborne pollutant benzene 61% faster than the placebo group. The effect appeared on day one and held for the full twelve weeks. It's the Nrf2 pathway, measured in real people, the body's own defense enzymes doing their work.
04
Measured in a clinical trial: healthy glucose metabolism
Concentrated broccoli sprouts supported healthy fasting glucose.
In a 12-week randomized, placebo-controlled trial, concentrated broccoli sprout extract was well tolerated and supported healthy fasting glucose, working through the same Nrf2 pathway. As with everything here, sprouts are food, at their best as part of a balanced diet. This is support for a healthy system, not a substitute for one.
05
The depth of the research
25+ years of study. Dozens of human trials.
Sulforaphane is one of the most studied compounds in nutrition science: more than 25 years of peer-reviewed research and dozens of registered human clinical trials, much of it out of Johns Hopkins. Dr. Jed Fahey, who helped pioneer this work, sits on our Scientific Advisory Board. The science didn't start with us. We just made it something you can grow.

Sulforaphane is the reason to start. Taste is why you keep going. Fresh sprouts are crisp and a little peppery, and they are good on almost anything: salads, grain bowls, avocado toast, tacos, soups, even a smoothie. And since you can grow different varieties, it does not get boring.

THE SPROUT KING
Hi I’m Doug.
Thirty years ago I started sprouting and never stopped. I wrote The Sprout Book because I believed anyone could do this, then built the sprouter because the tools kept failing people who tried.
No land, no sunlight, no experience. A couple minutes a day on your own counter. Let's grow!

FAQs
What are sprouts, exactly?
A sprout is a seed that has woken up. Give a dry seed water and a few days, and it starts building a plant: growing a root, unfurling a stem, and synthesizing nutrients it never had while it was dormant.
You eat the whole thing, seed and stem and all, usually three to five days in. No soil, no sunlight, no garden. Just seeds, water, and about a minute of your attention twice a day. Welcome to one of the most nutrient-dense foods on Earth!
Do I need a green thumb, a garden, or a sunny window?
None of the three. Sprouting happens indoors, in water, on a countertop, and sunlight is not part of it.
If you can rinse a colander, you can do this. That is the whole skill.
How much time does this take every day?
About a minute, twice a day. You rinse, you drain, you walk away.
Most people fold it into things they already do. Rinse when the coffee is brewing, rinse again after dinner.
Which seed should I start with?
If you are here for the nutrition, start with High-Sulforaphane Broccoli. It is our most researched seed and the reason most people find us.
If you want something that goes on everything and pleases everyone at the table, start with High-Sulforaphane Salad Mix. Broccoli, radish, mung beans and green lentils in one harvest, so you get variety in texture and flavor without running two batches.
If you want protein, start with Lentils or Green Peas. They are also the fastest, which makes them a satisfying first win.
What is the difference between sprouts and microgreens?
Sprouts grow in water, take three to five days, and you eat the entire plant including the root and seed. Microgreens grow in soil or a growing medium, need light, take seven to fourteen days, and you cut off the top and leave the roots behind.
Sprouts are faster, need less equipment, and give you more food per square inch of counter. That is why we build around them.
Will I actually stick with it?
More people do than you would expect, and the reason is that the feedback loop is fast. You see visible change every single day, and you are eating the result inside a week. Most healthy habits ask you to wait months for a payoff you cannot see.
The system is built for the sticking part too. The sprouter sits on your counter where you cannot forget it, and the daily job is small enough that skipping it never feels worth it.
