Took my ppfd metre outside in direct sun and I couldn't make sense of it lol 3000 ppfd or so. Had me wracking my brain on how a plant can even sit in that light for any length of time,
Let's say you sit it out and from 6-12.
60seconds x 60minutes x6 hours = 21600 seconds. If it gets even 1500ppfd per second for the 6 hours of morning that's around 32,400,000 micro moles or 32.5 dli.
12 till 7 of diffused light should be a nice cooling off , more than enough to make up the missing dli.
Everything I wrote is ofc dependant on weather but you get the idea, thing I noticed about outside is the dli is often 40,50,70, 90 dli.
The "DLI cap," or the maximum daily light integral a plant can effectively utilize, is set by the plant itself, once reached plant shuts up shop for the day.
Think of DLI like a bucket. The bucket represents the plant's photosynthetic capacity, and the tap (PPFD) represents the intensity of light. If the tap is turned on too high, the bucket (plant) can overflow (be damaged).
Plant has mechanisms which deal with excess light, this is when it gets into stress, stress acts on the plant as a whole across many factors, so make sure she does not suffer from multiple stressors at the same time or it may push her over her tolerance level.
High ec, skewed ph, drought, temps, light, smoother you can make her run the more excess light she will be able to handle before she shows signs. The guy who is doing a Scroggins and topped 6 times and us running 80 dli is going to notice drastically different responses from a perfectly ticking efficent 35-40dli.
Balance. It's not a big deal until it's a big deal.
