I have never used that exact bulb. 20 years ago i did a grow from start to finish with Metal Halide. I found the buds were airy and fluffy not tight and dense. Hope that helps.

How to make stronger smell and flavour in DWC grows?
Hi guys. Just harvested my second ever harvest, and 2nd time with DWC. Using HPS, then CMH for last 2 weeks I'm really happy with buds, but the smell is a little less intense that I would like. I have used Cannaboost, which is supposed to increase flavour but I want more! :)

How to tell if light is damaging plant?
I'm using a Mars Hydro Ts600. Manufacturers advice is to keep height at 12'' minimum above the canopy in flower but other growers report it can hang as low as 10''. In identifying optimum height how would I be able to tell if it was too low for my plants? What should Iook for?

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.

Light Distance - 3 plants are taller than the others...
Hi all. So I have 6 plants with a 400w HID. 3 of them are about 10-15CM taller than the others. My light is currently about 45CM from the top of the tallest one. Would this affect the shorter plants negatively? Should I raise them to the same level and up the light to 60CM rather

Plants Growing Taller Than Light
My 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?

Longer Light Cycle - Mid Bloom
Is changing the light cycle of an autoflower from 18/6 to 20/4 in mid flower too stressful? Doing so would bump my DLI enough to keep my existing light through harvest. She sleeps like clockwork but less so now in mid flower. Will she adjust in a couple days to a longer day?

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

OK to switch from 12/12 to 18/6 for auto in flower?
Is it OK to switch an auto from 12/12 to 18/6 when in flower (2 weeks)? I moved the plants from the attic which was way too hot and tried the 12/12 schedule to reduce the heat. Now that they are in an AC spare room wondering if it would be worth switching. Appreciate the support!
