How much more work do I need to do befor I can plant I'm starting with clones. Will prob plant in the ground next weekend. 1st box is what I believe done and working on second box. Do I need to clean all the weeds out side my boxes out to or are they okay I still will be weed whacking them down but don't wanna pull all of them. And how many plants do you think I can fit in each box. They are 12x6 each and will have corn on the edge all the way around.
