By the way: Have you noticed how early it is to start flowering, being the "sativon" that it is: It was born the 1st week of May; it showed the first female pre-flowers a month and a half later, in mid-June; and a month later, in mid-July, it clearly started to flower (with the solar photoperiod of 38° North latitude!). Other "sativones" of this type do not start flowering until September, here...
