The light is to far away. You have a dimmer so you can put the light closer and run it with less power.

Light spectrum during veg and bloom periods
I have 2 1000w full spectrum lights. Each light has 2 switches-a veg button and a bloom button. This gives 3 settings for the lights-veg only, bloom only and both lights on at the same time. What settings should I use during Veg and during flower and how close should I hang them?

Led on 18/6 grow/flower photoperiod
I 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?

Can you use a 450 watt white led light to start seedlings? If so what distance should the light be and when should I make it closer? The reason I am asking this is because I don’t like transplanting autos as they are fragile to transplanting from what I’ve looked up

Are these stretching? What should I do for the 2x top that barely sprouted?
Viparspectra xs2000. Just moved it to a 25" distance and 50% light intensity hoping it'll help, but unsure if it'll burn them? What should I do? Top 2x seeds JUST sprouted and are just barely above the soil. How to accommodate all plants regarding light intensity and distance?

Kingbrite 240W
Anyone else using Kingbrite 240W lights? I’m running 2 in a 4x4 tent. About 30” from canopy dimmed way down. Just shut 1 off, feels like too much light in early veg. Curious on the lighting distance and intensity during veg and flower

Led mounted on side wall instead of top
So I'm thinking about to build a pc grow box, just for seedlings. When they start to be bigger I'll move them to bigger grow box. I have a spare grow light but it's to wide to mount in top of grow box. So I was wondering if I could mount it on the side wall?

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.
