If you're scouting now, remember we're only three weeks from the solstice, meaning the sun is still near its lowest point in the sky. Before you settle on a spot, take into account how much sun your plants will get during the growing and flowering season. Find some potential spots now, then go back out around the beginning of March. The path of the sun in the sky on March 1 will give you a good idea of what it will be like around the second week in October. The point is you want to avoid a grow area (if you can help it) that's only going to get two hours of direct sun when it's packing on the weight.
