Hi folks!
It's been a long time since my last post http://boards.cannabis.com/indoor-growing/96301-what-light-spectrum-curve-absorbed-cannabis.html#post1159985
Finaly I have Assembled my LED lights and now growing using them.
Photos comming soon... (tomorrow):thumbsup:

Cool. Pics! How are they doing, how old are they?

Ones upon a time I surfed on the cannabis boards and found a good way of growing by Tranoble, but unfortunately I had only 10k $ for the room build up.
I couldn't offer humidifiers, air heaters and coolers CO2, and suspicious electricity bills from hps. So i decided to invest most of the money in to building energy, spectrum efficient lightining.
Light spectrum info i used was evaluated throug scientific experiments (if you search my topics you shurely will find) carried out by some farmer univercity back to early 1990s.
I have assembled led pannels using that data (30 blue, 20 green, 50 red)
So now I have several LED pannels.
One pannel is 45x75x3.5 cm approx
76 watts 100% PAR
40 Celcium max temperature
2.5 kg weight with 12v adapter.
Plants grow healthy in usual soil from my grannys garden. 10 mother plants give 20 healthy 5 inch tall clones every 2 weeks.

Did you say your max op temp is 40C? Holy guacamole. Up that ventilation! You're looking for about 24-26C.

You know, for $10K, you could build an HPS based grow op (or 10) that would produce like mad and have very little heat signature.

Oh, yes, 40C just 5 degrees away till enzymes start to decay and collapse:stoned:

Are you saying temps for weed are ok up to 45C?

?

Are you saying temps for weed are ok up to 45C?
You are LooL : : ) You missunderstand (what is the right spelling for missunderstand in past?) me. 45C is the highest temperature of the LED lighter)) not the air temp in the grow closet)

Last pic demonstrates my recent transplantation
from left to right
First plant is rooted clone in the soil for three days
Second old clone, transplanted to the proper soil recently
Third 1 day old clone

Attach option disappeared!
What to do to attach more images?

Looks good! Do you have any idea how many lumens that setup is producing? Also what frequencies are the LEDs producing? How much power is it using?

I'm actually just starting a grow with some LED arrays I built. I don't have as many lights as you do though! ;)

Actual light flow is approx 5600lumens, if compare to the sun light according to the PAR ratio then it will be 16800 lumens.
It consumes 75 watts, and the time life is 100 000 hours, which is 10 years of constant lighting.
LED frequencies I tried to match with results of this research http://boards.cannabis.com/indoor-growing/93100-research-lightinig-your-opinions.html

10 mothers are in work, hope soon will be more )
yesterday I have cut 26 clones
today 9

little more

and another

Looks good :jointsmile:

Peace :thumbsup:

Don't say anithig about light intensity before you read and see the crop of mine)
From some older posts:
1. Low intensity of PAR (minimally admissible) - a range of intensity at which growth of vegetative bodies occurs, but are not formed high-grade generative bodies (bud). Thus photosynthesis has low parameters. For photophilous plants it is intensity in a range 15-30 w/m^2
2. Optimum intensity PAR - a range of intensities at which the maximal accumulation of a biomass in unit of time is observed. Thus The part of a useful part of a crop to sheathe makes 50-70 %. Photosynthesis and growth are well balanced. For photophilous plants it is a range of PAR 150-220 w/m^2
3. Sating intensity of PAR - the maximal intensity of light at which the output of photosynthesis on a plateau of light saturation is reached, ie maximal photosynthesis. Thus, growth inhibition of a stalk and other axial bodies is observed - plants get the undersized form. The part of a useful part of a crop to sheathe is high, but the general biomass collects less, than at optimum intensity as growth is braked (400 PAR w/m^2 and more), requres tripple nutrition feeding

LED 40x70 lighter produces 76 PAR watts and if you convert it in metres which is 270PAR watts /m^2, which is 50 watts more than so called optimum par intensity (2). But far away from 400parwatts/m^2. However these calculations are approximate, to obtain clear scientific light intensity must be measured or the yields of plants under various lightening must be compared.
Goal 560 plants 20 lamps of mine

