is there any reason why growbags can't be opened at the end, rather than in the middle - you could then prop them upright? Perhaps that way they'd fit - you may get less plants in the hole, but they'd have a great root run.
I'm just thinking, for newcomers to A4A to find pictures of tomatoes growing in upended growbags under the heading "French Beans" could have severe psychological effects ;)Phil
