Stopped to check on the other 7 OG seedlings (the ones I hadn't dropped off at the plot) and they were gone.
This area wasn't too far from where I live (made care easier) but I always had a feeling one day someone would find them. They weren't hidden as well as they are at the plot. But hey, I have all the seedlings I need and a few extra at the plot, and have the one I found in the birdseed pile potted up in a different location. This is just part of the game.
Since I'm tight on time and the plants are already in the field, I'll just have to wait until they're full grow until I sex them. I'm also considering doing a plant or two in the swamp I mentioned earlier. Couldn't make it out yesterday because it was storming (no surprise) so hopefully today will be the day I get the plot settled.
