The Height growth nearly stopped. I start thinking, that I might have given her one or two more weeks of vegetative phase, just so it starts filling the whole box at the end.
But let's see what the outcome will be.
Also it slowly starts smelling a bit also with the box fully closed. Will try to make the best out of it and check if I can reduce the smell a bit more again.
@Zarayju, Sorry for the late answer, I was not checking here frequently.
I've bought those from Lientec-LED. They also offer a lot of DIY-Sets. Keep in mind to also order some aluminum profiles, as the heat of the LEDs needs to be dissipated.
