How to grow Coral Red Radish Microgreen Seeds
To get started, weigh the correct amount of Coral Red Radish seeds based on the size of tray you’re using.
Fill a tray evenly with your chosen growing medium, such as compost or coir. Gently firm the soil or coir in the tray and water it. Spread the seeds evenly across the tray, then cover the radish seeds with another tray. This helps the roots push down into the soil or coir.
Place the tray in a warm location where the temperature is between 18-21°C.
|Tray||Size (cm)||Sow Rate|
|Modiform ecoExpert punnets||13.6 x 10.3||4g|
|Garland Small Seed Tray||23 x 17||11g|
|Garland Seed Tray||37.5 x 23||27g|
|Garland Microgreen Tray||56 x 28||48g|
Sow rates are provided as guidance only, sow rates depend on environment and seed quality.
Once the radish shoots begin to push the tray up with weight, flip tray over and put it back on top of the other tray. This allows for more space for growth while maintaining the blackout period.
Once the radish seeds have fully germinated and reached the top of the tray, it’s time to move them to under lights or a sunny spot where the temperature and humidity remain consistent.
Radish microgreens are usually grown densely to maximize yield per tray. However, growing at this density can promote the growth of mould. To reduce the risk of mould, it’s best to bottom-water the plants. Add a small amount of water to the reservoir tray (the tray with no holes) and allow the radish shoots and compost to absorb the water. Any excess water that is not absorbed should be emptied from the reservoir tray to prevent the radish microgreens from becoming waterlogged, which can lead to root rot and mould.
Once your radish microgreens have reached the desired height, you can harvest them using scissors or a sharp knife.
