Start at 36"inches and work your way to 18" as the plant grows.

Viparspectra p1500 flower?
Anyone use a viparspectra p1500 during flowering? Got this as a cheap intro led and I feel like the plants stay in cottonball phase of flower...brought one outside and now its loaded with buds. Idk if this one has slow genetics or if the light isnt delivering correct spectrum

New Light? Find a way to raise light? More Fans? Combination? (Light: 44" above ground level | Tent Height: 63" Day avg: 78.6f) Should i worry?
What do you guys recommend as far as lighting for this tent? I have a 300w led light but at the height it's currently at it is producing a large amount of heat with my exhaust and two oscillating fans? I also have other plants in with my seedling so could the humidity cause it?

Veg or Bloom mode for Autoflower?
Hiya Folks 😊 As I'm growing an autoflower should I be using the bloom setting on my LED light instead of veg setting? It's only a 200w system and I'm growing in a 3'x3'x6' tent. My plant has just done 28 days from seed!! Cheers 😉

Light schedule
So I got a new timer and messed up schedule. Plants got 16 hrs of light, turned lights out as soon as I noticed (5am). 11am-11pm light.(5 weeks into flower) Should I let plants have 12hrs dark now and resume 12-12 , or let lights come on at 11am(6hrs dark)

Lighting schedule?
Many references state the when moving from vegetative to flowering stage the lighting schedule (indoors) needs to be reduced from 18-20 hours down to no more than 12. Why do many here stay at 18 or more the whole way through?

Lighting Horsepower
I have a Horticultural Lighting Group 260 QB V2 R Spec light (260 watt LED). I previously had a 20" x 36" tent and the light was great. I have just gotten a 36" (91cm) x 36" (91cm) tent and wondering if this is enough power for great production or if more light would be better?
