Good to leave any light you have, but I would recommend placing you HPS horizontally for max light to the canopy. Cheers

Sure leave them. Just don't break them they have mercury in them. Toxic stuff.

HLG 550 V2 RSpec power/height in flower
I’m using an HLG 550 V2 RSpec in a 3x3 tent over one Universal Kush plant. Anyone have experience growing with this light in a similar setup? What’s the best height from plant and intensity level should I set the light to? Don’t want to stress her, just want ideal light levels.

Switching from veg lights to flower lights (blue to red) ?
With autoflower when do I switch from veg (5000k-6500k)blue light spectrum to flower lights(3000k-4000k) w/ red infrared ? Should I switch lights right when pistils start showing or wait until after the flower stretch when buds are forming?

Electrical power calculation
Actual power consumption of lights is lower than led manufactorer says. 25 leds of 3W each = 75W plus an internal fan plus some other circuits,Total power should be more than 75W and i calculated 58.3W overall. Vac=220 , I=0.265A Any ideas?

light intensity for clones right after transplant ?
basically should you treat them like a early veg ? using migro 4 array and it recommends 40 percent intensity at 35 cm away for early veg. or because they are just transplanted should I give them a lower light intensity.
