So my 3x3's were running a higher watt per sq ft than my 4x8 is. I got in the garden tonight and switched some lights around. We will see what happens. I now have (2) 3K 1812's on a meanwell 1050 driver each one and (2) 6500K 1212's on a meanwell 1400mah driver in each 3x3. I took one cob of each color temp and moved it elsewhere for a new nursery space. To my eye the mixed spectrum looks a lot like the 3500 K does on it's own, but a little more "realistic" like being outside not sure if that makes sense.By optimal I think you mean optimal growth rate, and what you're saying is true but the chart also suggests 75% growth rate at 50% of optimal light intensity, so it makes sense to limit the veg intensity to around 700 or so until we're all getting fusion powered electricity at pennies on the dollar, and honestly even a PPFD of 450-500 is going to provide a fantastic veg if all other parameters are keeping the plant healthy. As far as yield some suggest it's close to linear but my own efforts haven't proven that out yet. Keep in mind I just recently upgraded my equipment and prior to that never used over 800 PPFD in flower. So far, jumping from 800 to 1250 has resulted in an increase from 58-60 to 72 g/sqft. I think I can do better than 72 g/sqft but for the curve to be linear I would need to pull over 90 g/sqft. I know it's been done before but probably beyond my skill level even with these nice lights. And you know, getting 60 g/sqft from a light that isn't quite hitting 800 PPFD ain't too bad.
I've always argued that it's not the most practical thing to grow with +1000 PPFD. Better to use same wattage with more space. But efficiency goes up and price goes down, and I was curious. I'm doing it for science
I'm pulling 228 watts at the wall on the kil o watt meter for just the 4 COB's in each 3x3............let's see how the plants respond. Like you said this is not a lab controlled test but there is merit (i think so ) to the things we are finding with the less is more theory............
Ok I want someone's help here who is better at software stuff than I am. How could I create a chart/graph where I can over lay the citizen spectrums of my 6500K/3500K/3000K over the spectrum of the new Hortilux LED lamp? I would be really curious to see how this compares.........
Thanks guys I am enjoying this thread and the info back and forth
@hybridway2 Tagging you because I think some feedback from you would be killer as well since you have grown a fair amount under HID & LED as well............
And you have the strip lights going forgot the brand but way out of my price range so I haven't been able to get my hands on them
