Sprouting is both fun and easy but if you do have any problems, our troubleshooting guide should give you a helping hand in growing your own tasty sprouts, the right way!
Remember! Germination is a natural process that depends on the right supply of moisture, light and air.
Seeds will not sprout if…
- The seeds are too densely sown
- The seeds are not watered carefully or are watered too often
- The ambient temperature is too low or too high during germination
Seeds don’t sprout
Why: Too many seeds in the germinator or not enough watering
What to do: Stick to the recommended amounts (see seed packet). Spread the seeds out evenly at the start of the process, and after each rinse. Make sure you soak seeds overnight and rinse and drain them twice a day.

Sprouts taste bitter
Why: Sprouts have been left too long before eating
What to do: Harvest sprouts a little earlier for a sweeter taste.
Sprouts go off, develop mould or rot
Why: Possible causes include the room being too warm, insufficient rinsing and draining or the germinator not being cleaned properly between batches
What to do: Make sure the room is not too warm. Make sure the seeds are rinsed daily and drained well. Clean germinator thoroughly.
Water does not drain properly through large germinator
Why: Red plugs are clogged or directly above each other
What to do: Stagger the red plugs (don’t have them directly above each other). Check the plugs are not clogged. Make sure the plugs are not pushed in too hard.
