Canatonic where to find?

I just saw a youtube video of juicing raw canabis leaves for extreme health. I heard about Canatonic and was wondering where do I get that strain? And is it really the best out there in regarding its description in the video?

Thanks that helps really. Also does anyone have any experience growing this type? And does anyone know where else you can buy it so I can compare prices? Either way thank you.

Oh and just wondering. Does anyone know how to tell if a seed is feminized or male just by looking at it?
