Making bubblehash is a process of extracting THC from cannabis plants using ice water and agitation. To get started, you'll need a few key products. First, you'll need a large amount of high-quality, dried and cured cannabis buds. Next, you'll need several large mesh bags, with decreasing micron sizes, to filter out the trichomes. Additionally, you'll need a large container, such as a plastic drum, to hold the ice water and cannabis. Finally, you'll need an agitator, such as a paint mixer, to help separate the trichomes from the plant material. These products are essential to make bubblehash, it's a simple but effective method that results in a high-quality product with high THC content and minimal plant matter.
