LED growing- An instructional grow log

Wow this thread is like the ultimate breeding ground for spammers and threadjacks, lol.
I've removed several posts (and a couple 'members' who obviously are only here to advertise their product or get their hands held) and left only Opie's response, which I hope prospective trheadjackers and spammers will read before cluttering up this log even more!
Grr.

SnStealth, if you don't mind I would like to sticky this since it is an excellent log PLUS a good discussion of LED theory that prospective LED growers should be able to find easily...

well, i would also like to say my friend and i are in the same boat. We had our very first successful grow op, using only flouro's and uv's, we grew 1 mango, 1 sweettooth, and 1 hash.

we just used reg soil, and cheapest everything , lol . each plant only got about 1/8th to 1/4 of an ounce. not much at all, but hey we were happy for our first time, we got some dank bud.


now this time around we heard about all the talk about LED and HPS, well we don't have the money to order any HPS let alone run the damn thing, so we just recently ordered and set up 4 LEDS.

We have 10 femenized blue berry seeds running under these lights.
planted in fox farm ocean floor, and using fox farm nutes.

i'm guessing these LEDS will definitely grow a lot bigger buds than flouros every could, but the real question is.. do they stand up to the HPS.

we bought 4 LED SUNSHINE ALL PURPOSE GROW LAMP SUN BOARDS.

we found them for a great price on ebay. most places want 80-100$ for just one board, and we found 4 of them for $200 by outbidding on ebay.

more info on the lights here.

4 LED Sunshine ALL PURPOSE GROW Lamp Sun Boards 900 LED - eBay (item 220202665770 end time Feb-25-08 14:14:25 PST)

So, i myself am really excited to see what LED's bring to the table. we were pretty disappointed at what flouros did, although i suppose it was better than nothing, lol.

i will def take pics every month and keep ya'll updated! :hippy:

stinky, we would love the sticky.....heh,thanks for the recognition of what we are doing. getting tired of being told we are doing stuff wrong when, well,....look at the plants...lol yeah, these guys dont seem to like us for some reason...lol....from now stinky, i will not flip out on the thread and let you guys handle it;)...........FLOWERING GUYS!!!!!!!!!!!!!!!!:S1:


and WH...you are probably right, i have always done flat white in the past, we just tried the mylar this time for the LEDs....next grow!!

WH:smokebong:

see stinky!!!! sorry mrclown, unless you have been here under differant names....but see maspinos thread...you got china panels...they wont grow pot well at all..if they even sprout sorry to be the bearer of bad news...the only light out there i think you can come close to comparing the procyon with is the UFO....and thats not even really a comparison......


WT

I really like flat white for the simple reason that dirty white paint is more reflective than dirty mylar, lol! The moment you start using sprays, your mylar is going to suffer, and since sprays are so useful, it is a good idea to EXPECT that you will at some point be using them.

Mr.Clown, UV lights (I assume blacklights?) don't do a thing for cannabis. Plus, the initial investment for HPS is LOWER than for LED... ??? Please don't post links to items for sale as it violates site rules, thanks.

I'm sticking this with a slightly altered title - I hope it will avoid more spamming to make the title clearer that it is your LOG- let me know if you want it changed back, or changed in a different way.

Great new title! Thank god the Stinkster keeps them in line. ;)

thanks again stinky...think the sticky and name change will help drastically, appreciate the notice too;)
heres a few pics guys.....enjoy

well, that sucks that its cheap china. they definitely all sprouted and are all growing at a faster rate than with flouros. i guess we will have to wait and see.

and no, they weren't black lights ... they were flouro UVA lights made for growing.

and sorry about posting that as a sales link, just providing more info on the lights :) will keep that in mind next time.

well, like i said i will keep you guys updated, hopefully we didn't waste our money on lights that won't work.

Plants looking good SnS, as usual.

Thanks stinky, for giving people some choice and input on things that happen around here. I've never seen anyone else do that, and it is much appreciated to be treated like an actual person.

Hey no prob; have a look at the new sticky in the top of this section. I feel that the grow logs, more than any other section on this entire site, are a very personal place where each member DOES get to sit up at the front of the class and tell the unruly kid in the back row to shush and listen.
Your threads here are YOUR THREADS.
The only thing is that the site still has a policy that users cannot delete their own accounts or threads, but again, here it's a place where the poster IS a bit vulnerable and if security issues come up I am perfectly willing to entertain those types of requests.
So... ON WITH THE SHOW!!!
Yes! The one with the funny pink plants! :D

thanks for the imput clown, but we would love for you to start your own thread on your endeavors, and keep comments on this one more pertaining to our grow. this is really the only imput, advice, help myself and doughboy can get right now. there is no one else doing this for us to talk/compare to...so without people like opie, stinky, WH, MVP and the other regs, we couldnt get through alot that we have already in this grow. so we welcome whatever you have to say, about our grow. and i would be glad, as im sure others will, to visit your thread and help in any way i can.
:smokebong:

and the mylar will br gone for the next grow...good call guys. i actually think the mylar is hurting us, because were it bends, it splits the light back into red and blue beams, as opposed to a blended light.

