LED Grow: 1st grow, 56W max, Northern Lights

[maspino1]

is this nute burn or N deficiency?

Wish I could help you Maspino....but not too much knowledge on the subject

[maspino1]

thanks anyway physicsnole. it's cool now, i guess after i flushed the coco out the plant regained
its health

[physicsnole]

Good. Are you still using the 56W (or whatever they are) LED panels??? JW. Would like to see more on your LED experience.

[maspino1]

oh, there's nothing more to see about those retarded panels
i just use it as extra blue light along wtih my t5's now
so now it's really 61W worth of led and fluorescent together

I think your plants look to be having great results a foot at 3 weeks is great i have mh, hps, t5ho, all at 400w. i use them all differently and ive noticed different strains perform differntly between them i use t5 generally for my cloens on to mh then finish hps thanks for experimenting ive been wanting to go led ive heard you run nutes of half ppm with led and i run just a lil more than that with my aero so aside from power you could save money on nutes even as a suppliment it looks great:smokin:

SnSstealth,

I'm yet another of the newbie lurkers who joined to watch your thread

Sir, I must say, you are a Visionary, a Pioneer, a Scientist, and from reading your posts on the forum I believe a Gentleman as well.

This is absolutely astounding and revolutionary work you are doing, and I applaud you for both taking the plunge on this experiment, and for sharing the data on your results as well. I hope you continue and share data about your final yield.

Of course I didn't pipe in to merely to shower you with gratitude and accolades, I do have some thoughts to contribute to the discussion on LED grow theory.

One of the earlier posters in the thread said something about how you are the first to do an LED grow with "close to half enough lumens" or something like that, in a tongue in cheek sort of way, but I think he was on to something.

There's a lot of stuff out there now being sold as "LED grow lights" that is really just snake oil. Most of the products just don't put out nearly enough lumens. My rough calculations about the Procyon 100's indicate they should be putting out somewhere between 8,000-15,000 lumens each. Your measurement of light intensity of 4000-5000 lumens meshes well that estimate.

I don't mean to insult other posters, especially maspino1, but I think he got ripped off. There's way too many scammers selling junk that just isn't capable of getting the job done.

At the same time, the results you are getting with a light intensity as low as 10,000 lumens is absolutely astonishing. It's comparable to 50,000-100,000+ lumen Metal Halide and Sodium lamps. It's a remarkable vindication of the theory behind LED grow lighting. By which I mean the theory that by using LED's spectral selectivity to produce only those frequencies of light beneficial to plant growth, remarkable power and light efficiencies should be possible.

And you've done it. This is also another example of a tragic casualty of the war on drugs. Cannabis is not a low light crop by any means. What you've done is publication worthy research. Research that would propel high density agriculture ahead by 10 years at least! And It's going to go unacknowledged by prejudice and bigotry.

Again, I applaud and congratulate you on this important work and look forward to hearing more!

WOW! thanks alot

kudos for reading the whole post:thumbsup...then posting it in maspino's...lol). j/k

i agree that most LED grow lights are bunk snake oil, stay away from ebay. the research ive seen on the prototype of these lights have shown they can grow tomatoes just fine(i know, i know).

Lumens however are a stumbling block in this endeavor. we believe that the lumen output is higher in the right spectrum due to how lm are measured and the losses of HID energy to heat.

and there are still people telling us we dont have enough blue for veg...lol

I'm pretty sure that some of the 50 or so theyve sold will go to legal researchers that will get the ball rolling.

thanks again,
Db:smokin:

Oh dear!

maspino, I'm sorry for posting my previous post in your thread. I was trying to figure out where my post went and then posted again in SnSstealth's (which is where I meant to in the first place).

I had a bunch of windows open with threads I was following. I must have hit reply in the wrong one!

[maspino1]

it's cool, no heat bro
i gotta agree with you, i was totally ripped off
but it's all good, lesson learned
my plant, frank, is doing better with 2 t5's and 1 led panel now
im trying to find the thread for my other plant lucy, she's doing great
coco, t5 and nutes seem to be doing great for me, she's huge!
