Mmj Grow On Roof???

hello riu, i want to grow outdoors. the only problem is that my backyArd gets little sun, I live in a big house and its taller than my niegbors, would it be a good idea to grow on the roof with plantz fastened down?

I was playing dying light (zombie game), and some survivors started a garden on the roof, since food was scarce. It looked like an awesome idea until a few jets flew overhead.

police in my area use helicopters often and would be impossible to do for me. I guess it's up to your circumstances. U legal?

It would also depend on how tall you going to grow. A tree growing on your roof maybe an interesting sight, just like a flag. IMO
good luck
