Guys, in all reality, HPS will slowly Improve over the next 5 years. I doubt there will be anything still other than the DE.
LEDs on the other hand, man
.. WHO KNOWS.
But my point is, where that being the case, CXB3590-'s we all love SO much will be OLD news and new Cobs will be available by then. The real test will be if the people wanting to do large scale grows, will remember just how awesome these little chips are, Right Now. Because 5 years from now, cxb3590''s will be super fuckin cheap and will "seem" obsolete to other LEDS cobs available at that time, Making a 20' x30' cob grow not really that expensive if they did use them.
It''s already doable with vero18's, but Cree has a special place in our hearts.
