You can pre-cultivate your seeds 8-10 weeks before re-planting outdoors. Besides keeping the soil moist, it is important to provide your cultivation with additional lighting during the darker months of the year. To keep the soil moist you can cover it with plastic or use a mini greenhouse, where the temperature should be around +18-21°C. Once the seeds start to germinate, it is time to move the cultivation to a brighter and cooler area. When the plants have grown big enough to be handled, each plant can be transplanted to a pot of fertilised soil. Transplant your plants gradually and replant them outdoors when the night temperature is +8°C at the lowest.
