yeah those secondary lenses really do magnify the output but the footprint is smaller than a led without them.
I think marshydro came back with their own video explaining that, they put some lenses into a MARS II unit to compare PAR with another unit without them.
What about Umoles? isn't that the correct way of reading output? PAR this and PAR that. theyre should be more information than just PAR readings, besides, all those grow journals with the MARS II sort of proves it.
As far as the platinum led goes, I myself have used the eshine version, or original? it doesn't matter... anyway, I had good results with it, I thought it was a good led, results were good, it was fairly quiet running and it stayed relatively cool.
Gave it away to another mate to try and guess what he also had? yup, a MARS II 700W.
The 3g was over 4 plants, the Mars over 4
Well after a couple of weeks you could clearly see the difference in growth under these leds. the Eshine one was getting lots more vertical growth compared to the plants under the MARS.
But....wait...it aint other yet... lol... when harvest day came, both lots of plants looked totally different, the 3g were tall and lanky and coated in buds, the mars plants grew sort of lanky but only had fist sized buds at the tops. ? lollipop buds.
all plants were the same cuttings from the same mother plant aswell. Did make us laugh. was a odd thing to see.
Strangest thing about it was the yield were both the same! even tho they looked so different they both yielded the same dry weight.
So, yeah, head fuck. lol. I try not to think about it too hard these days, I prefer just to go on results,. but if its true readings ya want then its Umoles youll be needing. Not PAR.
