^^^^^^^^^^^^I suppose it could be from heat stress after hitting 101 F for a couple hours the other day? The temps haven't been breaching 90 F. I'm going to install longer water chiller feed tubing today to get the added heat out of the room. Pretty damn stupid to put the chiller in the room to begin with. I guess I thought it wouldn't produce that much damn heat.

Live and learn I guess. Could we please get this thread more active? What should I do to get this place rolling?

how exactly are they rolling down? like brown edge rolled down or green leaf rolled down? slight roll? or straight drop into limpness?

pulling the trigger in these x3 2x4 tents today got them priced here at 76$ea. plus 5$ shipping for all of them,

my issues im only gonna be using 2 of the tents right now the 3rd is for later or after i move when this lease is up, what lights should i run in each?
what i have, x5 2tube t12, x1 2tube 54w t5, x1 mag. 400w hps ballast, x1 mag 400w halide ballast, 400w lumatek, 6 tube t5, and umm a solar glo MV but that goes wherever the flowers are.

just so many options but im trying to be as electric efficient as possible and yet still retain full spectrum, my current setup with about 1000w of light in a 3x5 is a little wastful IMO and brought about heat problems occasionally.

i wouldn mind buying a 4 bulb t5 but i have yet to find one cheap and im also indecided on whether or not i should buy the 3rd tent i just dont want to run into any males or fems this last grow around that i would like to get more seed from and not have a place for them.

heat stress that what i was gonna say if its brown edges it heat stress as the plant literally pulls the water from the edges of the leaves.

Found this on Rive's thread over at ic. It validates the need for green, with one important caveat that I think has bee missing from various threads/conversations/discussions both here (RIU) and elsewhere- other grow sites

Actually, recent studies show that plants do use green light. This utilization only kicks in when the blue and red have hit saturation levels.

I suppose saturation level means the same as "high irradiance" level. All of these crazy hi-tech terms gets me confused sometimes. I guess we gotta just remember that it's easy to understand once we can put it all into basic english! LOL

I'm having some really good things happen right now in one of my test boxes. My MAIN grow box is giving me hella trouble. I stuck the 1000w MH 3K Sunpulse back in with the 4 x h150 red Kessil that I've always used for flower. These high temps are what's really screwing with the plants right now. I don't even know why I bother growing in the summer. I figured the water chiller would solve my problems, but I can't use CO2 because as soon as I close the door, everything start condensing like mad.

2 hours later, there is a 1/2" puddle of water on the floor, electrical short waiting to happen in there.

Poly, the leaves are not brown at all. They are green but rolled down like a rolling paper lengthwise. I don't know if it's heat stress or a spectrum issue yet. All the other strains are doing fine. It's only happening to the Lemon Skunk. That strain is so picky and hard to clone.

thats sounds like heat stress to me move the plant out of direct light it should perk back up if you leave it it will develop the brown leathery leaf edges. but it does seem odd for a skunk to be getting heat stressed although a freind grew lemon haze and it was a difficult one, not only the fact it strectched like crazy but didnt do well in diect light, bluecheese is a strain thats not much for direct light either.

Here's something to chew on. The argument started AFTER the grower Inefectualize got 5.7 ozs using only 4100s

I think Infect got such good results with 4100K bulbs because if you truly know about indoor growing plants only need a tiny bit of Red light because the use red very efficiently since they only receive a little bit of it from the sun and look how well outdoor plants do... Bombarding plants with red light is actually kinda retarded when it's the rest of the spectrum they need a lot of to grow proper but everyone just see's HPS being used so thats what they go with and how are we ever going to progress if everyone does the same thing?? Look at me and DrBud we break all the so called rules of cannabis growing.... My buddy's Horticulture Teacher says "nothing is impossible with horticulture" So I like to keep a open mind shit even Jorge Cervantes say's "an expert grower learns something new every grow"

KNNA chimed in Kudos for sharing it. I saw the final pics you posted on another thread, but i didnt know this journal. Really excellent.

I cant understand some critics about the lighting. For me is clear that it works, and works very well. Yes, i get slightly better results using 827 tone (triphosphor 2700K), but difference with 4100K (840) is small. Both are balanced spectrums and gives a similar amount of photons per watt burned, which is the main parameter about lighting. Spectrum distribution, as far as its balanced, affects g/uE (Light Use Efficiency, LUE) only slightly. People tend to overweight spectrums, but in real grows they often makes little difference.

A bad spectrum may severely hurts final yields. But most standard fluorescents do it well, and very often, better than "horticultural" bulbs, which usually emits less photons per watt. Very often lacking of light on the green/yellow range is reducing yields and LUE, as seen on many red/blue LEDs threads.

But the important is PLLs gives more light per watt than any other CFLs, and thats the most important. On small spaces as this case, they give off the best yields, very often better than the small HID alternative.

