I just got a hlg 600r spec . And I was wondering at what distance I should be hanging it from the top of my Canopy . I have 6 auto flower in there third week of flower in a 4x4 tent. I also have the supplemental uv bar mounted on the 600r.
I don’t think I would go any lower than 24", and maybe even a little higher than that would be better. If this is big upgrade in lights, I would dim some so as not to have large abrupt increase in light intensity. Gradually increase a little bit every few days.
Okay. Thanks for answering my question.
You can get yourself a Dr. Meter LED light meter. Not to expensive. Just used mine today setting up my XL 260 R Specs. 2 in a 4x4. At 18 inches I was at Approx. 45,000 LUX.
Note; I dialed them down to 198 Watts pulled from the wall. A watt meter helps a lot as well.
I pulled this LUX info right here on ilgm…
|Vegetative||~70,000 lux||~40,000 lux||~15,000 lux|
|Flowering||~85,000 lux||~60,000 lux||~35,000 lux|
This is a good cheap quantum meter:
I have that meter, except it is branded as Hydro Farm. I used it a few times and it stopped working. Pulled it apart to find the positive wire was not soldered properly and poorly supported. After a re-solder and securing the wire it works again. You can find the Hydro Farm meters on ebay for 65.00…