By the way we already can compare results under various lighting.
You can see top fan leafes of my freshly cutted clones from under the l e d lamps in the cup and my first mother from under 4 52watts T5clfs in front of them. Clones in the cup are choped from children of that mother mother cutting in front. They are all the same sort but differences are incredible. I had to cut down this mother and chop clones from her cause I bought distilled water, but its appeare tobe technical distilled water and leafes started to curl downward, yesterday I found many rootings started to grow, would be intresting to observe how her growth will go after transplanting back to soil. Recently I started to buy water in the shop rather than using tap water and the effect was magnificent : clones started to root faster and plants growth increased rapidly.
Can't wait till Ed Rosenthal will errive :weedpoke:
PS
16/8

looks good but i have yet to see a flowering plant under LED that made it, they do good in veg but die in flower, atleast the few threads i have seen on it have died.

even stll you could veg and and keep mother plants while using not even a 1/4 of the electric needed to power other lights,looks damn good i hope yours makes it.

stop taking big clones thats why they look like shit, take a 4inch clone and remove 80% of the lower leaves and they will root faster.

Looking forward to seeing the finished products. I love experimentation. Props for spending that kind of dough on something that might not work. :p

I would've taken the easy way out and did what Al B. said. lol Be cool. I'll be watching! :D


The Fog :rastasmoke:

TGF, hps is no the easy way for me for several reasons, it's bloody hot, it eats loads of electricity, and it's 30% PAR efficient with unbalanced spectrum.
As Zandor says : if you go cheap you grow cheap. Each lamp costs 600$ and 6 hours of work.
Invision it would be grateful, if you would show me some links to those threads

maybe I missed it, but I skimmed thru your links, etc., and didn't find a reference to the green lights - I thought the green spectrum wasn't of any benefit to plants - just curious :smokin:

Here is the link, next time search topics by me.

Yeah freewheelinfrank I think that plants don't absorb much green light at all. Thats why we see them as green, because they reflect most of it.

here we go

another one

Hello!!!

I'm looking foward information about LEDs and i want to find someone who was sucefull in it...

How are your grow?

Thank You until now!

Thank You man!!!

This was very helpful!!! :D

Thank You again!!!!!


:thumbsup:

Cture, Hey What's UP??, Look's like they are coming along nicely!!

Great Job!!:jointsmile::jointsmile:

:pimp::pimp::pimp::pimp::pimp:

Hi all! It's been a long time. I have modified these LED pannels and use as supplimental light with HPS and UV. Look at the topic http://boards.cannabis.com/indoor-growing/155241-unidentified-strain-3-weeks-before-harvest.html

Ya, i would say it's been a While!!!! AAAAUUUUHHHHH, You have been Busy there My Brother!!!!~~~~~~I know there is over 100 plant's in that Room!!!! You are well on the way of Your Goal 560!!!

Great Job Man, WOW, That is a Hell of a Group, & Every-one Standing at Attention!!!~~~~~~~:thumbsup:

:pimp::pimp::pimp::pimp::pimp:

Thankyou hatch!
By the way, clones at the beginnig of this topic are flowered in http://boards.cannabis.com/indoor-growing/155241-unidentified-strain-3-weeks-before-harvest.html

I keep looking and looking and looking at the possibility of growing under LED light, but as of yet I am just seeing pictures of weak veging plants and of yet I have not seen one picture of a good healthy bud on the net.
Let face it if I google kangaroo with bad acne I will find a picture somewhere.
Im not saying you cant grow great bud under led, I hope you can, maybe the growers ive seen so far trying just are not good growers. So please somebody point me in the right direction of the evidence as im a very strong believer in the old saying WHAT YOU SEE IS WHAT YOU GET.
Im waiting :)

here ya go, check the links in my sig.

db:smokin:

How high did you keep the light from the seeds and when did you start your light cycles Im stsrting a thread under procyon 100 grow log if any one can HELP!

10-30 inches

Thanks appreciated Good luck 2 all!!

Heh there

Yep, green is used so you can work in your grow room at night time without fear of disrupting the photoperiod of the plant, they may possibly absorb some, but its not necessary. What is needed though is more UV and white light, either maybe think of adding white to your setup or add a CFL? I know as i am growing that the addiction of white massively helped the flowering stage.

i know LEDS can grow green its just the quality and yeiled alongside traditional methods that is up for question? I think i refer back to somebodys comment about a kangaroo with acne and laugh and agree. I really do believe not enough good gardeners are using LED and too many people believing the hype that one 90watt ufo will beat a 400watt hps. Yeah on one plant maybe! I have lots and lots of these units now, all 1W diodies and they have been a revelation, but you still need a lot of them!

holy thread-necro batman... the stoners must be on the loose.

lol he had 6 x 600W HPS and strip fluros in there with the LED panels... doubt a CFL or two would have made any difference.
