LED growing- An instructional grow log

THANKS DUDE YOUR REAL TO THE CORE!! I APPRECITE YOU DONT GET YOUR FEELINGS HURT LIKE SOME OF THIS OTHER GUYS! AROUND HERE!

Hey bud, I just started using LED's and I've been doing a lot of research on them.. I can tell you for sure you need more blue spectrum in the initial life of the plants.. I have been trying to figure out the exact ratio of blue/red for veg and flowering clycles.. I want to know how much red is actually needed for vegging and how much blue is actually needed for flowering.. I know obviously you want a bigger blue spectrum during vegetative growth, and a higher red spectrum when flowering.. so I want to figure out what minimum of each you need for each cycle..

well I think you definitely need more blue for veg, but I havent even read the whole thread yet.. hopefully we can chat..

take care good times with ur growing !!

:weedpoke:

not enough blue for veg?...you see the pics?...they are bushier than any time i have done HID for sure...thanks for your opinion though
took 2 more males out today....ick...one is probably going to my house for a few days before i throw it out so i can get the pollen...that would be the test plant for those of you who have been here...thanks guys

if you've checked out the prycon website you'll find out that the led lights put out a perfect spectrum for plants for the whole way through its life cycle. check it out.

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 both for 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 near 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 4,000-5,000 lumens meshes well that estimate.

At the same time, the results you are getting with a light intensity as low as 5000 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 and using only those frequencies of light beneficial to plant growth, remarkable power and light efficiencies should be possible.

And you've done it. Cannabis is not a low light crop by any means, and your data is incredibly encouraging. Once you reach harvest and have yield numbers that can be compared to HPS and MH lighting, you'll show the nay-sayers about this tech. You are demonstrating that LED's time has come.

SnS will have "done it" when the harvest is weighed, and it comes somewhere close to what HID could do.

hey hey hey, stealth their looking awesome!!
quick question about the lights my friend showed me these today:
shenzhen sheng nan electronics co.,ltd
the 3 watt ones would they be better than the cree X-lamps??
peace luv smokeon!:rastasmoke:

thanks for checkin in on the thread. they look great to me too:thumbsup:

dont much about individual LEDs or power supplies and such. they have more power(near two watts vs. most likely near three) though, so its possible. also factor in the lens cost and assembly.

so so true...

thanks again Gilfaethwy (reply in other thread)

ty stealth i don't either maybe someone who does will help out
they look pretty close to same thing to me except cree is like 2 watt and prolight is like 3 watt

looking good nice ladies ya got tasty!!

SnS, Looking good my light is supposed to be shipped here in the beginning of March. After seeing your growth I'm thinking I lucked out seeing the Procyon and checking into your grow experiment on this site. Thanks for the info as well on what you are using to grow anything learned in here by me will be used to help my own growing.
