Jon:
I don’t mean to hijack this thread so I’ll keep it short (
@Rexer laughs about that!). I’ve only done three grows - one in 2017 that got whacked by a SoCal electric blackout, Gorilla Grow autos earlier this year, and my current Gelato autos so I don’t have a lot of history to go back on. The journal from the GG’s has been helpful and the detail from the Gelato grow has helped ID a Cal Mag issue that, thanks to a lot of input and some chemistry magic by
@FelipeBlu, is now firing on all cylinders.
"par numbers vs. uMols,” - PAR, the acronym for the spectrum of light which plants use for photosynthesis, is typically measured by PPFD, which is expressed in µmols. DLI is a 24 hour metric that's expressed in mols. Multiply your PPFD value by 0.0036 and then multiply that by the number of hours in your lighting schedule and that’s the DLI. At 1300 µmols for 12 hours they’re getting a DLI of 56 moles. That’s a whole lotta light!
