Another excellent option for carrying your stash would be to convert it into edibles. Not the typical pot brownies either.
Make tinctures and keep it in old herbal extract bottles, like valerian root, make an oreo no bake cheese cake with weed/hash in both the crust and the filling, make some green dragon, and disguise it as mamahuana with a big piece of sugar cane in it. Go cannabrex style and make some kief/olive oil/cayenne pepper caps and put it in a st. johns wort bottle, etc. etc.
When it comes to edibles the possibilities are endless. Not only does that help in and of itself but do some research on Watermelon's case up in B.C. She got busted for selling pot cookies, but fought the case and won when the lab couldnt prove their were cannabinoids in the cookies. Now, whether she was ripping people off or if cooking changes the molecule to a form normal tests dont notice, I dont know, but its an interesting fact to ponder nonetheless.
As far as the grow equipment, keep a bunch of specialty seeds like miracle fruit, goji berry, maybe even some cactus species, and front like you are a small scale exotic nursery supplier (or seed supplier of heirloom varieties) if the issue arises. Its not paraphernalia if its being used for something legitimate.

pretty simple bro, i know your gonna be trippin balls when you drive with that shit, but make sure your following the rules of the road (cruise controll comes in handy lol)... but straight up, if your driving proper, you should be golden.. good luck
Cops don't carry very good SAMs, they do keep a few in trunks but not ever department. It really depends in what sort of circus your traveling around in.
Usually they do know that someone is coming, friend or foe. I never found a clear distinction but some is more nice than others.
