bubble bag hash

I bought a 1 gallon 4 piece bubble bag kit and a 5 litre bin and I want to make hash out of a dry frozen oz of bud but is an oz enough

Yes an oz is plenty. Make sure to break the buds OVER the water so whatever trichomes fall, they land in the water to collect later.

I suggest checking out videos of @Frenchy Cannoli & Bubbleman on YouTube for proper procedure (mixing, collecting, drying, etc). Enjoy!
