Good luck to you too. And about the spacing, they are actually spread farther apart than they look in the picture, The ground is uneven and sloped so it looks like they are close together, but thanks for the concernGrow looks nice. I have 4 growing outside myself this year. My first outdoor grow. Good luck with your grow.
P.s. I would move those two in the middle farther apart b4 they get much bigger to prevent complications down the road.
