Growing Sprouts at Home FAQS

There are a couple of questions that come up a lot, especially with beginners who are just starting to grow sprouted seeds at home. So we thought we'd put them together for people to read. Hope you find it helpful.

We’ll use the word ‘seed’ for all seeds, beans, legumes and grains.


Soak the seeds for 12 hours (except for gelatinous seeds which should not be soaked.) The initial soak starts the germination process which makes the seed sprout. The number of hours does not have to be exact. 

If the seeds have a poor germination rate, soak the next batch for 24 hours with a change of water at 12 hours. 

Some beans, ex. Adzuki benefit from 24 hours soak time. If using a mix which includes adzuki, soak the entire mix for 24 hours.

Gelatinous seeds do not need to be soaked, just start the sprouting process. (These include arugula, chia, and flax seed)


Rinse and drain the seeds twice a day, more often if they are looking dry. Fresh, cold tap water is fine. Make sure there is no standing water, the seeds should be wet but not sitting in water. 

If using a mason jar, tilt the jar at an angle, lid-down, so water continues to drain.

Cilia Hairs

If the sprouts become dehydrated, they may grow ‘cilia hairs’ these are tiny cells which take water from the air. Cilia hairs are white and do not smell. 

Simply soak the seeds to rehydrate them and drain the water as usual, the cilia hairs will disappear.


If you follow safe food-handling and spouting directions, mold is unlikely. You can recognize it by the odor and appearance, it may be a dark color with a slimy texture and smell bad. If you rinse the sprouts, it will not disappear. 

Throw the sprouts away, thoroughly wash all equipment and start a new batch.

Green Up

When the leaves appear on leafy sprouts, put them near a window (gentle sunlight) so they can create chlorophyll, this makes them even more nutritious. 

Do not let them get too hot, because they will ‘cook’.

Harvest Time

Leafy sprouts are ready when they have two tiny leaves. Beans and legumes are ready when they have a small root before they grow a leaf or stem. 

If the sprouts grow a little more, they are still edible, but they may not be as tasty. 

Do a taste test to decide when to harvest them.


Sprouts can be stored in the fridge like any other salad. If they dry out, give them a soak and rinse. 

Like all other salad, they are best eaten when they are fresh.
