Anyone used the Phlizon Cree COB 2000w lights? I’m running two in a 8’x4’ under a scrog net. 5 weeks into veg but nowhere near where they should be. Used only the COBs in veg as some suggested but had to put on full blast today and hope for some speedy growth before I flower them

Should I flip?
I’ve got my plants in 2gal fabric pots and I’m not planning on transplanting up. The plants are averaging about 8/9” and I’m starting to see small roots out the bottom. Should I flip to flowering, or can I get away with another week of veg?

Mars Hyrdo TS600 - 100w but mistook for 600w
I've recently found out that the led light I have which is a Mars Hydro TS600 is not in fact 600w and is actually 100w. Do I need to compensate in any way? My plants look healthy but short, I don't want to put the light too far away that it's ineffective, how close is too close?

Is this stunted or normal?
This plant is 36 days old. Does it look behind or on track to you? I'm wondering if I stunted it or of I'm just over thinking it. I'd love to hear any feedback but especially want to know how you think the size is. Also light to weak? 54watt optic phantom

When did the flowering start?
The LED panel, after switching (Ts600 Mars Hydro), stayed slightly on even during the dark hours. I managed to fix the issue, but I'm not sure how to count the flowering period. The plant had shown some differentiation, a few pistils, and a bit of stretching. What do you think?

Different lights
Hello people, hope you all doing fine. So, I have 3 different light models, I´ve been using them individually for plants. I use only autos and adjust the light distance individually. Should I place all the lights in the roof togheter so all plants get the same amount of light?

Light Science
Has anyone watched some Youtube videos by Dr Bruce Bugbee from Apogee Instruments? I find his lectures on lighting to be the most straight forward explanations I have heard yet. I found his vid called "The New 400-750 nm ePAR Range Explained with Dr. Bruce Bugbee" to be eye opening on lighting colours. I have changed my LED's based on a few of his vids. He explains what plants really want and those Burple lights just don't cut it. For those that don't know he is a professor at the University of Utah that legally studies cannabis growth. He takes the science of weed grow to a whole new level.

Is 500 ppfd on new seedlings ok?
My light dimmer only lowers to 500 ppfd. I’m starting autoflower seedlings in a space tote before I move them into my perpetual harvest tent. I’m currently propping the light on its side so that the indirect light only hits around 300-400, as an attempt to reduce light bleaching.
