thats quite impressive.

problem is you cant buy a light like that?. my simple years are long behind me. :bigjoint:

if in flower you have a strain with really tight/dense bud structure really pump channel 3 in bulk (like a 1:1 ratio of 660 to 730 nm) for a more sodium look a like bud. if again you have the opposite something a bit loose/fluffy (admitidly this is rare when growing under normal off the shelf...

all the above is obviously strain dependant, but if you have something that is very small and compact not much stretch in early flower try more channel 2 and channel 3 in veg and stretch. if you have the oppostite something tall and leggy that stretches for fun and has poor internode/bud spacing...

i would have added some uva but i dont hink led-tech has any modeled in its simulator. i would run the mint evos and all the blue monos on 1 channel then the pro9's and 660 on a second channel then just the 730nm on a third channel. a one light does it all solution - veg - run more channel 1...

i had a quick play with led-tech system configurator , i used the 3000k blux f90 as a stand in for the pro 9's and added mint evo's at a ratio of approx 2:1 (2 f90 to 1 evo mint), then added some monos to fill it out. using the 3000k pro 9's should lift the efficiency a bit and fatten out the...

how are you thinking of using the pro 9's? as a standalone or mixing it with another white midpower and/or monos?.

exellent info... thanks for that.

r are you saying the blux f90's are using the same ksf phosphor that the pro 9's are using?. can you remember what the numbers were for eficiency?.

i dont see how its the opposite?, they are more or less the same spectrum. apart from cree offering 3 different spectrums with differing amounts of blue. its clear this is a push for efficiency (the same as the mints) as they like you say strip out as much of the red from the whites as possible...

the pro 9's are cob and high power form factor only no mid powers.

the 3000k "Z" cri pro 9's look like a good base for a flower spectrum.

photophyll looks like crees spin on samsungs evo "mints", great if your only chasing efficiency not so great if you value spectrum.

fek me...

spot on, 10/10...

its absolutely ok to mix spectrums.:confused:

imo mint greens get used to lift efficiency not for the spectral quality. mammoth are using mints plus an emerald green diode.

i have never flowered under the emerald green mammoths but imho there are a gimick. "normal" led's already have ample green i the spectrum, there is nothing to be gained by adding more.

par?, mcree curve?, science ect?...
