I went with HLG based on recommendations here and I never learned much more about lights. So I’m not the best to advise
You have all ur exhaust system for ur tent and ur fans for moving air in ur tent i cant think of lights at the moment
I have the complete 4x4 marshydro complete tent kit and 2 oscillation fans humidifier and that’s all @Aussie_autos
Definitely look into HLG Lights. They are the best by far!

She’s a little behind, but that happens. I’ve got a Zkittlez see right now taking her sweet time.
What are the rest of your environmental parameters?
90s high, I’d try to keep below 85 for sure. She’s probably just taking her sweet time dropping some roots. They’ll often appear to stall in larger pots while setting roots.

I’m watching a video now that says the sweet spot is 41-51 @poly @Fiz @Underthestairs @Retiredoldguy @Aussie_autos
No for seedlings you want to be 15-20
There’s an edited version around. I’ll see if I can find it.

Most people around here make the same adjustment that bridges the gap from between to two highest lighting outputs so you don’t dim then until later in flower.
