    Instructions:

    Soak the seeds in plenty of water for 6 - 12 hours. 

    Sow the seeds on your prepared Nubox surface, cover with a thin layer of coco coir and finally cover with a very moist paper towel. Place a weight in the top tray. Leave for 3 to 4 days until the seedlings have built a good root system and are about 1cm in length. 

    Onion seeds are susceptible to mold. We therefore recommend the use of hydrogen peroxide or another mold remedy for these microgreens. 

    On day 3 or 4, 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 14 onwards.
