Well I am running a ton of lumens in the 6500k range and adding in 7500k with 60 super brite leds (yea.. ones from superbriteled.com).. Im killing two birds with one stone as well.. as I have it in the 24/0 room burning it 24/7/365 so I can see for real what LED life is like.. I am also insuring they can stand up to the high humidity and constant duty cycle of grow room use.

I think the future of led's for growing purposes lie in two key places.. one being the strings of LEDs that you can buy on ebay:

because people are not thinking outside of the box on this.. why put led's in a fixture like a light bulb?? Thats not productive.. get these strings and hang them from a movable fixture hanging above the crop and just raise the strings between all the plants as they grow. Walla! Make sure you integrate (or alternate) various patterns of different watelength LEDs to achive desired spectrum intensities.

The second thing required will be the availablility of these strings in the spectrums we need without people doing it on purpose.. case in point being CFLs got really popular when you could go to wallmart and find one that operated at 6500k for $5.. and walmart didnt order that light for you to grow plants with..

I hope by the time my HPS system degrades to the point it needs replacing that I will be able to find LED strings like the ones listed above in the RIGHT spectrums for MJ growing.. because if I can.. I mean this guy is selling them for $6.67 (incl shipping) per 6 foot string of 12 1w lights.. 12w per string.. get 100 strings of these and for $667 you have more than a HPS 1000W worth of light, targeted exactly to the spectrums you want, with little heat, and the ability to basically touch the lights to the plants!

The limiting factor now is if those LEDs are in a spectrum that we like?? Its worth a little Q&A to find out..

MonkeyRacket- how is the grow going???
