I know I am late to this thread. My 2 centavos since all I use is hashish.
I have made in with bubble bags and from dry sieve as well. I have used dry ice using both methods. BTW, I think it works the best.
Bubble bags do give you more end product.
I have used dried product and freshly harvested using both methods.
I like and only use freshly harvested bud now for both dry sieve and bubble bags. I feel that the wet weed is less prone to macerating during the process so I get less micro leaf pieces in the final product.
If I use bubble bags I stir up the ice, water and bud in a 5 gal bucket then pour that into the first strainer bag of 220 microns lined in another 5 gal bucket along with other micron backs lined in it as well. . I used to agitate the ice,water, and bud in the 220 bag, along with the other micron bags in the same bucket, but found I had to buy another 220 bag in a couple years bc the process was too hard on the inside of the bag. I use a drill with a paint mixing extension on it. Use plastic paddled mixer not a metal bladed one.
I do not do 2nd or 3rd passes bc I dont want leaf material in my hashish.
Also, the end product can have a slight green tint to it. Place in the sun or under your led light for several hours and the chlorophyll will oxidize into a light golden color.
Dont forget to press you product after drying into a brick or puck so it can be stored in the freezer if needed.
Hope this helps. Sorry if I repeated info already posted.