Wow very interesting, it creates uneven lighting for the plants. Will remember...

SnS, plants look great. Quick question though...what temp do your procyon run? 2", 6", 12" away from the plant? Sorry if you have already posted this...Also could you measure the width of the plant? Like tip of one leave to the tip of another on the other side. Just because I plan to grow short plants also with LED's, but they look pretty wide and would like to have some data to calculate room size... Thanks!!! :pimp:

no prob...measurements for ya later...almost no heat from the procyons....and tehy do seem to stay short with these lights, i remember my jack herer reaching for the sky, bubbleberry was short though......
WT

mymymy, stealth and his dawgs got the 'led instructional thread',,,,hmm and to think, this started as an experiment.

nice work guys!:thumbsup:

btw-agreed on flat white walls:D

Hey guys,

They got their first night of long sleep and been awake a couple hours, listening to music. they got their first feeding with open sesame last night so we should have some pics of pre-flower hairs today or tomorrow i'd guess. they look happy as ever, so do I by the way:D.

Db:smokin:

im really amped on this grow. i've been searching for affrodable lighting for so long and LEDs are a great answer.
im getting a friend to put to gether a cluster of 50 odd LEDs for me and they're dirt cheap.
congrats on a successful looking grow SnSstealth, amped on flowering pics!

Do you play music to your plants? I have heard this helps but never really looked into...

i swear by bob marley in the room...i have tried all types of music when growing...24/7 radio in the grow room...classical, rain forest sounds, but they seem to love bob marley....supposedly i have read(ill find a link) that cetain sound frequencies do cause the stomata to open wider, we know what that means....but check this shit out...an 8th grader did this... Science Projects on Music and Sound

so its safe to say i am a firm believer in sound aids for plants..and i kept "everythings gonna be alright" looped on a CD player in the room for my last grow...swear it worked...call me crazy

:smokebong:
whiskeytango

Hogwash. You're crazy.

SnSstealth, I've been following this thread closely and i would personally like to thank you for taking the time to post and let us all follow along. I firmly believe that l.e.ds' are the wave of the futre, period. What your doing is not only cutting edge, its straight up no nonsense no excuses .
THANK YOU THANK YOU THANK YOU:thumbsup::thumbsup::thumbsup::thumbsup::thumbs up::thumbsup::thumbsup::thumbsup::thumbsup::thumbs up::thumbsup::thumbsup::thumbsup::thumbsup::thumbs up::thumbsup::thumbsup::thumbsup::thumbsup:

This is probably because of the stimulation of the meridian system of the plant at the range it is most “vocal” in, 100 hertz, which causes the plants to increase their output at that frequency threefold

Found that here:
http://sps.nus.edu.sg/~tanshenm/2171.pdf

Also found this:
The perceived pitch of a person's voice is determined by a number of different factors, not least of which is the fundamental frequency of the sound generated by the larynx. A person's natural fundamental frequency is influenced by many factors, including the length, size, and tension of the vocal folds. In an adult male, this frequency averages about 125 Hz, adult females around 210 Hz, in children the frequency is over 300 Hz.

from: Vocal folds - Wikipedia, the free encyclopedia

So maybe this explains why Bob Marley works well for you SnS...I find it very interesting...I may be right....but for now....:smokebong:

Hi I would goto to your local lowe's.homedepot and grab a 4foot (cheapo shoplight 10$) (bulbs come in 2pack at lowes GE daylight!!) 6500k bulbs7$ ) i have 4 of these in my 2foot by 4ft closet at 17$ea you can't beat it! they also have the 2pack of the kitchen&bath 3000k!! for 7$ those will do much better for dollar than the cfl's peace now back to LED GROW pic's up yet stealth?

any chance youve seen this: liquidreflector its the stuff they use to make lines on the road (or the same theory at least). I may try combining the magenta paint w/ the glass beads...lol.

