Just saw where some people were going with HLG lights. For a 4 x 4 room 6 plants. Thanks

I use an hlg 600Rspec in a 4x4 and a 300L Bspec in my veg… I love the results… Awesome lights, excellent customer service!

I have a HLG black bird that is great. Photontek is another good one

Have you run into any stress issues with the RSpec? Which is better in your experience:
-
Higher setting further away from canopy
-
Lower setting closer to canopy
Seems like the lights generate more heat compared to the Maxisun I was using before, but it suspect that some of the burn issues I faced are related to the radiation coming from the additional red spectrum diodes.
Dial is currently set to 6 and light is 2.5 feet (76 cm) above main canopy.
Hoping to get the best values dialed in soon because I have one plant that is 2 weeks behind the others and it would make a nice split test against my older lights

@tswiz Most here would use a combination of the manufacturers recommended “height above canopy” and taking a reading with a quantum sensor, lux sensor, or Photone App to get your DLI (daily light integral = #hrs/day of light x par) for your plant(s) for their stage depending on if it’s a regular Photoperiod or and Auto Photoperiod.
Recap:
Adjust height
Take light reading
Adjust dimmer to DLI.

Sorry… Forgot… I have not had issues with stress…
If I follow the information above, I don’t have any issues.

If you use Photon make sure to Calibrate it to your lights par chart or with another par sensor as it is completely off just downloaded

Thank you @Bracketh I didn’t know that… I don’t use the app… It doesn’t work on my phone.
I use a quantum par sensor:
From what I understand, it more accurate than the others I listed… But not as expensive as an apogee sensor…as it doesn’t need a conversion.

Yeah I didn’t know that either until I couldn’t figure out why my 2 week old felt super dry when rh and everything else was good. Started reading and realized I never calibrated it. Thought I was giving her 25DLI, was actually giving 62 DLI.

@Bracketh Wow… I have a Surface Duo v1… The camera stinks… No matter what I did, the camera sensor gets overwhelmed when I put it under the light and freezes.
Was going to buy the lux meter… A lot cheaper than quantum… But found that lux is completely different than what a quantum sensor does and didn’t feel comfortable/trust with the conversion methods. So I bought the Amazon sensor… Glad I did… But wish I could afford an apogee quantum sensor… Actually would love a few of their sensors… But at hundreds of $ just isn’t in the cards right now.
