What is the proper way to dry and not get the hay ...

Heloo @11Hick11 ! What you need to do is a slow drying process but not to slow because you risking bud rot development . The best conditions to do that is at 18 - 20 °C and around 50% - 55% RH. If you don't have the equipment to achieve stable environment conditions you need to adapt. For example if you have a hot environment with low RH you need to harvest at about 4-5 hours after watering so the plants have water inside them and won't dehydrate very quickly . If you have a cold environment with high RH you need to harvest 1-2 days after your last watering so the plants don't have a lot of water inside them and not having the risk of bud rot development. The best period of drying at optimum conditions is around 7-10 days or until the little stems of bud sides brake when you pull them instead of just bend . After that the best way and economically affordable to cure them is inside a jar at 16 - 18 °C with a Boveda envelope. I like the Boveda with 58 RH. Most people like the 62% but that's on your personal preference. I can guaranty you will not loose any terpenes with boveda.
