This was my third year growing these. The first two I struck out, but this year I gave them extra nitrogen and they took off. I had great germination rates with indoor lights and some foil wrapped around the lights to keep in heat and humidity. The vines are big enough that they are threatening other plants in my raised beds and need to be cut back, and I get loads of fruit- I pick them by the handfuls. Make sure to feed them well and give them room. They'd probably be happier on a south-facing fence than on my trellis.
