hi, where would you buy good potting soil for growing vegies in ko phangan? what type of soil works best for peppers and misc vegies? thanks

A gartner shop (nursery) selling plants and trees will often have bags with soil, and can advise you the best one to use.

if anyone interested, there is a great place on the chaluklam road about 1km from tongsala, opposite the amphur, 5 bags for 100 baht and feels good quality dark rich soil, not that wispy coconut coir stuff
