fwiw, in south central PA and earlier in northwest Phila burbs, I had zip comma zero success with the updside-down-theory/plants/kits. sounded like a neat idea, didn't work out in the end. and I'm an avid gardener - as in hundreds of sq ft in veggies. as in "root crops" I love.... as in "had a 18x24 hobby greenhouse.... and paid to heat it . . .
tomatoes need full sun; so far as I can guessimate - the exposed pot/basket/container basically overheats and cooks the roots. I've raised tom. seedlings from seed - some put in the ground, actually in less than "full sun" but that's more hair of a shaggy dog story - same batch of seedlings in a 3 gallon 'upside down" arrangement. results were pretty much "ground plants were late (sun thing)" upside down plants.... well, they made good compost, but that's about it.
up at 5:00 am, peruse/tend the greenhouse, water the garden, water the hanging garden, still no worked for me.
