Buds fattened up in their 9th week of flower for me but there may have been a light leak toward the beginning of flower. One of them hermied a little but I managed to keep it under control until harvest. This may have affected the overall size unfortunately in the end.
My lady LOVED this light. First time grow coming from blurple, damn... The light penatration was pretty solid. My bushy soil grown didn't grow anywhere close to the hydro did under this light (4x size)
Great Light at about 12-16in. Saw flower bulking where closest within a week of adding. 4star because its connection points make it hard to angle and there's no power button. You have to unplug or use timer.
