Nice grow! You have a nice pile 'o' shrooms to start munching on there.
I like GT's myself as far as a favorite but they are all good. GT was the first strain I ever tried to grow and it grew flawlessly for me and was very potent. I personally like them better than B+. Another strain I have to come to fall in love with as of late is Ecuador. They seem to be a really visual mushroom for me.
