thanks, yes i am also a bit surprised how low i need to drive em.
i think youre right, it will just take a little more to get above 600 ppfd in the 3x3, i havent tested.
would need to make a complete par/ppfd map, if i find time and sense for it and have no plants in the tent.
i can not tell what i will need in flower, have the option to play a bit with the 3000k/660nm ratio and max power.
if the trend continues, i would say a XLG 200 driver instead of a HLG 320 for the 3000k EB3´s in the 3x3 would be just fine and cheap.
always depends a bit on what youre looking for, i want to give them the max they can handle (without extra Co2) and will probably have a very sane power usage.
the wattmeters arent the most precise, but theyre ok to get the picture, the spectrometer should be pretty spot on.
i have over a half dozen of these wattmeters, different forms, and they show almost all the same, within margin.
i think i can veg with 80w total wall draw perfectly fine in my 3x3, aiming for a good 400 ppfd average.
that will be probably my target in the future to not burn the plants.
of course what i see is just true for these plants i have there.
my nutrient regime is maybe not perfectly dialed in, especially in combination with our beloved strong led light.
overall the plants arent unhealthy, have a good amount of roots and some more biomass now,
still strugle to get them taking the 100w wall watt, still have droppy leaves 3h before lights out.
the thread you linked is a interesting read, thanks.
would be interesting to see what he nowadays would achieve with some recent stripes, boards etc., especially in regards of spread.
his meter is nice, goes down to 360nm, only thing i am missing with the C7000.
i made out of curiousity some under leaf meassurments allready and can just confirm what is knowen allready, all.
i can post some spectrum with and with without 730nm, meassured through the leaves if you want.
