Beetroot is a more challenging microgreen to grow due to its tough seed hull. Each seed is actually a cluster of several seeds. Beet greens are highly nutritious and are very colourful and flavourful.
Soak in plenty of water for 12 - 24 hours.
Prepare your Nubox surface ensuring to leave aside about ¼ of the coco soil.
Sow the seeds on your prepared Nubox surface. Cover the seeds with the remaining coco and cover with a very moist paper towel. Place a heavy weight in your top tray and leave for 4 to 5 days until the seedlings have built a good root system.
On day 4 or 5, remove the weight and flip the top tray to create a blackout dome. Leave for one day to allow seedlings to straighten up and stretch slightly.
After 24 hours place your Nubox on a sunny windowsill or under another lightsource.
Bottom water by lifting the green tray up and pouring approximately 100ml of water into the base tray. Wait 10 minutes for the water to absorb fully before deciding to add more.
Be careful not to overwater as waterlogged roots will kill off your plants.
Harvest from day 12 onwards.
Remove any remaining seed hulls as these are very hard and not pleasant to bite down on.
