When I started a few min back I was reading some white sheets from NYU and SoCal who were both doing research on the LED currently in production (excluding Home Made) the Study focus on the usable waves lengths prioritized by Photosynthesis The study was inconclusive and no one LED manufactured to date was over the top better than One.
But out of the 46 units tested, 3 were above average, 8 were good, and the rest were lower Bin Junk no one should waste there hard earned dollars for. The BML is used Commercially thru-out Baudoin the united Arab Emirates and vertical growing green houses all over Japan In multi million dollar automated Gardens. They are one of the three. Thats all I will say about BML. what I have seen id Optical lens studies to pinpoint the wave is as critical as the LED itself.
Its all fun
How would ya like to have this as your clones house
The more we learn and share the better the choices we can make
