I picked up some green 4' stakes and green ribbon today. One guy at the shop told me no problem driving the stake next to the stalk, the other told me to drive equal to the outside of the canopy and angle it in. I thought about my last indoor micro grow. I regularly inserted a moisture meter probe right near the stalk, all the way to the bottom of the pot, without any problems. I think when I go out to the site next I'll drop the stakes 2-3" from the stalk and just hope I don't hit the main root. Stealth is paramount so strings, fencing and obvious stakes are out. A passerby that know what ganj looks like will key right in on the garden but someone who doesn't is the one I'm trying to avoid calling attention to.
