Many years ago I tried an attic grow. It was hard because of the heat and it was hard to get up to. I've sampled buds that are in the way of my path and they broke... duh! Whatever you do, don't cut the end of the bud off as that will stunt the growth of the bud and force it to get fatter...
With the temps as a general rule for most strains a constant 75 degrees F. is ususally the best..... I'm sure there are many that like other temp. One of the keys is "constant" try to keep it the same so as not to shock it. Good luck...
