To save time and cost in heating the greenhouse, it is recommended to pre-sprout the bulbs at 25-30°C in a dry and well-ventilated room for about 7 to 14 days, depending on the variety. As soon as you can see the tip of the buds, the bulbs are ready to be planted. Plant the bulbs in a pot with a soft and wet substrate and keep the root zone at around 20°C. Do not over water.
