i guess it depends on how they measure it. disney has a tomato plant (or did, saw it on tv a few years back) that's in a hydro set up.
they have it going up a trellis system and extending out like grape vines for a really long way in all directions - i'd have to guess the thing was equal to at least 100 tomato plants.

and they don't say 1000 meters long or tall - just 1000 meters - so, if they trained it and measured each branch, who knows?

i do think they're being creative with their numbers - and i'm very curious about how they came up with that number.

or who knows? they're Spanish & those breeders don't always translate their material into English very well. could be an interesting typo & they really mean 100 meters - although that's still impressive.

i'm American by the way, so meters, kilometers, anything metric just doesn't compute for me.
