Be careful not to knock it unless you know what you're talking about... here are a couple of articles on UVB light & IR light that may be helpful:

FWIW: I will easily pull 2-3 zips from 100~ watts actual consumption, so I'll go ahead and disagree with your vague blanket statement. That is with no top/fim/scrog/c02 or any other methods and on my first hydro grow, having made tons of mistakes along the way. Comments like this add absolutely no value to this journal or anyone reading it, so post them in general discussion or anywhere but here in the future.

In other news...I selected the best double gum & mango phenotypes and killed off the others. Here are some pics of one of them today while I was transplanting.

I can not say I know exactly what im talking about as I'm sure the science behind it all is very complicated. But I have the jist of it.

Sun gives UV, marijuana 'developed' thc to protect it from UV, therefore more UV = more bud. Or so it goes.

The first article by Ed Rosenthal has many spelling mistakes which make me doubt it to start with. I know its probably been copied but still. On top of that the only comment about UV increasing yeilds is this quote:

"UVB light also affects marijuana potency. The potency of high quality marijuana increases in direct ratio to the amount of UVB light it receives. This is very significant. In California, where the medical dispensaries operate in an unrestricted market, many dispensaries reject fall-harvested outdoor material, deeming it as inferior. They have found it lacks the potency of indoor crops and is a harsh smoke."

All he does is make a statement with no proof or explanation at all. Later he mentions testing with different light spectrums and says he this:

"Try using between 20 and 40 watts of mixed blue light per 1000 watts of regular light. I have done only initial experimentation with this so test this in a limited way of increasing total yield."

Which is again very vague and tbh pritty stupid. 40 watts of blue ain't going do shit with 1000w of HPS there.

The second article is just him saying they are experimenting with different lights. Again that doesnt mean shit.

And the key point, how much do those lights cost? How many harvests do you need to break even on buying one of those, including the savings in electricity. Compare this to a HPS and bingo you have a very obvious solution.

To 206, sorry that was a pritty lame statement i made but ive been watching this for a while out of curiosity and i see all these people talking in here with their false hope for this magical new technology which creates wonder buds.

Not to be a complete douche but have you actually harvested 2-3 zips from this 100w light?

How big is the plant which produces 2-3 ounce of buds?

How long did it take from start to flowering with one of those?

I dunno, man.. I've been following this thread from the beginning. I'm very impressed with its vegetative growth, at the very least. The buds do seem very popcorny, at this stage, but they're sizeable and they seem to be fusing a bit more over time. I'm confident, personally. The one thing that too many people fail to see is that people will design their grow around their environment. Someone who doesn't have a spare closet or any space to put up a "legit" grow box will choose a PC case. Someone who is very concerned about the environment might choose an LED or CFL. Me, personally, I doubt I'd go HPS any time soon. Would I like to? Sure. I just don't want to deal with the intense heat and I don't feel like spending all that money on it when CFL's work very well these days. I think a combination of CFL and LED would be really winning, which is exactly why I've tuned into this thread for so long.

Also.. all of the answers to your questions are in this journal. Maybe start at the beginning and read the whole thing before passing judgement on a new technology? And the money on LED's isn't too bad anymore. Growl LED is affordable and decent, from what I hear and the UFO is supposed to be the absolute bomb. I dunno.. to me, a $300 LED, if it can be close to viable, is so much cooler than HPS, if nothing else, for the environmental factor. All that wattage for HPS!! Do you get QP top colas? Sure. For those of us who don't require an assload of pot for personal use, though.. LED, CFL.. both very viable, in my book. I bet these Papaya nugs smoke great, too. I hope 206 kicks back thinkin' about all the fossil fuels he saved by going LED while he blazes that first pipe.

This thread has been going since November. I have been here since nearly the start but I'm also subscribed to many others threads. The point is I don't have perfect recall and will be fucked if I'm going to sift through 21 pages to try and find answers to questions I probably already know the answers to.

But of course none of this matters if we are going to melt the poler ice caps and drown in a flood of our own stupidity.

HAHAHAH!!! Funny stuff, man. +rep.

Thanks for "getting it" ElephantRider. With all that HID yield, I'm suprised this guy can't smoke enough weed to not be a complete downer.

Anyways, I'm going to follow repvip's lead and stop feeding the trolls now. If anyone wants to see updated pics going forward just send me a PM.

Wait.. you're shutting the thread down? Ugh!

I gotta see harvest pics still!

