LED growing- An instructional grow log

[SnSstealth]

welcome to the forum tranwreck..please direct differant lighting ideas to the first link in our signiture. that is the LED light theory thread. we are an all LED grow thread...
think i may just post this post every 5 posts or so....lol

Hey, Folks: One of my electronic assembly customers is a Phd.
electrical engineer, and we started last month working on an
adjustable, flexible, and updatable LED lamp...have you guys, or anyone you know, been able to match Halide/HPS production?
We are going to be doing grow trials in L.A. and NoCal in about eight weeks....any input would be appreciated. DarioT.

Ehhh, i dont think they can replicate mh/hps yet.... from what ive read, but there trying?...did u read anything on this thread or u just saw first page and post reply?! lol good info if u re and spend the time...ask your ELEC ENG to do it if u wont :S

[SnSstealth]

thanks sticky..took the words outta my mouth. dariot..if you read the whole thread, you might have all the input you want. try the other thread in our signature as well. What are you basing your info on? the high times chart? have you seen pot grown with LEDs. yet? there is alot of info on both thread as to what freq. and such you may need. if you have any questions after reading up, we will gladly answer them. but please post questions in the appropriate thread. thanks for your input and interest in LEDs. good luck to ya:thumbsup:

as of now, it looks like we are on par with HIDs. but we wont know till harvest...stick around a few more weeks:jointsmile:

Agreed.... LOL

Although it could be done depending on bulbs price could be very costly to replicate. To duplicate HPS or MH there is still a way to go.

You can go here and they will build it for you.. Then there will be engineers telling us if infact it is possible to get the perfect spectrum. They have equipment that is necessary to test all this shit. I guess you can build then send out to have it checked and mesured or just grow.. LOL LOOKING @ there plants 1/2 way finished almost. They still have a way to mature which can be done. My friend just harvested a crop less the 4 weeks ago. 3000 watts 3 1/2 Lbs. Looking @ there equipment and plants I think a good yeild would be 1 1/2 Lbs. It's costly to go led if you spend $1800 on lamps and dont yeild 1 1/2 then thats bad. They will not be ready for large grows anytime soon. Thats just my opinion.

i would think 3lb outta 3kw is actually low, remember we are at only 300w. are you talking about an LED grow? how is an engineer not growing pot gonna tell anyone if its a perfect spectrum? perfect for what? anyone can have an IDEA what would be the perfect spectrum. you dont need to be an engineer for that. pshysics or opie aren't engineers? as far as i know...lol physics is already building an array, as is veggii. we appreciate your interest, but thats the second time you have posted to those LED manufacturers. some of the admin. which i am not by the way, might call that flaming, or spamming, not sure what they call it. i would love to see some pics, or a log on this grow your friends did. got any info?

Looking good so far SNS! I just went back and compared your last photos to my last grow...your 4th week of flower looks to have a bit more on the tricome production than mine did :thumbsup:, of course that small of variation could very well be genetics, ferts, ect....I'll take it as a good sign for LED's.

For comparison sakes mine was NLX in soil with 400 watts of fluorescents, 4 weeks veg. Yeah I know most everyone wants to know how LED's compare to HPS, but I'm easy, for me it is looking great so far.....it is looking more likely than not I will be going LED in the near future.....:smokin:

Keep up the good work!

really getting tired of this shit....if you don't like what i say, get the fuck outta my thread. there, thats hostile for ya...

That's nice..


SPAM don't think so... Just some research..This whole LED started out with NASA and the space program not you

Wow you can't be more of an asshole Stelath YOUR GETTING ON MY NERVES? I'm done with you your blocked.

Your Friends are cool. They sent me REPS for my post on led's Asking me more info buddy.

This whole LED started out with NASA and the space program NOT YOU.

Hey They don't test anything NASA in there advancments? There just a bunch of assholes like you stealth. You know I did do a little resarch on LED and was told they can mesure the light and draw it in diffrent ways. Even thought about possibly designing one. Maybe Ill just back PHYS. Was going to take a trip to Cali to sit with there engineers to see if it's feesable. To run test to reach maximum output.

Ok grow up I'm done with you your blocked.... You can bring a JackAss to water but if he does not drink he is still a JackAss.. LOL anyone want procyons just order and wait 3 days.. BLOCKED

how is an engineer not growing pot gonna tell anyone if its a perfect spectrum? perfect for what? anyone can have an IDEA what would be the perfect spectrum.

well honestly I've been thinking about what the "perfect" spectrum should be. and i have a couple of ideas. first, by best do we mean efficiency? or actual absorption? on the high times chart there shows to be pretty much 100% absorption at 425nm and 660nm. thinking about this i started thinking...if we provide only 425 and 660 then most of our light we supply in those two wavelengths, and if the charts are correct, will be absorbed almost 100% , meaning almost almost all of all the light energy we put out will be absorbed by the plants, making the LEDs about 100% PAR (right?). isnt that what we want??? do we really need to hit these other peaks (440,470,642,etc.) or can we just supply these two wavelengths, 425 and 660nm? having more LEDs and colors will reduce efficiency but also increase absorption by the individual pigments. as of now i don't think i could answer these questions. but with some testing i think i can. i will perform a test with 425 and 660 on one or two plants and on another ill try all the peaks, and form there we can compare the results, and hopefully that will tell us if supplying just 425nm and 660nm is just as good (and even more efficient) than providing all the peak wavelengths. as of now 425nm high-power LEDs are not commercially available, so this is one limiting factor. also 660nm high-power LEDs are a new development and still have some improvement. also blue light has more energy than red light, so providing more blue light in the array would mean more PAR or umol/s/m^2. but we still want to keep the light ratio of red to blue right at about 2:1 B:R for veg and 7:2 R:B (something like this) for flowering. I'm starting to think about this whole "peak" wavelength we've been talking about for a while. do the peaks even matter? at 470nm there is about 81% absorption for all pigments and about 77% for chlorophyll b. im just tossing ideas around here. :rastasmoke:

oh fuck wrong thread...sorry SnS!!!
