What's up flower power? Welcome. I personally don't know if the afghan kush ryder is one of the smellier strains. But as far as 5 yr olds go, he/she wouldn't know what they were smelling if they did smell it. Would they? Or are you worried about the smell having adverse effects on him/her? I remember reading somewhere that the smell alone won't have any effect on you, unless you are allergic to the terpenes and what not.
