Does my LED need more red spectrum for flowerin?I have an HLG 100v2 LED grow light at 4000K. They say 3000K is better for flowering. Does it make any sense for me to add some cheap red LED strips to add red spectrum? I’d rather not buy another more expensive light if I can just supplement this one. See picture.

Grow Light distanceDoes it matter what heights I have my grow light at as long as my pfd is where I want it? For example could I have it closer and less power or do I want it further with more power. Feel like it would be better for the light the less power being used.Week 4

Led on 18/6 grow/flower photoperiodI have the idea to put a led in my second tent for pre growing photoperiod girls, I have some room left over for some autoflowers who also grow & flower on 18/6 light - leds can switch between grow/flower.
If I switch the led to flower will that be OK for my photoperiod girls?Setup. Lighting

Trying to get setup rightI know I prob need to get a nicer light and ditch all the crap lights but for now I have what I have. Perhaps after some success I may be able to get a new light to replace all of them. But how far should it be? 2 feet above rockwool cube? And what watts per plantSetup. Lighting

Plants Growing Taller Than LightMy plants are growing taller than the LED light! The hanging wires that came w/ the light are now too long; even after rigging the wires so the light will hang at a higher distance. I am using a 4 ft. tall grow tent. How/what can I use to adjust the height of the light?Week 9
