you can't determine anything without quantifying what went from what to what..
I'm not completely adverse to your opinion but again.. say replacing 2 Kessil 360's w/ a 450W MH and getting better growth?
NO surprise considering the added photons..REGARDLESS of spectrum.
Same w/ say adding an 8 tube t5 (432W) vs 2 or 3 Kessils ect (270W)..
Adding t5's to an LED array and more growth again, NO surprise considering you are adding more photons..
Adding some Orphek strips might have done exactly the same thing.
Devil is ALWAYS in the details..
I guess some like things idiot proofed, others like a challenge..
No joke I have seen this exact thing at least a half dozen times locally.
“Wow my growth has exploded!”
Oh yea! That’s awesome. How many watts were you using and what did you go to?
“Oh I was running two kessils at 50% and now have 8 bulb t5. T5 rules!”
Not a shock!
Separate thing, isn’t kessil 0-10v and not pwm dimming?