What is PLLs? I wouldn't disagree that Neutral Whites are going to do a good job start to finish. They are a great choice for a full spectrum light source. In fact, one of the best grows I've ever seen utilizes the neutral white cree 3w and equal amount of red led/deep red. Outstanding results, best I've ever seen, and just because the Sun does not emit red light in high quantities does not mean that it's a bad thing. In fact, the Sun can be very damaging to plants in general. My best grows have been indoors. It also depends a lot on location. For someone that lives in the North, like me, I only have about 3 months where I can grow absolutely anything outside. The sun is so intense during those 3 months that it's hard to get anything to grow well. The spectrum is very blue here. Cannabis is one of those plants that do not grow well outside at this latitude.

My indoor grows have only benefited with the added red/deep red. It has kept my plants shorter, healthier, and has made the buds much denser and flavorful. I'm not sure this guy knows exactly what he's talking about, although I do agree that red/blue combinations are lacking. I would also agree that people who are going to excel at whatever they are doing will be open to change and new ideas.

I just don't think that we need to flop back in the opposite extreme. I've got at least one good spectrum that is doing better than any other spectrum including any 1000w HID lamp, or anything grown under the Sun in my local. I will not release this spectrum until I can get a SPD made for it.

I just purchased a spectrometer today with the rest of my cash. I'm literally broke as of today. Should be a pretty useful device. It's going to help quite a bit to develop my LED spectrum. I will be going of a MH/LED combination that has been working wonders for me lately.

I'm running 8 lamps,3 flora suns,2 aqua suns,2coral waves and a red sun.
I was thinking it was slightly more to the blue with these but I think now
it's pretty balanced blue to red.
It looks around 40% blue,20% green-yellow and 40% red,have I got that about right?

Could work. Watch how your plants respond over the next few days. I can usually see a good response happen over night, sometimes sooner depending on how much the plants likey.

Are you vegging or flowering under this spectrum? If this is for flowering, it seems like you would want a bit more red or orange-red to shift the spectrum, if it's for veg then just keep an eye on the new growth. If they are perky, the leaves have a "V" shape to them and are reaching for the light, then you got it.

Always try to keep the floro's close to the canopy for optimal growth.

4 - 5" tall clones just transplanted into large pots yesterday,2 days under these lights.Ive got some speckled yellowing on the outer edges of some leaves and a few brown tips. I think they're hungry,my nutrients will arrive in the mail this morning.Hope I don't lose power,a very severe thunder storm is about to hit.

That's a lot of light for small clones. Run 2 bulbs and see what happens. First try 1 AS + 1 FS
Ok,I turned off half the unit.Now has 2 flora suns,1 aqua sun and 1 coral wave so it now has a little more blue.
Their in 5.2 gal air pots and 14" from the tops to the lamps.

I run an 8 lamp fixture over my seedlings and cuttings. The lamp is only 10" with all the lamps on and I've never had any problems. The more light the better. They will just stretch a lot less and get beefier stems if you have more light from the get go.

Yellowing on the edges does not mean they need food. Brown tips are a sign of over fertilization. What are they in right now? It could be a PH issue. It also could be that they are still clones and it's just stress.

Wait a sec, they are in 5 gallon pots already?!?!?! If they are just clones and they are already in 5 gallon pots, you may have a problem. I have NEVER had good luck putting tiny plants into large containers. The roots get "lost" in the pot and can't find the bottom. It's most likely the fact that with tiny little roots, they will not get enough oxygen and the roots will also just rot right off since the amount of water they will have to get through to grow.

It's really best to start out with a small container, then transplant up as you go. I would transplant to a 3" x 3" container depending on plant size. Could you post some photos please?

Well, bad fuckin news guys. The leaves are curled due to another thrip infestation. I think I caught it early enough this time that I nice dose of Monterey should do the trick. I can't believe I even started over from cuttings and those fuckers still managed to find a way back in. I'm sure it's because it's summer, and stupid fucking bugs are finding a way in through the cracks of my house and bringing in the thrips with them. I keep finding beetles and different flying bugs from outside invading my grow space.

I HATE BUGS!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I sprayed all my plants, cuttings, and seedlings with a light dose of GoGnats cedar oil spray. The shit is pretty dangerous to plants and I have had some issues using it before, but I want to "hit" the thrips to at least keep them from multiplying until the Monterey Garden Spray gets here.

Sure has been a rough Summer, damn bugs need to GTFO!!!!!!!!!! Fuck you bugs!!!!!!!!

They're like 2 weeks old and in 5.2 gal super root air pots which should give them plenty of oxygen.I took them out of 3x3's and put them in the large pots so I could start LST'ing them,I have a height issue for their space.
The soil is a even mix of foxfarm original,ocean and happy frog with some perlite added. I've been ph testing the ro water I use and they haven't been given any fertilizer since I got them 3 days ago,and I'm pretty sure I haven't over watered. My friend who gave them to me said he had already started feeding them. Only camera I have is the crappy one on my phone and that would be a waste of time.

New news on the blue spectrum. In led section franjan started a thread about melatonin in plants. Specific nm's of blue light which supresses melatonin levels. Can account for cal mag issues and yield. This is just debate for now. Even in the scientific community.

Any idea what NM they are debating about?
