Inducing flower is completely up to you and your goals. Given the space you have her in your gonna get real crowded in there. That plant is going to double to triple in height and you don't have a lot of space in that trellis to weave them very far. Go for it. Weave them for the first week, then allow the tops to stretch up. at day 21 do your last defoliation to open the lower plant up to more light, and away you go!
