The mornings can be pretty chilly wat inland, i was surprisedThe Thai weed I grew comes from a betta farm (Betta fighting is a popular hobby in Thailand, Laos, Cambodia, Vietnam) from Sakon Nakhon;chatting with the person who gave them to me I remember him telling me that the owner of the farm lost a lot of fish a couple of years ago due to a sudden drop in temperatures...
I always wondered how low they could go to kill the fish...
It made the old Thai shower, which some may know about, quite challenging, especially with that barrel of water being outside in the cold all night..
I guess in the old days the plants were out in that too, I bet the nice warm days and cold nights push the plants to finish and may boost the resin a tad even
Here's a morning shot after the freezing cold shower in the rural parts of udonthani..
