You can get bubble hash with less plant matter from fresh trim and popcorn buds, higher quality, in some cases fully dab-able…but you get much better yields overall (even accounting for additional plant material) with dry product.
You can still make full melt bubble hash easily with $10 worth of ice, 2 x clean 5 gallon buckets, a piece of cardboard, a wooden spoon, and a set of $30 Amazon bags. Made about 30-35g last night myself. You only need a 3-4 bag set.
