Congrats on the full melt, @BackcountryBlazer.
You say you were disappointed in the quantity. One thing that seems to get glossed over in a lot of ice hash discussions, which seems critical to me, is the ratio of bud to leaf, and the ratio of bud/leaf material to ice/water. Can you elaborate in your circumstance? And I'd love to hear from the group on their favorite ratios.
For me, I'm typically working with trimmed leaf (everything from shade leaves to sugar trim) and "larf" - the immature buds smaller than say 10mm/half inch diameter. Typically, I'm using Bubble Bags and two 5-gallon buckets. The first bucket is 2/3 filled with ice, then about 4-6 quarts by volume of leaf/bud material, then filled with cold water. I agitate for 15 minutes, pour everything into a second 5-gal bucket with the stacked bags, let sit 15 minutes, and start pulling out the bags, one at a time. End result, depending on strain and bud/leaf ratio, can be from 4 to 8 grams approximately.
