A DLI ( Daily Light Integral ) of close to 42 moles/day without any supplemental CO2 worked the best for this environment. For the HLG lights - during the VEG cycle, the LUX reading of 41,500 over an 18 hour period gives a DLI of 41.6. For the BLOOM cycle, the LUX reading of 62,000 over a 12 hour period equaled a DLI of 41.6.

41.6 mole/day is 25,051,520,000,000,000,000,000,000 photons ... according to the International System of Units. There sure are a lot of zeros and commas in that number.

The second flowering with the RSpec, I increased the LUX to near 72,000 - a DLI just over 48 m/d - and without the supplemental CO2, that level was just a little high over the course of an 8+ week flower. The flowers ended up more like what I harvested when I grew with Viparspectra blurples.

To HLG 260s 3000k boards. Save my plant last year when wildfire smoke rolled in. Congratulations on buying the new boards. HLG lights are some of the best out there!

The pic on the right looks like one of my leaves after my dog decides to take a bite. The pic on the left looks like a minor deficiency.

The lollipopping will open up the centre when she gets larger. For right now, if there are a few large fan leaves that might be disrupting air flow in the centre you can remove them selectively to help open it up a bit more.

Do you have a circulation fan on the floor that is able to stir up the air underneath the canopy?

hey man got another question I just got my second hlg light up and running and grabbed that lux app that you were taking about and the new light is reading significantly lower than the other light and the only difference is the driver.

The 260 XL's should have the Inventronics EUM-240 driver. Did you get the wrong one on your 2nd light?

They said they were out of inventronics so they sent them with a meanwell driver but here is what I’m seeing between the two light the boards are different not just the drivers. They are different fucking colors and I’m furious.

So yea I got the meanwell driver because they said they were out of inventronics, so I actually made a post on Reddit and someone on there told me to take the little black plug out of the back of the driver and make sure that I was turned all the way to the right. Which it wasn’t. But when I did turn it all the way to the right that fixed the different readings from my lux meter

So if I had to guess the 3500k is the one with 2 soft white rows and 2 blueish rows? And the veg board is the one with 1 soft white and 4 blueish

... Or are you saying that the Bspec board don’t have any red diodes and instead have blue diodes? ...

Correct. You had asked about their VEG specific QB's. Your pictures above show the red diodes so you would have RSpecs. And glad to see that you found the potentiometer for setting light intensity.

That’s the weird thing the meanwell driver well both of the 240 drivers have potentiometers but this was a screw that was hidden by a rubber grommet. But not sure why these boards are both r specs but have different amount of blueish and soft white diodes. Unless it’s a different temperature color but hlg website mentions nothing about temperature color for the 260w kit. Only thing I can find about that is if I were to purchase just the rspec board it shows a 3500 color temp.