Db:smokin:

P.S. sorry WH got going and it became techie;):D

I have been working on a light fixture and driving down the road yesterday i asked my buddy were i can get some of the reflective white paint on the road!! and BAM! you got the link sweet! ty:thumbsup:

.....pics up tomorrow!!! got six confirmed girls so far:weedpoke: and NO males...im sure thats because the hermie jack herer pollinated the bubbleberry, so they should almost be all feminized seeds...pretty much, yeah? hopefully when i get off work and post pics tomorrow, i got some more ladies wanting to show off their hoo-hoos for us.....bong

:smokebong:
whiskeytango

first 2 pics are the test plant as usual...14' tall, 17' wide...mmm and its not even one of the bushy ones;) middle pic is the whorly...pretty girl...:hippy: gonna do some light tests to get you guys some better close ups...supposedly an HD camera...but i cant,...whatever...enjoy
oh, last 2 pics are more ooooh aaahs.
:smokebong:
whiskeytango

off the LEDs for a sec, wanted to show you guys the 2 main phenotypes i got with my cross. for the noobs, its jack herer x bubbleberry.... first pic, we'll call her mary of course (look at lil sis growing next to her...suprise seed that didnt germ with the rest), is the more sativa ish plant...thinner leaves, stretchier. the second is the one that has 6 tops...we'll call her titties...my shoice, dont ask. much bushier, wider, and darker leaves....then the last 2 are of the mystery seeds...either its one of the parents, ima stoner, lost the packet it was in, labeled...or bagseed from some WW or skywalker....well know more as we see more titties;)
:smokebong:
whiskeytango

I am still following your log Stealth! Keep up the good work! :D

How long away from floweing now, few weeks?


Peace,
Denial

hey stealth crew the ladies are lookin healthy...if you do get access to the hd camera you'd be able to get some good closes up of the flowers... keep up the good work .. i can't wait myself to expiriment with leds ... just trying to figure out which way to go ,or should i say GROW well thanks for helping us noobs learn a few tricks

later D :greenthumb:

I'm pretty "medicated" right now and don't feel like reading 20 pages...

Are you foliar feeding? How often? Would it be worth it to foliar feed once a week?

Also, can you take some close up pics of the nodes with the preflowers? That stuff is always cool to me. :)

Peace!

That would be true, except for the part where it's not. If you can get them in 2700, or better yet 2450K, then what you're saying could be true. It takes twice as many lumens to induce the same chlorophyll activity at 3000, than it does at 2700. It takes about 4 times as many lumens at 3000 than it does at 2450. So I really don't see how the bulbs you speak of will do much better for the dollar. That's why T-5 sucks for flowering. Nothing below 3000K.

Oh crap, sorry SnS. I thought I was in the other thread. Can't delete.

how long ago did you plant them? how long did it take to hit 1 foot
?
:smokin:

the post is here to READ, i am stoned too, and dont feel like repeating...but..3 weeks foot tall...yes we foliar feed, frequently...flowering for 2 days now....
:smokebong:
whiskeytango

Don't you love it, repeating the same shit over and over? I think it's going to happen in our longer threads no matter what. There are going to be people just tuning in instead of following from the beginning, and they are not going to want to read all 20 pages or whatever to find out how tall the plants are.

PS. Even some of us stoners that have been following from the beginning need some refresher courses from time to time.

Fantastic thread-- i cant wait for the end results!! what week are you on at this point i know we a few days into flower-- but how long did it take to get here i lost track myself... and what do you guys think and addition of these light incorporated into a hps grow? you think they would get all wacky or thrive more... and for the love of god please finish the post-- every other post on led's have vanished right around now - so may the force be with you and keep up the great info!

~420~:rastasmoke:

:lol5: Isnt it ironic? dont ya think? lol

Thanks opie I think sometime tonight or tomorrow morning ill put together a data post w/ as much pertinent info as i can, that way it can be referred back to by page & #. no problem:thumbsup: yeah we all need refreshers now & then.

Yeah they can be combined but we wont be doing that.and the post will be finished , and based on the few led grows w/ inferior equipment and the yields theyre starting to obtain, that it will be a very happy day once it arrives:greenthumb:

:vader1: the force is strong in this one...lol (i must be blitzed)

a daily refresher would be nice. <G>

Seriously though, the thread is going great so far. A lot of discussion on lighting power efficiency.

Sho

Plants look great and healthy is all I can say.

WHEW!!!

Just finished gathering info for a veg/answer post. I will try to put it together into something coherent tomorrow morn. wow this thread is long...lol

Db:smokin:

I'm a newb here but have been following the procyon grow closely with anticipation.

I wanted to know if anybody has a chart of cannabis absorption spectrum? I have a general chart of absorption spectrum for plants but want to see a specific one for cannabis. I have searched for the last 6 hours and can't find one.

I have some engineering experience and from what i can see pretty much all the led grow lights currently for sale totally miss the necessary wavelengths necessary for optimal growth. Its really not that difficult to hit most of them except maybe the 660 which does not have a lot of good choices in the high lumen/watt range but there are plenty of blues to hit the target easily dead on.

If somebody can get me a chart of the cannabis absorption spectrum i would really appreciate it.

check this months high times for the absorption spectrum, right there on(pg.50)-- its in there with a article on the U.F.O.
