I think you can grow just about anything there. 10 hours of direct sunlight is very fine and i'm sure you can grow VERY decent bud there. I would start them early and prune them to get a nice and low plant with lots of buds on it. Just prune all the tops the whole summer if you want it low and handy - if you have the space to grow it big... do it ;O)
But - no problem to grow almost any plant on your veranda - it's plenty of direct sunlight. Get outdoor strains that will finish early if you live in a place with cold climate. Remember that expensive seeds often are way more potent than cheap knock offs.
Durban from Sensi Seeds is a great outdoor bushy sativa, but any outdoor plant will do good, so just browse around - use the banners on this forum to get to the seedbank, so the people running this great site will earn their commision ;O)
