Black Jack Auto Feminised Seeds
Awsome! These plants have the highest output Ive ever had. Takes about 70 days or so till they readyy to hang and dry, They are 4-6 ft tall and big and stout. When dried I got 3 -5 oz. per plant indoors. One plant gave me 6.75 oz! Dried! The buzz is awsome and long lasting. Jack H. new what the hell he was doing on this stuff.

I got three seeds plus one free thanks to a promotion. Germinated all four successfully in 24 hours. Planted with love and care and I've been happy with the results. I'm a non expert grower, this was my second crop ever so I'm learning as I go. Good strong plants, thick stem, two of the four grew to max height. Two were cropped and dried on week 10 and two are not quite ready. Cloudy trichomes, smooth yet herby flavour, cerebral (light headed) type of high. Happy overall.
