Last year I visited my boy in june, who moved to nor.cal. to grow legally. He had a 15ft long plant LST'd to fuck, it was literally tied so tightly to the ground it grew surface roots that eventually helped hold itself to the ground along with several feet of 1/4" rope and tent stakes. By the end of the season it still produced close to 2 lbs.
I personally an a regular gardener so my neighbors see me out messing around everyday in the garden. I grow tomatoes, peppers, beans(vine growing only), and once grew corn. I highly suggest expanding your interest in growing marijuana to the rest of the horticultural world. I grow illegally but have never had any problem from my neighbors, mostly cuz I believe in karma. I'm a genuine nice guy, I smile and talk with my neighbors, always making fresh organically grown salsa straight from my garden and sharing the wealth. I'm sure they can smell it being smoked in my house everyday, but I don't cause any grief to anyone so they leave me be.
I highly suggest any tomato/bean plant you want using a net or trellis to grow up and block sight, or Helianthus Annuus-Russian Mammonth Sunflowers(specifically) they grow friggin tall and aggressively fast. Depending where you're growing your climate will vary results. I no expert but I've been a general gardener a lot longer than I've been "growing".
Other than anything already covered I once did a gorilla grow next to a creek bed and propped up a cheap tent(with a zipper top w/mesh to let in light and good air flow) I got at a yard sale, directly over 5ft deep by 4ft wide hole and plopped a plant I had nurtured for about 3 weeks. I left it to mother nature and my good karma to keep it safe. Got 10.6 oz from it after 3-4 months, tracked it back using my gps..................Hope this helps, sorry to carry on, I'm way blazed right now off my latest Kryptonite indoor grow lol
