Outdoor grow spots?

I need to find a creative place to grow in my backyard will no one can see. Its about 1/4 acre. Any ideas?

i saw a guy who built what looked like a fort for his kids to play in.
kinda like a tree fort but no tree and it had decorated banners the went up to a open roof so you couldnt see into and it even had a slide from it and a ladder to climb up..
turns it it was all plants in buckets that he watered everyday lol i loved it.


or put a decorative peice that would cover up the goods

Thanks those are both awesome ideas. Any ideas for decorations?
