Get some bubble bags off ebay. Even the cheapy 3 bag set works perfect. Then you need nothing but some ice and water.
I personally dont think there is a cleaner smoke than rosin from bubble. Being I have heart issues, my heart is affected every time I did dabs of BHO. No matter how hard you try or how great of equipment you have, you will never get true "clean" BHO. I dont think it can even be done in labs but I'm sure someone will correct me if I'm wrong.
Bubble hash is 100% natural, clean and chemical free. Rosin made from bubble hash is heavenly.
I get a 25% return on my bubble to rosin with a hair straightener and parchment paper pretty regularly.
My last batch was 2.3g of rosin from 8.2g of bubble.
