I am a chilli grower in Ratchaburi (Amphur Muang) had some good success growing everything from the jalapeno to the calorina reaper (worlds hottest) plants grew well but insect are a problem here spider mites and chilli maggot
started at home to see it was viable to grow these varieties here worked well so will be starting a 1/2 rai garden in school holidays for chilli and other fruit and veg aquired lots of varieties not available in Thailand so will be an interesting year ahead seeing what grows here
