Hello guys I want to share with you my butane hash oil extraction
Some people can say, its dangerous, but thats actually not much true, if you dont use fire or heat, to separate the excess gas
More safe way to do it is vacuum pump, but its expensive to buy
So the most cheap and smart way is to go to the Household waste recycling sites or how to call it in English and remove compressor from some old fridge or freezer ( u usually paid just for material so it cost me about 5 dollars ) sometimes its for free
on these compressors there are 2 coming-outs for hoses, 1 is suction and second exhaust, so you just get some jar and put some air valve to the top so you can exhaust air from the jar, boom you have vacuum pump for about 10 dollars ( if you want, you can buy manometer for have it like a pro but I dont use it )
You can see how the BHO is working and inflated when you exhausting the air from jar
From that 236 grams it was about 20 grams of bho ( it was trim from buds and small buds )
I dont have photos of my fridge vacuum pump, so this is from the web for better idea ( I will do it next time )
