LED LightBlaze 400 Grow

There is this guy on Cannabis.com - Medical Marijuana, Medical Cannabis, California Club, News, Videos, Dispensary, Co-op, Co-ops, Menus, Reviews, Los Angeles who has done about 2-3 grows using mainly LEDS. His 1st grow was entirely LEDS. It kind of inspired me to check them out myself. I already know they are not HPS equivalent and i am not trying to get grow with LEDs to prove or disprove that notion. It's just that in my living circumstances, the utility i would achieve with a LED opposed to the drawbacks i would undergo using a 400 watter make it ideal.

The cons are the hefty price tag. I guess i could just get tons of CFL's for the cost, but the problem is that i have been reading a lot on CFL grows and don't want to go that route.

I'm hoping the setback from LEDs will be recouped over the next few grows and essentially they will pay themselves back in efficiency.

I do realize that there is a lot of LED talk on RIU, however i find that Cannabis.com - Medical Marijuana, Medical Cannabis, California Club, News, Videos, Dispensary, Co-op, Co-ops, Menus, Reviews, Los Angeles seems to be the leading forefront with

SnSstealth being the owner of i think 4 procyons.
Here is his original post that his inspired my own experimentation with this new and developing technology.


Off the bat i will tell you that the results of his grows, do support the notion the HPS is still the premier grow light. However LED's are not a bad option for a grower restricted by certain restraints.

Another thing i am looking forward to is the dank cannabis i will be smoking at the end of this journey. Supposedly, because LEDs do not utilize the full color spectrum, the Red and Blue LEDs stress the plant into producing copious amounts of resin during flowering (don't quote me on it, but i've read it). So while i might not have as "Many" buds, they'd still be as dank.

I haven't started flowering...i'm still going about to obtain 2-3 more strains so i could bump my plant count to around 6.

I just got my LB400 yesterday, so today is the 2nd day of my plants under LED lighting (they have been under 2 T5's for about 2 weeks). I use one 23w 2ft T5 as supplement lighting for veg.

I'm hoping to be in flower by the end of this month. Or maybe start Mid this month, and keep introducing SoG style clones in the grow cabinet and just keep flowing until god knows when.

Overall I'm still working out the kinks, and mostly likely will get either a 50-100 watt HPS or a Few CFLs to supplement a more full light spectrum, so i can get the max yield, but using the LED as my primary light.

Here are some pics. One of the plants has some nute burn...then to make matters worse i over watered...so now i just have to kinda wait it out for the plant to bounce back.

overall i'm happy with the direction...just a bit curious as to where it will lead me.

Edit: As for the current strains. The Deep Chunk x Strawberry cough (square pot) has some nute burn (trying to veg it into a mother to take some clones and maybe SoG the strain). The one in the upper right in a Hindu Skunk x Shiva Skunk B clone that i recently acquired (upper right). The Upper left is Bubblegum. These have been under 2 T5, but now with the addition of the LB 400 i'm eager.

I'm watching, They don't have to be closer to the plants?

While the picture might fail to show it, they are within ~10 inches of the light.

So LEDs don't need to be 2-3in from the tops like fluorescents?

No, from what i've read, while having them closer will increase the light, but due to the fact that LED lights are made up of X number of Red and X number of Blues, the closer you are, you reduce the spread of the blue light. So the manufacture recommends the lights to be placed from 12-24 inches. However after reading other ppl's LED grows, i have come to the conclusion within ~12 inches is great and fine by me. I'm sure you could get away with maybe ~4-8 inches, but i won't adjust the light until the plants are closer.

Update: The plants are responding REALLY well to the light, much better growth in the last day (2 days) than with maybe a few days of T5 lighting. At least it seems so.

the best way to offset the disadvantages of LEDs is to use them primarily for SCROG. A well-trained scrog with LEDs and T5s would get you some good buds and a decent amount off a couple plants.

i did an led gro it was killer i sublimented a single ufo with 1000 watt hps.

and despite all the negative hype the led did make some dank ass bud.

sorry to be a pain in the ass on this but until i see a 100% led grow with some killer output i am not gonna be convinced

and i have heard it all before
the spectrum is what the plants want!!
if this pink light was what the plants needed then hps would be pink and it is not.
you want yield?
get led to provide an hps spectrum
then get back to me

I love it how people don't read anything, misspell everything, and jump to conclusions faster than they can think.

SnsStealth GROWS WITH LEDS. Procyon 100's which are the similar to the light i am using, LightBlaze400. Please read over peoples successful grows, before you just bash mine. Linked is his 3rd grow with LEDs. His early harvest, and you can EASILY see the copious amount of resin produced.

Also, if you are just going to talk shit, please refrain from posting on my grow journal. I know leds are not hps, and i'm not trying to get an equivalent quantity yield. i want to minimize my wattage usage and get the most potent buds i can produce. LEDs suit my purpose, and thats why i am giving it a go.

