I left my plants in Veg state for 2 months (cause I didn't know any better) -- they were about 3 feet tall or taller when I finally cut them over to 12/12. They ended up being around 4-6 feet. The smaller plant yielded about 2 oz, while the large plant looks like about a 114 grams (QP).

The pics are of the larger of the 2 plants. The drying stuff is all the big plant in the first picture
