Hi I'm relatively new growing aroids. I've already propergated colocasia esculenta, got the bulbs from a grocery store. But recently I've ordered Thailand giant. I no the basics ( watering, light, fertilisation ect) but the problem arises when overwintering the thai giant. I no that it can't be stored as a bulb, and that you cut of all the leaves to leave the stem and pott it. Its just where. I have a large south facing window space...will that do or do I need grow lights? Thanks Harvey
