Forget all this complicated shit ye.. because this is your first grow ye all you need is biobizz grow and biobizz bloom and they claim ther organic too, so that biogrow and biobloom and thats about £10 each, or get any which say grow and bloom for example hesi grow and hesi bloom and like texas grass sez biocanna but you only need bio grow for the vegatative stage and bio bloom for the flowering stage...
