So I feel like I should be yielding a lot more BHO than I am although I could be wrong.
I need some advice on how to maximize my yield.
Ive read conflicting opinions on almost everything I can find about BHO.
Is it better to use ground up plant material or keep it together?
Should I pack the extraction tube lightly or more tight?
How many canisters of butane should i put through a 40 gram glass extraction tube?
Is vector really the best butane to buy for the price?
Any answers are much appreciated.
Ive been getting 3-5 grams after running 4 canisters of butane through two separate 40g extraction tubes. 2 canisters per extraction tube.
first off you want to used very finely ground up material that is DRY (important) or if moist then frozen.
you want to pack the tube medium tight, vector is good but i use mega 7x runs clear on the mirror test and cheep $35 a case where i live.. (spay butane on a mirror or glass jar for 5 sec and see how much residue is left..if barely any than its good.)
the amount of butane needed depends on diameter of your extractor and the cronicness of the material you are using. rule of thumb would be to run the butane till it turns clear.. also was reading that a tube of 1" inner diamerter works best as all the trim comes in contact with the liquid..
I would recommend the dry ice method for best yield.. put your material in a bucket with dry ice and shake with a bubble bag over the top doenst matter which screen the most course one works best as it does not matter how much plant matter come through when you are going to be blasting.. collect the keif on a glass mat or simular surface by vigorously shaking the bucket/ bag till all the keif come out. i got 29 grams off of one case of butane (12 8oz cans 800ml) and 137 grams if dry ice keif..
ALSO COMMON SENSE DICTATES THAT YOU DO THIS OUTDOOR OR IN A WELL VENTILATED AREA...DONT BE STUPID AND BLOW YOURSELF UP....
Also here is some great info for you here (very indepth)

Happy hash making and hope you never have to such a low yield again...
