Wow that is awesome you must grow a lot of veggies. Thank you for letting me know that I did not know that. I don't know much about gardening at all. Last summer I had a topsy turvy tomato plant and I was lucky if I got 7 tomatoes. If fact the only thing it was good for was when you walk by you wack you head because you have to hang it upside down. I said never again will I use that topsy turvy.
Your absolutely right. That topsy turvy should be put on the danger list due to all the people that whack there head on it. It has a lot of dirt plus water it is solid and hurts really bad when you walk into it.
