Brownies, suggestions welcome

Hey everyone, I'll be making a batch of brownies tomorrow. I'm going to be using a quarter of some nice bud. I'm not too sure on how much butter I should use, for a quarter is it safe for me to use 1 1/2 sticks of butter or should I use 2 or just 1? I'm going grind up the bud very finely until it is like sand. I will then add in water to a pot, heat it up a bit and then put the butter in and allow it to melt. I'm planning on putting the bud in there for at least 2 hours so they come out as a nice batch. Now the only thing at the end I'm confused about is the final procedure. Just strain the mix through a strainer and then pop it in the freezer, let the water and butter separate, once frozen remove the water and add the butter to the brownie mix?

Any and all Help is appreciated

title should actually say, Help Please

Use 1 1/2 sticks. Put water and and weed and butter in pan. Let it simmer for 1/2 hour.
Strain out the weed with a fine mesh of some sort. (panty hose) Run hot water throgh the strainer to get last bit of butter out. Put in the frig/freezer. The butter will seperate and float to the top and become a solid again. Use butter as ya like.
