Funny you should ask - I just finsihed two. They both grew short with one main thick cola and several smaller branching colas. I wasn't impressed with the yields so much - about 3.4 oz for the two. I think the yield potential is there. I'll let my next grow with the clones veg to 24" or more before flowering because mine didn't stretch much and with the extra vegetation the yield could be large because the colas get fat and heavy.
The potency and quality of the product is up there. The effect is long lasting compared to many I've grown. I find the effect to be very pleasant. It puts me in a warm fuzzy mood in which all the events happening around me are pleasant. It's not speedy nor is it couchlock. It can be trippy if you take too much. I'm going to grow it again.
And it doesn't give off much of a pot smell when growing.
