I dont really know a way to increase the potency of the buds, but i do know how to extract all of the thc from the buds so you can experience the full effect of your shit.
You will need ONE CUP of food grade glycerin.
ONE OUNCE of top grade bud....chopped up with scissors or a burst in a cuisinart.
A Quart jar with a good SEAL.
Put the ingredients in the jar and give it a shake for about 5-10 minutes a day for two months. (IT IS WORTH the TIME!)
Press out the glycerin in a food food press(or good strainer); and put in brown bottles with eyedropper.
I use a professional food press, so I get back the total amount of glycerin plus a little extra. A ricer will also work well if you line it with cheesecloth.
for me, this shit is killer.. I did three drops first time, and I had a hard time moving from the spot that I was in, 3 hours later, it lifted a tad bit but shit its like smoking a blunt of some widow its crazy.
