ya i still have the other light its a hydro grow 126w. i was using it on two of my plants, but took it out of the grow area and but the 180w over all four girls. the 180w will cover all 4 plenty so why wast the extra watts.
humidity is real low 20-30%. i havent seen any more spider mites yet? they realy but a hurting on my plants, i will lose some yeild and barly limp across the finish line. i hope they make it, they are way stress out.
i will let u know for sure when i do my next grow:thumbsup: and ill be going to the TOWN for my next clones so ill hit u up and will put one in the air:jointsmile:
if your up in this area clones I have;
trainwreck
91 chemdawg
og bannana kush
purple diesel
candy purple
[email protected]
(in no way am i tying to sell anything, we will smoke a joint take some clones!)
good looking out bro:thumbsup: when i am in that area ill take u up on that offer. thanks!
last nite i harvest my plants. i took some befor and after pics. i wont be on hear for a few days but i will take pics of the weight once their dry in about a week
here some more pics
and some more
Good job brah! :cool:
Weeze
thanks:thumbsup:Quote:

Also, your sativa dominant strains imo are more suited to the much warmer temps in your set-up as opposed to a pure indica strain that would prefer cooler temps and may show much more stress at temps of 90+.
What was the average height you kept the LED light(s) over the plants during flowering?
Definitely interested in knowing your total dry yield.
Spider mites also as you probably know, will reproduce at an astounding rate at your higher temps, this is easily kept in check when temps are in the 75 - 78 F range..I forget the exact multiple but I think they replicate at like 5x the "normal" rate at temps over 90F...
Nice grow, good luck. :rastasmoke:
potofgold, beautiful grow my friend! A buddy of mind has some LED grow's going, and while his bud has not looked like much, I have never had a cleaner, smoother high, or a better taste. Your buds look amazing, as good as anything I have grown under 1000w HPS. The trichrome's all look very bright, smooth, and milky! Nice work mate! I am thinking of setting up an LED grow in a Sun Hut type space, due to living in a 1 BR apartment now. I will keep checking this post, I am interested in what your harvest weights are! :thumbsup:
good looking harvest POG! i plan on getting (or building) some LED lights in the future. always so much to do and so little time and money!
-shake
i harvested a little over 3.5 ounches dry. but i only got about 2.5 onches that were smokeable. when i can home and checked on my buds the spider mites web up alot of my buds. i took a big hit because of those little fu$kers. the shivias where able to ripen barley, but the super skunks were premature buds. i wont even smoke them because their so $hity. i will probley toss them out. the shivas were nice and dense and are some killer buds. they got me super high befor i even cured them. right now their in the jars curing.
so the high temps i had and those mites fu%ked me and my grow. the mites also web up my fat tops so those got threw out. man i didnt even get the chance to smoke my tops! i am realy pissed that those mites messed up my plants so bad. and the high temps just made them hatch faster.
i hade no chance but to pull my plants eirly, they just werent growing anymore and i couldnt get them to finish i spent 3 or 4 weeks trying to let them finished, then i relized i would take my loss and not wast more time i could spend bombing those mites for my next grow can start.
you can belive its war on those mites now. i have three differnt bombs, a no pest stripe, and some watered down bleach for the walls. for the next few weeks their will be war in my grow room. once i get this all tooken care of i will get me some more clones and start that led test between the 180w vs. 126w.
I highly recommend introducing ladybugs in your next garden to take care of those terrible little spidermite bastards...they are extremely ferocious predators those pretty little ladybugs and they will tear the shit out of some mites for real. You can order them online from like lowes or home depot..they're cheap and alot of people use them in their outside gardens so it's not really something you have to be worried about getting delivered to you. Plus they are cool to watch when you get high hahah :hippy:
right, i got my clones for this led test, heres the link. i wont be posting too much on this thread since its an old one. ill be on this new one from now on

Now you are just pulling numbers and theory out of your ass. The sun puts out 30k lumens, cmon now. Per what, square inch, square foot, square mile, what?
Maybe it's heat burning the tops of your girls? 95 degrees has the capability to do that, especially if your canopy temp is higher. Why do you think mylar blankets are used for emergencies? The reflective side has the ability to reflect heat also, thus keeping us warm inside them. Maybe that's why the edges are browned too?
This is my problem with this claim of "light burn". The only time I hear people complain of it is when there are 3 other variables in their grow that are fucked up. It's never on a dialed in healthy grow that someone gets "light burn", or "light lockout" or any light issues for that matter. It sounds to me like many cases of poor troubleshooting.
Most is, some is not.:cool:Quote:

I think it's about 91k LUX m2 of full spectrum light.
Above that bleaching does occur, just not with UFos.
I was unable to bleach tops with the 2 UFos that I helped folks with. the 1W. diodes don't have enough "juice" but the cheap ones will cause heat burn at about 1/2".
And no, they are not "brighter than sunlight".
The are just a hell of a lot closer than the sun.:cool:
Read, brah, read.
The Growing Edge Magazine - Rays of Life
Good info on the saturation point.
No accept dat?
Fine. jus' google "light saturation point" and get comfy.
Did not like da smell of dat 30klux comment.
We know where you got it from :S3:.:D
Aloha,
Weezard
At least I can wrap my head around that, and get an explanation from someone who has experienced it. Friggin sheep are all gone bro...
Less Bah, more humbug.:DQuote:

