This is just a thought as I found your page by accident, sure I watched some of it, but was bored in the amount of implements you have just for weeding. It looks to me that you are almost a commercial farm and yet I don't see much deep litter / mulch between your rows. I have no idea how you started, but one thing I do Know is that less weeds should be the goal as the time you are taking to deal with them must be a pain in the ass. Since I am not, nor will ever be in your position I hope you look at other ways to do the same thing without your weeds. Good luck for your future..
