them plants are getting big mate, last season did you grow out doors also, if so when did they finish flowering by, have you ever thought about getting a plant to flower in the middle of summer instead of waiting till the natural light is right for flower, i have been reading that if you grow a plant in a pot out doors but move it in to force it to flower, this then produces bigger buds as the sun is at its strongest in the middle of summer, when i read this i thought about the blue and red light needed to flower, so if the red light was needed to flower then that would mean plants flowered in the middle of summer would not do as well, but clearly they do, have you ever tried this mate and had them flower early by taking the plants in for the dark period
