Fresh sprouts every week — without the daily rinsing.
Manual sprouting sounds simple — until life gets in the way. AutoSprout removes the daily chore, so you get fresh sprouts without the constant remembering.
What’ included?
Why most people stop sprouting
Manual sprouting sounds easy, but it comes with a hidden cost:
you have to remember to rinse, be home every day, monitor the batch, and keep the process going. Miss a day, and the routine breaks. Sometimes the batch does too.
AutoSprout removes that friction. No daily rinsing. No moldy jars. No babysitting. Just set it up, let it run, and harvest when ready.
AutoSprout is not the cheapest way to sprout. It is the easiest way to grow large amounts of fresh sprouts consistently at home — without daily rinsing, failed batches, or paying premium prices for store-bought sprouts.
A one-time investment used across up to 60 batches / year brings the cost per batch remarkably low — not just for one season, but potentially for many years of fresh sprouts at home.
At up to 500 g / batch, AutoSprout can produce up to 30 kg / year. Buying that amount fresh can easily run into the thousands — if you can even find consistent organic quality locally.
Manual sprouting means 2 rinses / day for 3–6 days / batch — up to 12 rinses per cycle, plus draining, monitoring, and cleaning. Miss one rinse and the batch can be compromised.
Based on up to 500 g yield per batch and up to 60 batches per year. Actual yield varies by seed type, growing conditions, and user routine.
Light, misting & drainage fully automated until harvest.
Separate clean & waste tanks, optimized misting cycles.
No plastic in the seed contact path.
Compact, portable, Norwegian-designed.
Yes, we only use best in class food safe materials!
The plastic we use (ABS PA-757KF) is certified food-safe. It has been tested by TÜV Rheinland under strict EU and German standards for food contact. The tests were done with water, oil, and acidic solutions at high temperatures (10 days at 40 °C) – conditions much harsher than how AutoSprout is used.
All results passed with a wide safety margin:
No BPA or phthalates
No harmful leaching of chemicals like acrylonitrile or butadiene
No polycyclic aromatic hydrocarbons (PAHs) detected
Well below EU migration limits for metals and organics
Since AutoSprout only uses fresh cold water during sprouting (3–6 days), the safety margin is even higher.
👉 The real food safety focus isn’t the plastic – it’s keeping your sprouts fresh and clean. That’s why we recommend:
Rinsing and cleaning the machine between each cycle
Using high-quality sprouting seeds
Checking sprouts daily for freshness
Sprouts are packed with fiber, enzymes, vitamins, minerals, antioxidants, amino acids, and bioactive compounds, which makes them a natural supplement that has been shown to reduce inflammation in the body.
