Plant development was still very fast growing, very strong beautiful leafs. Very nice finger shape and absolutely no issues @ all. At the end of week 5, I raised up my Sanlight Power from mornings to midday maximum 75 % so that means exactly 750 µmol m-2 s-1 with SanLights. And I started to push them too by using more CO 2 up to 650 - 750 ppm.
