Cannabis flowering stage 12 h /day =
PPFD Top of canopy sits 924umol/s/m2
12 hours in seconds,
1 hour has 3600 seconds
12 hours has 43,200 seconds, just multiply duration of seconds by PPFD at top of canopy. Which was precisely 924 umol/s/m2
43,200 x 924 = 39,916,800 micro moles or umol/s/m2
Which equals 39.9 moles or 40DLI
Plants can receive 60 mol/m2.day in the right conditions and still increase their yield.

Rhythmic exposure to moonlight has been shown to affect animal behavior, but its effects on plants, often observed in lunar agriculture, have been doubted and often regarded as myth. Consequently, lunar farming practices are not well scientifically supported, and the influence of this conspicuous environmental factor, the moon, on plant cell biology has hardly been investigated. We studied the effect of full moonlight (FML) on plant cell biology and examined changes in genome organization, protein and primary metabolite profiles in tobacco and mustard plants and the effect of FML on the post-germination growth of mustard seedlings. Exposure to FML was accompanied by a significant increase in nuclear size, changes in DNA methylation and cleavage of the histone H3 C-terminal region. Primary metabolites associated with stress were significantly increased along with the expression of stress-associated proteins and the photoreceptors phytochrome B and phototropin 2; new moon experiments disproved the light pollution effect. Exposure of mustard seedlings to FML enhanced growth. Thus, our data show that despite the low-intensity light emitted by the moon, it is an important environmental factor perceived by plants as a signal, leading to alteration in cellular activities and enhancement of plant growth.

"Fortunately, there are other researches by Langley in his work on "The Temperature of the Moon", with the aid of which it seems not impossible to determine the absorption of heat by aqueous water vapor and by carbonic acid in precisely the conditions which occur in our atmosphere." Since moonlight is reflected sunlight, it has a similar spectrum [10] but at its maximum (i.e., a full moon), by one account, only about 0.0002% of its intensity [11].
... The moon also reflects low-intensity sunlight, although not enough to be used by plants, researchers are still exploring lunar agriculture [121,122]. It was confirmed in a recent study that moonlight affects plants' life cycle, and the moon's state at the time of planting is related to germination, growth, and flowering of seeds [122]. Increased levels of phyB and Phot2 proteins in mustard plants exposed to the full moon were accompanied by increased levels of stress-related proteins and ROS detoxification enzymes, resulting in accelerated growth of mustard plants [67]. ...
. Moonlight proteins are receiving more recognition in recent times (Urban et al. 2003;Klis et al. 2007;Castillo et al. 2008 Moonlight proteins appear to be ancient proteins, appearing early in evolution before the separation of the biological kingdoms (Jeffery 2018). Moonlight proteins have been reported in plants, associated with biotic and abiotic stresses (Jeffery 2018; Breitler et al. 2020;Turek and Irving 2021); in humans, they have been associated with cancer and neurodegenerative diseases (Molavi et al. 2019;Huerta et al. 2023). In pathogenic bacteria and fungi, moonlight proteins are virulence-related proteins (Franco-Serrano et al. 2021;Arvizu-Rubio et al. 2022). ...
