some tips, you dont have to use water in this at all.
Just melt the butter, then bring down to a simmer, add in the bud and let simmer for about an hour. Then use cheese cloth, or clean womens panty hose, and strain.
Note, you never want to get the Temp to high, the thc will start to cook off/out. soo baking brownies is a bad way to digest THC, since the temps in the oven are so high.
It is better to make Rice crispy treats, since the butter is added straight in, and not baked. the best is :1 part rice crispy and 1 part fruity pebbles !!! THIS IS A GREAT GANJA TREAT. and they are very potent.
p.s i have found that extracting thc into Oil , for some reason makes it waay more potient. Try making a white pasta, using Olive oil or Veg. oil, and extract the thc into the oil, i honestly was tripping from that
