I am using HLG600Rspec lights in my 4x4 tents. I have a lux meter, but not a par meter, and have researched the conversion (x0.015), but trying to find more data to verify. I have downloaded all of HLG’s posted PPFD charts at various heights. I’m assuming these are all at full power.
Questions:
1. Does par reduce linearly, meaning if my power draw at the wall is half of max (by turning down the dimmer), should par output be half of the max chart level? 1/4 power then 1/4 par on the chart?
2. From a plant’s perspective, is par all that “matters” for growth/avoiding stretching? I’d like to raise the lights some to get better coverage, and then turn up the dimmer dial to achieve the same par. Does this truly create the “same” environment from the plant perspective?
I fried my first seedlings due to too much light, so I’m being very careful now. Thanks.