Woah Woah, hold up there brotha.. You need to continue this thread. First of all you got me interested enough to even begin learning about this technology. Prior to LED's growing was'nt even close to being an option for me becides CFLS. This retard has no idea what he is talking about.. Kindly follow this link to see new LED tech and real experiments to test it www.greenpinelane.com .LED's are the furture.. but not even that they are NOW.. the slower these morons are to get on the ship the more money they waste on 90% Heat loss, and venting that peice of shit light out of their room.. Dude your plant looks great and the retards that stop by and talk crap are just angry.. LED tech is already amazing and it is slowing upgrading. Within 4 years HPS lights will be laughed at because they are completly impractical. Keep your thread up dude, your not alone. Soon i will be starting my journal with the same 120W Triband LED, a 90W Led , 50W panel , UVB CFL Light, and an infared light to use right after *lights out*.. Did you read that article 206? Its freeking crazy shit,,, this retard is too ignorent to see past grammer when we are talking about ground breaking technology.

i agree i am a 2 x 1000watt in my bloom ...so i am hid all the way ...but 206 you have gotten me interested in led also


i see the veg application of led is immense

the only time i do get efficienctcy is in winter when i can vent my hoods inside and actually heat the house while growin with lights

other than that tho i waste alot of energy in the form of heat ....energy is in many diff forms and with no venting ...well it makes some sense ..... ....wouldnt that be sick if they made like huge ass led bulbs .....maybe taht is what is next ....

i know this led flashlights are so much better with energy and light ..so i know that is an incadacent bulb but ...i mean cmon i think we should give led a chance ..

206 +rep if it will let me give you some

Sorry, I frequent green pine lane, and no, LEDs are not even CLOSE. Not when we have T5HO bulbs that are pure red and pure blue, now!

See, LEDs are very focused. In order to hit EVERY photosynthetic peak, you need six different wavelengths of LED. A single red and a single blue T5HO lamp will cover those ranges, and they output mad light, plus have more canopy penetration thanks to the intensity.

I do agree with not shutting this journal down, people need to see the pictures, final harvest, all that good stuff. I rarely see any complete LED grow journals (and those that never finish should be deleted, IMHO, to save on server resources.)

i love t5 HO lights .....i use to think they were crap till i started usin a regular set of flouros for vegg purposes and notice way good results .....even better than the 400 watt metal halide i had ....because sometimes my plants just dint need that much light at that particular phase of their life ......

so i decided to get a t5 HO light ....they are so cool

u use a rainforest like me too right 206 so that means this thread will be even more beneficial for me

o and i tell you what 206 my plants never took to bloomin good in the rainforest for some odd reason

it is a monster veg machine tho

I love whomever gave me the positive rep but stated "Outdated LED info--get current or stop posting about it." I know it was meant to be negative rep.

My information is quite current, possibly moreso than whomever gave me this rep. I got to see Primary Color T5HO in action, and I've seen plenty 3rd gen UFOs as well, all at the same hydro shop. I've seen custom-built LUMILED panels using 10w LED bulbs, they STILL don't beat out the T5HO Primary color tubes.

This is just a first time LED grow to test the strength of the LED's and its clear they are powerful for veg and its also clear they need some help during flowering. Who knows how LED's would work with c02, more ventilation , different nuets.. i mean there a 1000 possiblities and not many grows to show success compared to the shear mass of people using HID's .. Also this grow isnt over yet.. im interested to see how much is yeilded and what it looks like at finish time. Atleast keep posting a weekly few pics if you would 206

These tubes you are talking about.. Not that lumens matter in LED lighting but what kind of Lumens are you getting on your tubes.. i guess these are flourescent tubes your talking about? .. Have you tested a UVB bulb or this apparent spraying of UV light to activate the flowering fase quicker?

Who knows how good LED may actually be with a bit of tweaking, remember it is relativly new for growing in this manner, for this plant.

Sorry not spraying UV light... Infared light i mean

The fluorescent tubes vary depending on length but the T5HO GREEN 4 ft ones pump 4400 lumens, no filters, just special phosphors to emit green light. Not much in the way of IR emissions but there are some UV emissions that are just due to the nature of the bulb.

Wait green light? What the heck is that usefull for becides looking at your plants at night. And by the way LED greens are much simplier and more pure. They have Green LED light Hats to check on your crop during the dark cycle lol

i myself never used flouros for bloomin but my t5 HO i think is suppose to have like 5000 .....i may be wrong i dont even feel like lookin ...lol i know it is alot higher lumens than normal flouros

o and i never used for bloom like i said ...but for veg purposes i have found flouros to be the key ......

see i use to try to use my 400 watt to get clones just rooted and such to get started ....i found that usin flouros i actually made more space available for veggin ...

mainly flouros i think are great for vegg purposes ..

but light penetration of HID is a nice thing to see

i think led might be the next thing tho .....at tthe very least for vegg purpose ...they are just so efficient

soon they will prlly perfect somethin new ............

hey let this bake your brain ....what if they came up with a way to blast the plants with lasers ......super intense light right ........never know whats gonna happen with tech

"the only true knowledge is knowing you know nothing at all"
