what i mean by nuts is (nutrients) ie= plant food!! plants need different amounts of n.p.k for veg and flowering. (N)=nitrogen (P)Phosphours (K)Potassium. plants in the veg state use higer amounts of (N) and lower amounts of (P) and in the flowering stage uses less (N) and more (P) so two different feeds for both veg and flower work well!! i use organic BIOBIZZ Bio-Grow for veg and and tomato feed for flower.dont like using chemicals after all we dont want to be smoking these chemicals so i go the organic route better tasting buds by far.. these work well for me anyway and the results are good. ya 2700k warm works well for flower but no so good for veg i uses a mixed spectrum of bulbs 3x 2700k and 2x6400k thes work well for both veg and flower. WHAT a male get that mother fucker out of there straight away if it pollnates your female, the female will put its energy into producing seed not bud. destroy the male or else move it far far away from the female once the male sacks open it releases pollen into the air. just a small amount of pollen can ruin your whole crop. even if you have the male far from the female and the pollen from the male gets on your hands or clothes and then you touch the female it will still ruin your crop. get some picts up man they mean a thousand words>>>>
