Cheers. I am also using P600. Question regarding light duration: do you start off with 18 hours or just 10 or 12 for seedlings at the beginning?

@Freddd, No auto flowering... You have some beautiful plants there.

@Freddd, thank you for your reply! I will keep that in mind. 1. Right now I am still experimenting and learning with this new lamp (it's my second LED; brighter but same wattage). Apparently I was keeping the lamp too low which I learned from my first lamp, which was not full spectrum, pink light, sorry for my amateurish technical descriptions... So working with the new lamp lead to few branches and narrow-squat leaves - kinda just lying on top of each other with little space in between. I will try to maximize space to the plant after making sure the seedling does not tip over providing a closer distance at first. 2. Also would be interested to know: when do you induce flowering? Depending on age or size?

Cheers. I am also using Viparspectra P600 as my only lamp. Having trouble with vertical plant growth after seedling phase. How do you do it? Would you rather reduce brightness to I don't know 80 % so to get some length? My tent is only 180 cm in height so won't be able to hang the LED as high up.
