>>555945Yeah it's goofy thing. So far it's the biggest thing I've grown, and it just started.
>>555947I did that once with some Bush Sugar Baby watermelons. It worked ok, they were only about softball size but sweet. The variety is important for inside. Giant vines would be a pain.
Personally I would try it with some Minnesota Midget cantaloupe. Small productive vines, and the best is you can see/smell when they're ripe. It sucks to pick one of your two watermelons and it's not ripe or over ripe.
