hello rhino mate
outdoor drying is quite difficult for many reasons, firstly the climate, if its hot then your stash is gonna dry to fast, a lot of the thc is gonna convert to cbd and it will prob taste somewhat green or worse, secondly the light mate thats not good, and most importently those little bugs are gonna have a ball, from past experiances i never wanna dry outside,
having said that india and pakistan and even afghanistan outdoor drying is just about all thats done and they achieve fantastic weed,
i am sure there are some guys here that will have a answer for you, all i can say is when i done it, it turned out a complete nightmare for me, i had bugs by the millions mould everywhere, and what was salvaged was not worth smoking, i now grow and dry indoors, best of luck and peace to you,
