LED grow lights... input please.

Its amazing how much credit NASA gets in so much credit for their "inventions". A majority of the time they have a need and other corporations create these technologies for them. Like mylar, created by the Dupont company(along with many others). Just ranting I guess. remember that anything in space was built by the lowest bidder:wtf:

Funny facts wind power, photo cells have yet to make ONE CENT.


Yeah wind & solar power don't workostexcuseme:

people are living off of the grid just fine...

do u know how many wind turbine and how much solar and energy is sold back to utilities here in calfi....sayin it dont work dont make ya sound to 'telligent ya kno

So if the point im seeing here is to get the correct ammount of Red and Blue ratio during specific stages in the plants growth cycle, does this mean a grower would have to change to color scheme along with it? or would you be able to use the same set-up the entire grow. im sorry if this doesnt make sense im trying to grasp this whole LED concept.

from what i read if you watch what your plants are doing (either streaching leaves too large or too small internode spacing) you can actually tweak your ratio and add whatever portion of the spectrum is needed to get maximum growth.

remember once upon a time there was only MH lamps available for indoor growth and look at how the industry has evolved. the author of the above cited report is now working on his own LED matrix BUT what hes doing is making it adjustable so that you can "dial up" what your plants need.

i would imagine like in all such ventures and taking into consideration the need to simplify for marketing and economic reasons, soon someone will develop 2 or possibly 4 different matrix - 2 seedlings and veg stages and 2 flowering stages one for onset to develop more flowering sites and to swell up the buds in the final stage

supposedly the 3 we are using say the red Nms vary. and the blues are set. they did to tests with "tomatoes" too. that was an amazing plant in and of itself...lol im happy with just getting equal yield. all the talk of stronger potency and some of the stuff in the High Times article this month, well....we will see huh. and hell yeah, i wish they would've made it adjustable somehow as far as the blue/red intensity at veg/flowering. we are using these lights all the way through, just changing the time at flowering.

and ziggy, your right on point as far as everything i've read as well. people are saying they wont work cause they were testing with cheap china panels. we have 3 procyons in a 2 x 8 closet...hopin for a hella harvest...lol

i dont know if id risk the entire crop the 1st time around. its not my grow BUT if it was id partition the last 2' of it hang jjust 1 PROCYON and then hang like 2 4ooW HPS lamps over the rest. it seems like - for now theres a lot of manipulation that you need to keep up on - from the report.

....'"Red needs to be strong. Bring the blue down until all growth stops, but maintains good leaf and stem strength....This should force blossom stage and if stressed properly, good blossom performance. Once number of blossoms are satisfactory, increase blue back to that point where plant leaves and stems get just healthy looking and strong.'".

the reasearcher closes his statement by giving this opinion.

.... '"Opinion: Blossom stage still needs work, HPS is still better at the 1/3 LED/HID, but I believe from what I've seen, that a lot of bad blossom performance is being caused by stretched veg growth in every LED grow I've seen. You must pay attention to the veg stage to have a good blossom stage.'".

this we can all understand with the new lights i would think that here what we need to do is make sure they are hung at the right height. refering back to the report at.... Untitled Page the reasearcher did construct a grid to evaluate lumen dispersion at not only reccomended height but several others as well. from looking at it one can see that the optimum is at 24". now i dont know about everyonelse but what we do is keep our babies short (2.5 - 3' tall) asa result if hung at 18" above the canopy most of the nectar part of the plant will be at maximum exposure thru out veg producing maximum results.

as far as claims of better faster bigger i know that will come. what the real concern here should be is power and cooling - i.e. if i can veg w 400w instead of 1200 and flower w 800w instead of 2400ive saved 2/3 on enegry in lighting and at least 75% in cooling and of those two cooling is what should be most considered and of the most importance. ya cant grow killer nugs unless you provide optimum environmental conditions for cannabis thats like 80 - 85 degrees lights on - and the most important 15 degree (or more) drop at lights out. do you have any idea how hard that is to do in july in calif? the NO HEAT LED is what will change the entire face of indoor horticulture.

Turtle420, Whats Up. I read in the start of your trhead that you were working with a lighting company great news!!! You might want to add to your list of(nm) from 400 to 480 Ultra Violet, and 520 to 560 green,( they do need alittle) 640 to 720 some yellow to orange, You already know about blue and red. You need a mixing board in the resister @ relay circuits, So you can fade your on coluor for veg @ flower in all your panel's. They have 10mm leds they sould be the brightest. Good luck with your project, Good research and development is always one giant step forward for the future in growing. Hey it takes Pioneer's to step out of the box and be willing to take chances in failure to make strives forward. Good Luck, Later

:thumbsup:It's great seeing all this interest in high power LEDs. When I started looking in the middle of last year there was very little to none. I believe with the long testing times and variables of lighting that we need as many collaborators as possible. My only caution on the adjustable lighting is during each separate test the ratio stays the same, one for veg and one for flower, ie. "10 days in to flower and there not flowering well, let me add this". Anything else would lead to confusion. After our first test is complete i'm thinking of adding dividers with diff. light ratios in each. However I'm not really capable of ordering individual LEDs and putting them together and I dont want any e-bay china lights. Supposedly HGL is going to put out a 14W cree do-it-yourself kit which would allow for some tinkering...gotta go check on the girls....

P.S. anyone know where I can pick up a three month timemachine...lol

HI ALL, Ya'll need to go to http;//www.chauvetlighting.com and feel free to look at all the good light's. But on the Home page when the LDI 2007 BEST BIG BOOTH AWARD flashes click on the display, Wait for the real payer and watch the video and see the potintial and mix-ability you can get with the LED's.
