Ken, I have got no idea if KL is really hotter or Singapore. But it feels hotter when I was in KL. 'Cos S'pore is so small so air ventilation is pretty. In fact, the void decks of the government housing are always very breezy. Most of the time more breezy than the units above the ground. Probably the land breeze.

I'll take photos of the different forms of sphagnum moss I have and post them up.
