I wandered onto this page about how to plant bulbs indoors. It mentioned that we need to place the bulb in the soil and put it in a cool, dark place for the root system to develop, which takes about 6 weeks. This is different from what we do here. I don't know what temperature range they're referring to when they say "cool".
Here in Hong Kong the weather is quite warm even in Winter (15+ degree Celsius , so what we do is place the bulb without soil in the fridge for 6 weeks. After that, we put them in the soil and let them grow. Are both ways correct? How do you define "cool"?
