After many runs, and getting my setup dialed in for me, I run 220-160-90-45-25
And only smoke the 90 & 45 and run the 160 & 25 in edibles. Just like growing, everyone has a way that suits them. The one thing that I do, is right after scraping the screen off, dunk it in Isopropyl Alcohol, swish it around, then rinse with cold water, and hang to dry. This way, I have clean screens for every wash, and don't have to worry about them gunking up and clogging, ask me how I know, LOL
There is a difference in grades, and you have to find what suits you, my 45 is a very nice "sativa" type high, very cerebral, and my 90 is more "couch lock"
As much as I like flower, I enjoy my hash much better, and next years outdoor run will be strictly for hash, the wife enjoys the hash much Better also, and it's nice keeping her happy!!!!!!!!!!!,
