LED Grow Test

re: LED GROW TEST. 126W hydro grow led VS. 180W

i read this in Greg Green new book that.

3000 to 3700 CCT in
(warmer yellow netural) is highly active photosynthesis for all stages of growth.

1500 to 3000 CCT in (hot orange or red) promotes flowering.

3700 to 4000 CCT in (warm neutral) promotes rapid growth

4000 CCT (neutral white) promotes normal growth

4000 to 5000 CCT (light blue) encourages good leaf and stem growth

5000 to 8000 (deep blue) encourages excellent leaf and stem growth

so it might not be a bad idea to look into some yellow also. its just trying to figure out what the right NM are?
 
re: LED GROW TEST. 126W hydro grow led VS. 180W

Any idea of the percentage of each Irish?

Maybe it would be a good idea to build an LED that hits most spectrums and use a T5 or something to add whatever is left out just during the vegetative stage. Perhaps we could focus on designing two LED lights, one for the veg cycle and one for flowering like a few members have hinted towards.

i wouldn't worry about veg too much since their a cheap way of using CFL witch dose great for veg.

i rather spend my time and money on the money maker flowering. i dont know the percent. i think it would be cool but costly and time, but take all the higher NM and get them made into some smaller units and do side by side test, witch ever NM did the best in flowering i would then combined them into one flowering light and give that a go and see what happen. i mean we can see threw the charts what the peek point are for plants, so just try to get ass close to that as you can. seems higher then 660nm and just below IR would be good also? i think you guys can figure this out for sure, but it would cost some money to do. if someone dose figure this out don't forget about ur Irish brother lol.

flower is where its at. If someone came up with the right formula they could really make it in this market. Perhaps one could combine CFL and LED in one fixture. Do they make PCBs like that?

You wouldn't get them on the same board, but its so easy just to use $5 domestic clip on lamps for the CFLs, that you dont need them on the same board.
 
re: LED GROW TEST. 126W hydro grow led VS. 180W

Exactly! A flowering LED is where all the focus should be. CFL's for Veg, no worries. Damn, I'm getting excited! Wish I knew more about this stuff to contribute something useful!

I will be supplementing my LED lights with CFLs to provide the white,
6500k for veg stage,
and 2700k for flower stage.
Easy enough to install and very cheap, and more LED space for 660s.

For my grow light, my spectrums will be around 85% 660 red, 10% 430/450 blue, 3% 630 and 2% 410.
And then just supplement with CFLs as required.

I forget where I read it but I believe there are 2 spectrums of red needed. When I get some time this weekend I'll do some research and see what I can dig up.

Yo Irish let me know if you wanna use one of my lights on your next grow.

I give you credit for sticking your hand in this hornets nest with us here. We're getting to be a fair, yet very tough crowd. I'd personally love to see irishboy use your light for another test.

do you think you lights can do better then what my 180w is doing? i am down as long as i am going to get good results. shit even if i could match watt for watt with HID. i keep my growers as real as it gets and i will not BS others on these forums. i am on a mission to find the best led lights out their so i and other fourm members will know who has the real deal. ill give ur lights a chance, so the members can see what they can do.

That and the proper ratios.
I like the idea of using cfl's for the white. It allows the added benefit of using it as side lighting. Save's space on the board for colors that are more expensive and cannot be had at any store.
A handful of IR's. 3%-5%
The question than becomes how much of each of the others to put on the boards.
Now's when i wish these things worked like lite-brights and people didn't just call them that. This way we could just get a box of each color just plug and test till we get it right.

Agreed.


There's enough grows out there with all sort of color and ratio proportions. Most of the work would be to pick through the journals and find out which worked best or what we like or don't like and make changes from there. I mean I've seen first hand accounts from drop ship manufacturers that that is exactly what they did. Anyone with more time than me that would like to volunteer, you could get this ball rolling....

alright guys so i talked to the growledhydro company today and they said their willing to send me a Spectra LED 600w with 11 wavelengths of LED, a grow panel that uses 3 watt/3 chip High Power LED's at 90 degree viewing angle of theirs to do a grow journal on the forums. so after this led grow i will be doing a high power leds grow for you guys can see.

nice one! did you ask for it to be built like that?
Click to expand...

no thats how they make them. they have a you tube video that shows a side by side of the 1w leds vs 3w leds. its crazy, a 3w 180w leds is way brighter then their 1w 300w led unit. i think 420 mag might get mad if i post a link of the video?

if you use their user name i posted with a .com you can find their web site.

That's great to hear irishboy! Starting soon I hope...

starting in a week or 2 when i harvest. i want to clean my grow room real good agian before i start another grow. i also wanted to get some opions on my next grow from you guys. i can do six plants total for my medical use, but was thinking of doing 3 big ass plant LST'ed in 10-15 gal pots. i belive i could beat or get the same amount yeild with 3 big plant then with 6 avarge plants. what do you guys think would be better? please give ur opions on what you rather see/ would be better for my yield?
 
re: LED GROW TEST. 126W hydro grow led VS. 180W

cool thanx, im more interested in the 90w/126w or 180w, dont have much money to spend!! cant wait till i get your verdict on the two you have! ill prob. buy the best one.

Can someone check me on this? I watched the youtube video comparison of the 1w LED and the 3w LED for Grow LED Hydro and at first it was very impressive how bright the 3w was compared to the 1w even though the 1w had almost double the total wattage... Then the captions flashed and said the 1w LED had 120 degree lens while the 3w had 60 degree lens. Wouldn't the tighter lens automatically give the 3w an unfair advantage when being videotaped in such head on manner? Wouldn't the 60 degree lens just focus more light directly toward the camera lens than the 120 degree lens thereby unfairly making the 3w LEDs seem far brighter? I guess what I am saying is the video doesn't quite seem apples to apples. I am very interested in the full spectrum approach they took.

lol, i was just thinking about that. i believe now he is using 90 degree led angles on his lights from what i read on his site. when i get my light in ill let you know how the intensity is. i like the ideal of the full spectrum also. cant wait to see what this high power led can produce?
 
re: LED GROW TEST. 126W hydro grow led VS. 180W

I think any major growth increases would be caused by the addition of colors in the spectrum rather than the increased wattage per LED and hopefully you notice a difference in different stages of the growth cycle like the difference between your current 126w and 180w comparison during vegetation and flowering.

I kind of wish you next test’s manufacture was also using 1w led just to keep that part of the test consistent you could focus on the color spectrum before focusing on power and LED lens degree angles.

i know they use to use 1w leds with 120 degree angles, but changed it in their 2nd generation model. their use to be a you tube video of a grow with 8 plant that were around 4ft tall. it looked real good, but now its not on their anymore. i am interested to see what the 3w with different spectrum's do on my next grow. when i talked to them today they said it wasn't even close once they started using the 3w compared to their old 1w models. the vegging looks great from what i seen in their you tube video, waiting for the flower video coming soon. i like the fact that they don't make crazy claims comparing their lights to hps. i just told him i wanted to at least match watt for watt with HID since i haven't seen one led light do this yet. i would be happy if i could match a 600w HPS with 600w of leds at least. without all the heat from HID. i was told it would at least match HID watt for watt. i don't know how good these leds are? but i like their style of not making crazy claims that never seem to happen with leds so far.
