I got the seeds from a seed bank advertised off here. So i bought the proper stuff. Its my 1st grow and am quite pleased with the result. From bottom of the pot to tip of plant, the tallest is 4 feet tall. Som i have taken the bottom leaves off some i have left so i see if theres a difference. So the plants will flower i havent got duds then and they wll die. Is it when the natural sunlight will be 12 12 that they should start flowering? If so I will probably harvest around christmas time!!!
