The size of your trichomes usually corresponds to harvest time. Most trichs are between 50 and 100 microns which means your 45 & 74 bags will usually be the most potent but a 90 bag can also be very good depending upon your harvest times. I tend to harvest on the early side so my trichs are usually small. Having a lot of 90 trichs shows you likely waited till full maturity or later to pull buds. I'm not one to critique your shit but it looks a bit green to me meaning you picked up some chlorophyll in your hash which is a common bubble hash issue...next time try to be even more gentle & let the cold do most of the work. Get yourself a spray bottle & spray the hell out of each bag with very cold water onto the trichs collected from each bag to try & push through some of that green back into the water. You are better off doing more washes with less agitation than grinding your material to a green pulp. Use the 25 shit to make hash butter & enjoy smoking the rest!
I like to press out as much water as possible on a screen with paper towels underneath & combine my washes into separate grades. I then chop it all up into sand with a razor on glass Pyrex to dry for an hour or so. Then I push it into a pyramid shape....why? Because it makes it easy to cure that way in a little jar but it never lasts very long. I've been making a lot of shit into oil these days but I do miss doing bong loads with a fat chunk of tasty hash on top. (Sigh) five more weeks...
