Make sure you look at all of the nodes on your plant - I made the mistake of just looking at the top few nodes and saw a bunch of pistils, loving life. Luckily, one of my friends came over and was checking it out and took a look at some of the nodes closer to the bottom of the plant and there were a bunch of nuts - I had a hermaphrodite. Obviously, we separated it, but had he not come over, I may have pollenated my whole batch!!
