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

Grow lamp setting veg or bloom or both?
For my grow lamp settings this early on should I be using the VEG And Bloom spectrums simultaneously? Or just leave in Veg? Since these are Autos I wasn't sure if switching the spectrums was as important as maximizing light.

Too much light ?
So started my second run and got everything dialed in but this time I’m running with spf-1000D and the normal spf-1000 is that too much light for the plants that would slow them down ? Together the lights should be around 200w

Know any sponsors for influencer growers?
Does anyone know of any companies that sponsor led lights or a company that sponsors nutrients? I also have a you tube channel I grow cannabis on and do reviews.

Is closer to the light much better?
Is the light closer better? I have a VIPARSPECTRA 1000W LED Grow Light (10W LED ,x100) and it says during veg 18-26 and flowering distance at 18-24”. Looking at other growers using LED they are closer. Should I try to keep it closer a little at a time? Is there benefit?

Lights for heat- 24/7 okay?
I really need the heat of the lights to keep the inside of my tent warm. To warm the air around the tent 24/7 would be expensive- much more expensive than using the lights all the time. But will this work with 24 hour lights? Will that stress the plants? Using auto flowers.

Started the plants off with 60 watts. Increased to 100 watts today with a 20/5 schedule. Could I increase to the full 150 watts already or should I give them a few days with 100? Thanks in advance for any advice. It’s my first indoor grow with this setup and I’m still learning :)