I've thought about that...but i'm going refrain from sog/scrog at the moment until i determine what strain is ideal for my operation.

i've done some research and apparently certain strains perform better than others under led lighting...so i'm going to utilize my first grow as a cornerstone for determining which of strains being tested performs the best.

I'm sticking to mostly Indica dominant genetics in favor for their short height.

So far the bubblegum seems to be growing the most robustly in veg. However, i won't know for sure until after harvest.

yes multan ppl really shud read wot is writen before posting i myself have bin researching leds for almost 6months and hav just purchased a homebox n im getting a procyon 100 im aiming 2 hav a couple of low-med yield plants real stealth like. leds r the future y r ppl so scared of change lol good luck m8ty im following this 1! keep it up.

Ain't nobody scared of the future. LEDs are going to continue to be overly expensive because the same material they're made from is used in making solar panels. They're going to never produce any proper amount of light penetration, and you're not going to get any decent results. NASA is only using LEDs to grow lettuce in space, nothing else because they figured out IT'S NOT FEASIBLE. My high school did these exact same tests in Hort. Sci. class, SAME RESULTS. Lettuce and other thin-leafed plants do fine, anything else just didn't do as well with LEDs compared to HIDs.

Quit listening to the MARKETING, take a few material physics and horticultural science classes, Learn about the inverse rule for light over distance, learn about light penetration, PPFD, the two types of chlorophyll and what specific wavelengths they react to in each plant type (because most LEDs don't match the actual wavelengths varying plants actually use, so you're just wasting MORE ENERGY on a wavelength that's being ignored, plus you can't detect it but LEDs shift their color over time.)

I've used LEDs for years and years. Trust me, about the only thing LEDs are good for might be keeping that orchid you have in your house looking happy and pretty, and keeping the blooms on it longer since you've not bombarding it with UV.

If you want to do REAL LED GROWING, you're going to need a DOME of very, very, VERY powerful LEDs. We're talking 5 watts PER BULB, *MINIMUM*

Enjoy spending 10 grand on a setup that might get you two decent plants.

No thanks.

check the proycon it has 5 watt bulbs and doesnt cost the earth there are also 10 and 15 watt bulbs out there and these are great for a low yield

for fucks sake.

people read my posts before you start posting your life story about LEDS.

I don't care. This is my grow journal. If you are going to flame it, take it elsewhere on the 3,000 other posts about LEDs.

KaliKitsune, i'm glad you don't think LEDs are viable. I'm not marketing them, i know what i got myself into when i bought them. I'm NOT trying to grow cannabis for resale, but for my own personal use. I'm not concerned with the quantity of buds i will get. I just want to maximize what i can achieve with my lighting.

I'm not doing a full LED grow, my lighting will be supplemented with either 1 70 watt HPS, and a few 2-4 CFLs. To cover other spectrum's etc.

I rather be growing with an LED and a few supplemental lights, than not grow at all.

I hope this ends any confusion.

Lil1987. If you are going to post misleading information on my grow journal, please refrain from doing so. The procyon uses 56 xcree ~1.8w Led bulbs. Something like that. I'm too lazy to look up the exact details. The LightBlaze 400 uses the same/similar LEDs.

There is this website, Lumigrow that actually produce a ~260 watt LED light that uses 50, 5 watt Philips Luxeon LEDs, supposedly "the highest flux led" however i'm sure this is always subjective to new incoming technology. These are around ~$1300-1600. I have never used one, nor seen one used. They claim its equiv to a 1000 watt HPS. Who knows, nor do i care...i'm not about to dish that much for lights.

I'm trying to maintain a :

serious/professional/academic/scholastic/scientific/experimental

tone in my grow journal.


If you have questions, complaints, criticisms, rude, or naive remarks,

please start your own thread expressing these concerns.

i repeat...

DO NOT use my journal as grounds to facilitate your own debates.

DO NOT post misleading information, because i don't have the patience to correct, argue, and deal with most issues that i am already aware of.

if you have any constructive criticism on how i could improve my grow without suggesting i obtain a 400-1000 watt hps....then i'm open to hearing what you have to say.

sorry carry on with your grow man

Multan, I wasn't flaming your grow. My response was to Lil1987. Perhaps I should have quoted that but that's a little late.

Hey, I know LEDs will work, as I've spent many, many years in the Horticultural Science field, running tests on all sorts of lights and lighting. But the ones that will work are generally beyond the financial means of most people.

Everything I said was in response to Lil1987. Please don't get the impression that I was trying to flame you or your journal. I use LEDs but for growing herbs, not bud.

I may be doing something very similar right now with a couple of 50w panels in a 3x3 space, for the sake of science. I think my approach is pretty much the same as yours, as I would not be experimenting otherwise. I had written a paragraphs but I just deleted them as I don't want to perpetuate any debate on the matter, also its my first post here and I'd probably get labeled as a shill when peoples LEDdar goes off. lol. Good luck with your experiments!

im a noob to leds, but are they good enough to grow nice plant? i just bought one and now im worried. i only bought it because of the heat and space issue thanks
