Seeding & Sprouting

Let's collect all relevant information about success, failures and improvements here.

Mung Seeds

Mung seeds have been selected as the first test candidate because they don't require to be cooked in order to become edible (some sprouts do), offer a great range of vitamins and minerals and should be easily obtainable everywhere.

Level Container type siphon?
Beginner seedstack-container.stl Yes

The seeds have been completely submerged in room temperature tap water for about 8 hours in a cup, then put into the seedstack container. The seeds will sprout without this step, however, giving the seeds 8 hours in water seems to have an effect on the overall mass the sprouts will yield.

After putting the seeds into the seedstack container, they need to be flushed twice per day (morning/evening). To flush the seeds, about 500ml of water are poured into the topmost container (if you have more than one) and will drain automatically at the bottom of the container through the syphon. This might also be a good job for an Arduino controlled valve/pump.


First flush with the original (red) siphon.


The siphon was changed to the new printed (black) one and flushed again. Siphon operation test successfully concluded, almost all seeds have cracked their shell and begun to sprout already.



Black lentils

Level Container type siphon?
Easy seedstack-container-lentil.stl No
  • Notes: Top layer tends to sprout first, recommended you remove first layer when matures so lower levels can grow.
  1. Soak overnight the seeds
  2. Put seeds in appropriate seedstack container
  3. Water twice a day (eg morning and night).
  4. Let water drain out
  5. When not watering place container in a dark place
  6. Thats it!

Known not to sprout

Here are list of beans we tried, but would not sprout using the normal treatment, if you have any advice please open an issue in the issue tracker.

  • Chickpeas - Will not sprout at all
  • Black beans - Will sprout partly, tested with Mung watering instructions