1st hand "experience" is often marred by the conclusions drawn when one lacks key information .
So, I'll be off reading for a while.:)
Aloha nui,

Whats up guys...
First of all.. Every grow ive used my 90w ufo on... wether it was primary light or sidelighting... I always get what I guess can be called light burn. The fan leaves directly under the UFO brown up and die. This only happens when I have it close. 3-4" I would guess..
Its not heat or anything else. Ive even posted about it before but had no replies.
Oh and weezard... ive bleached my tops with my 90w UFO. Got pics too! The UFO was several inches above the tops and it still bleached.
:stoned:
I'm not trying to dispute the fact that it's done, I too have seen the effects in others grow logs. It may have some thing to do with strain as well (doesn't everything). I only say this because I just had a fully mature Church plant that was harvested under 150w of 3w diodes, and no ill effects whatsoever. The tip of the cola was about 2" away from the LED panel.
I obviously have some hardcore reading to do, I'm not claiming at all to be educated when it comes to this topic. I can only speak of my own experience, and out of the dozen or so strains I have had my hands on, light has never had an ill effect, HPS, MH, or LED.
I'm wondering if this may manifest itself as a combination of issues, maybe an underfed plant would be more prone because of metabolism being slowed from little food. Something to that effect. Speculation at best, but I'm off to do some research. Hopefully I'll find something interesting.

its real simple iridum get you a lumes meter and the sunnest day go out side and test it your self . bought mine off ebay. 95 is at the canapy why would i give you temps at the roots ? weezard is right 91k max and even then my girls feel it. now go and grow your own to find out and if your not willing to take what the growers that have did the expermentings word then why are you even asking.
If you don't think mylar reflects heat you are ignoring fact.
Lumens is not how plants see light, you would need a PAR meter to get a reading of what your plant sees as photosynthetic energy. That's plainly spelled out in the link Weez provided, did you by chance read it?
Weezard shut me up already. I can't argue that "light burn" or "bleaching" happens when he posted a picture for proof. Nor am I trying to. I'm saying that if people are having an issue with their plants processing artificial light, that it probably is a combination of things rather than just too much light.
Notice how Weez thought it peculiar right away when he read the symptoms of this guys problem? Likely not from too much light, at least not on it's own. From everything I have seen and read it turns leaves white in spots. It doesn't fry them off like nute or heat burn.
Let me say again, I'm not arguing with the principle of a saturation point for light in plants. I just don't feel it's should be an accepted diagnosis until everything else is ruled out. I have seen quite a few people talking about this, but the only really good example of it I have come across on here is the one Weez just put up. Most of the others don't look like that. Hell I've even seen someone recently post they overlit their plant with CFL. I didn't post there because it seemed ludicrous to me. You all seemed a much better bunch to hash it over with.
Well weez... They get like crispy amd damaged. But only the ones directly under the LED light. I will have to wait until tonight when my lights turn back on to get a pic of the damage BUT i do have the pics of bleaching buds from the UFO.
Also have another pic I found on here from someones scrog grow that got bleached... looks crazy so I saved it.
:stoned:
pic 1 - someones bleached scrog
pic 2 - closeup of one of my bleached UFO buds.
pic 3 - is the two buds that got bleached. They were the two closest to the ufo.. maybe 5" away. It wasnt that close at all which surprised me. I had no idea what it was until I did some research.
Thats also an interesting theory Iry... about there maybe being underlying causes for the bleaching or "uv damage" like an under fed plant... must do more reading but my eyes hurt.

You'll note that the demarcation is sharp and well defined.
Light bleach has a more gradual transition and it usually affects the leaf surface as well as the bud tips.
That may be heat related, which is after all, just another form of EMR.
Longer wavelength, less energetic, but EMR all da same.
Heat rises, and still air can create thermoclines indoors.
There may be a temperature tipping point where chlorophyll can no longer be synthesized.
That is my best guess, but I do not actually know.:(

Good call Irydyum.
Find anything yet?
I came up with a very odd effect that occurs on lower leaf as well.
Can't find da picture but it looks like a genetic hiccup in chlorophyll production.
Half the leaf appears normal and the rest is normal, but colorless, almost snow-white.
The transition is abrupt. And the demarcation is straight line and razor sharp.
I'll see if I can dig up da picture.
Dang! I hate not knowing.
He'p! Somebody, he'p!

I can find lots of papers on Photosynthetic Saturation, Photosynthetic Rates, and many others as they relate to c3 plants. I spent an hour or so yesterday reading them, unfortunately I didn't bookmark them, I'll be looking again today.
The only common theme I can find so far, (that I can deduce from papers written with university speak) is that there are many factors which calculate into what would be considered the saturation point for light in a given plant species. Among them are the things which all cultivators are familiar with. Food, CO2, and Water. The levels of all 3 seem to play a part along with genetics in determining how much photosynthesis can take place.
I can't find much citing specific examples of damage resulting from the oversaturation, most simply seem to claim that it is a point of diminishing return. One abstract did point to oxidation as a culprit for damage, but I didn't really understand the science behind it.
I'm still hunting:rambohead:
BTW Weez, I have seen what you describe with the razor sharp demaceration line as well. I saw it in person on one of Headshake's plants from a past grow. I know he has pics of it too, so I'll see if I can find some. At that point everyone attributed it to genetics, claiming albinoism. That leaf stayed intact for quite some time too from what I remember.
