crock pot/slow cooker

how much motha fucking budder am i gonna get from an eighth or a quad? i need to know so my friends and i dont waste our money making budder if we would rather smoke the herbs as is

Making BHO with any less than a half ounce is a pretty big waste IMO. I even consider buying good weed with the intention of making BHO a waste. Butane extractions are for making otherwise unsmokeable plant material into a premium quality product. If you extract just an eighth you will only be getting a small fraction of a gram in oil. Isomerising the already small quantity of oil you would be getting in order to make budder is an even bigger waste. BUT if you have the money, time, and weed to toss around go for it.
