There's lots of good info on triploid/trifoliar plants over at icmag. Long read though.

dillhole Reviewed by dillhole on . triploid cannabis Any experience here with triploid cannabis specimens? I grew one years ago and the mass was excellent but the potency could not be compared as it was the only specimen in the grow. Two years abo I had a 6 gal bucket plant with a triploid doing very well when I killed it with deseased nutes. I started a germ last Sat. and I have one triploid. It's a little crooked, but I think I it's good. I just wanted to know about the growing and smoking features of this genetic anomaly. Shov Rating: 5
