Very true, I guess I take for granted that everyones tolerance isnt as high as mine. I have not found any strain that gets me so high I wouldnt grow it again. Even if it is super potent, you can always just take 1 hit, but I suppose for some even that may be too much with some strains.
If you want to grow something just for your wife that has low potency, my recommendation would be the original Low Ryder Autoflowering strain. You harvest 55-70 days from seed and the low potency was the main reason LR2 had such success because LR1 is significantly lower. The best thing about autos is no worrying about light schedules. You can have 1 or 2 growing with your moms or clones under 18-24 hours of light from seed to harvest. They stay very short and might be just what the doctor ordered in your case. But man if she doesnt want to smoke pot, then so be it. If she does want to smoke but gets "too high", then she needs to start smoking more, it would be a much better alternative health wise than continuing to smoke cigs.
And sorry if I came off like an ass MrBlanco, I wasnt trying to single anyone out or anything. After reading what I wrote I can see how it sounds. Like I said, I just forget about some people's low tolerance to weed.
