Yo man.. you wont get nearly that amount off male plants... in the gumby video he is using 2pounds of bud trimmings from ak47.. those trimming would prolly get you piffed as all hell.. basically what you are doing using gumby method is getting the leaves sooo cold and stirring them up.. the crystal seperates from the leaves.. so inless those leaves are caked up with crystal.. expect minimum return.. i used about 3pounds of shake..and i got 1/2oz of bubble hash.. and it wasnt amazing when compared to the black stuff you see in the gumby video....
