Hey all, so I have a 1000 w hps system and I'm using a parabolic reflector. I got a few apps that measure Lux and according to Internet resources the absolute max I want is 85,000 Lux or risk light burn bleaching etc. Now I had my plants about 3 feet under bulb (tip of bulb mind you because parabolic) and the Lux meters were registering like 125k. The app I used was compared against a Milwaukee light meter and they were within like 5 percent of each other so my thinking is The apps are reasonably accurate.
This is a paradox to me as I keep reading the plants should be 1.5 to 2 feet away from light and yet at that distance it seems the light intensity would be around 175-200 k Lux. These two concerns about light intensity are at odds with each other.
Also the bulb I'm using is old so when I put new one in for flowering I can only imagine there would be even more Lux.
What do I do? Hold my plants further away and ignore the advice of two feet? Or move my plants closer an ignore the Advice about too much light?
P.s. I'm purchasing a cool hood and they say you can go even closer like within 6 inches of cool tubes ...... Once again this is at odds with the 85,000 Lux max
