    Anne Fletcher, founder of Orta Kitchen Garden, has been so incredibly thoughtful with the design and production of this product. She sourced her own clay in order to avoid nasty chemicals (such as Barium carbonate) commonly found in other clays, and she even figured out a way to apply the glaze to her unbaked clay so that she could reduce the number of firings needed for this product from 2 to 1.

    This kit offers a way to grow microgreens with zero waste. The soil/root mat is 100% compostable.

    A small amount of light - either sunshine or daylight (doesn't need to be direct, or intense)


    Hydrate the included soil, and fill the tray with the soil


    Sprinkle seeds, covering with a light layer of leftover soil


    Fill the reservoir with water


    Place in a room-temperature location and wait 7-10 days

    Because terracotta is porous, the water seeps from the reservoir through the terracotta walls to keep the soil evenly moist. Once the seedlings have roots, they can wick as much water as they need.

    Yes. Occasionally it's a good idea to sterilize your pot to prevent diseases and fungi. The easiest method is to scrub all the dirt off your pot with water and a brush. Then put your pot in the oven for an hour at about 180 degrees F (82 C), being careful not to go over boiling temperature (212 F, 100 C), as this can cause trapped water to turn to steam and crack open your pot. The "warm" setting on most ovens works well. It's a good idea to use an oven thermometer to make sure the temperature is right.

    We do not recommend bleach or any other chemicals to clean your pots. 

    These microgreens kits are best suited for herbs or vegetables grown as microgreens (i.e. harvested within 1-3 weeks). If you're looking to establish seedlings for eventual transfer into a larger pot, or the garden, then you might like to consider the seed-starting trays from the same supplier. These have dividing walls between the seedlings, making them easier to remove.

    Not much. The water is completely contained in the reservoir, and can only escape by passing through the terracotta walls of the plant pockets. Depending on the weather and your seed-starting mix's absorbency, small amounts of water can seep through the mix and /or condense on the outside of the pot, causing damp "footprints." But no, water should never come out in any quantity.

    Your pot is likely broken. Please contact us right away and we can help you determine the cause. There is no charge to replace pots that have been broken in transit.
