seems as if you did well. but id still say grind that stuff up i'd bet your yield would improve as least about a gram. i used only stems from some ditch weed. ground it up to the fine powder like i was talking about. yielded was very golden, and not dark at all. it was honey oil. very honey like in resemblance, and smoked wonderful. so if your using better material than DTB(down town brown) and you probably are if you using actual nugz. you cant get a dark color from BHO if your material is quality, same as making any kind of hash for that matter.
just curious how many oz of butane did you use? and how much plant material?
I know that it wont make "black" oil, but it will not be as golden as the stuff i made just from bud. (i like the really golden shatter, not so much the darker golden stuff, ill include pics)
i was thinking on spraying all of the popcorn buds, letting them dry out, and griding them up and doing a second rinse.
As for the amount i used, i sparyed a total of 22grams of really light, fluffy popcorny buds(all dry) and used 1,1/2 cans of butane, yielded 2.9g
Anyway im including pictures, the first one is of the shake i am using from my harvest, and the third one is of the first run of BHO i made out of this stuff.
