LED Grow

[jubiare]

I cant say that its a fact, but my months of research have led me to believe that with the right LED configuration resin production and overall product quality can be achieved over conventional lighting. It may be that yields, under otherwise comparable conditions, tend to be lower than HID, but the bud will be frostier. I also believe that the addition of UV light can help to achieve this same effect. And as I'm sure you have noticed from the specs of the light you are now running you have added some UV to the mix. Again, I dont want to put it out there that these things are true, its just what my months of research have led me to believe. I also think that my addition of halogen has been beneficial due to its high "red" output and infra-red (something you are also running a little of on that LED). It also happens that I have no heat running to the grow room and running a 150 watt halogen and getting some light out of it makes more sense to me than running a 1000 or 750 watt space heater during on cycles, as I would have to do otherwise. It warms the room to just the temp needed. It may be against conventional wisdom that a halogen is a good grow light, but I have never given a rat's ass about conventional wisdom, I just want what works best. Plus, it was free just laying around the house. It was my first addition after flouros-- and when I put it in the plants woke right up and started growing. I think they like the mix of light they are getting now and the buds are dense, unlike what some experts say about LED lighting.

I can only agree and confirm, that with halogen you archive having far-reds (missing on most leds panels) and low temperature issues

Well, something is being done right.

Damn those plants are beautiful when do you think harvest time will be?

Well, all I can say is that each plant has different genetics and will have to be treated individually. Today is week 7 of 12/12. One of the two that I topped has twin colas that have a large % of amber pistols and they seem to have almost stopped growing, while the lower buds continue to enlarge. I will probably remove those colas in one week, allowing the rest of the buds to bulk up when it loses apical dominance. The others are anyone's guess.

Sweet I haven't seen a plant in flower yet so I'm excited to see what my plants will look like the tops are changing on them right now and they have white pistils everywhere on the stem lol its pretty cool looking.

The plants side growth is shooting up alot now you can barely see the stem

Subbd.

Your plant is doing some serious growing. That light seems to be doing a great job. I was curious on how good that HTG light was. So far its proving itself.

I have more pictures to upload when i get home my plants look even better

Thats right, Im subbed on this too because I want to see how the light does. I have the same configuration, though its the 135 watt model. I did all this research on LED, but then bought one I really couldnt find a journal or anything on. But I liked it from the time I got it home and plugged it in 7 weeks ago though. Still, I want to see how someone else it doing with it too. Like mine after I set it up, his plants are looking good. The only thing I question at this point is how much good the light is doing beyond, say about 30" or so. Wish I had a par or lux meter, but I dont-- and wont be getting one anytime soon. I want to stick with LED, because I will be having heat issues this summer, even without a blazing hot 600 watt HID. What I question right now is should I stick with this/Black Star style configuration or should I dump the money into lets say... a Lumigrow LED? Also, I plan on going with a shorter auto flower strain grow after next, so it may not make much difference anyway. Still, I am impressed with Lumigrow's sales pitch. But thats some heavy bread to be laying out for a light.

I was skeptical when i first bought my htg light because i couldnt find anything on the forums about them but i got it anyway. So i guess i'll be one of the first to document a grow with this light and so far its doing wonders for my plants i am extremely happy with this light so far!

 

[MIMA]

Heres plant A she looks real good and we tied the bottom bud sites down so they can get more light

Heres plant B shes still a little behind

 

[BenRound]

MIMA, tight bro. As in tight inter-nodal spacing. I love it. How far from the canopy are you keeping that LED?

 

[MIMA]

Right around 8 inches away. I like the tight node spacing too it was done completley by accident though haha we didnt know how far away to keep the LED but i think this might be perfect because we have less space to cover with the light so it seems like it would increase yeild i may be wrong though

nice pics, are those cfls in the attached?

 

[MIMA]

What do you mean? Lol

Still trying to work on a way to take a pic that shows the true frostiness of the bud. Seems like any pic I take is just a pale reflection of what it looks like in the real. But anyway, I think you'll be happy enough with the light MIMA. Then again, maybe the denseness of my buds is related to my rather unique light mix. In any case, I figure your buds should frost up nice under that light. Cant wait to see how they turn out under it and CFL, because come summertime that will likely be my mix of light too. If yours turn out nice I may get a 240 like you have to add to my 135.

wow! those buds are looking good man your gonna have some real good smoke. and if your concerned about heat i'd go with the led over cfl's the cfls are way hotter than the led. around what week of flowering did you really start seeing bud growing on your plants?

They indicated sex depending on genotype. My favorite, that luckily I made a successful cutting from, sexed in within 48 hrs of 12/12. Its a hardy plant that shot up long stems that compete mightily with the twin main colas I made from topping. Its frosted goodness appeared quite early and prompted me to dub it "Frosted Flake". I hope to keep this genotype going and perhaps cross it to create a new strain. Another type took 7 days. And lastly another took 12-14 days. I noticed the ones that seemed predominately sativa sexed earlier and the predom. indica last. I dont know if that is a normal trait or even if it means anything, just something I noticed.
So... to answer your question between 10 days and 3 weeks there was something on a plant I would call a "bud", depending.

Just subscribed! Im on my first LED grow too. Im so happy to see that someone else is using HTG LEDs. So you can put them that close? Mine are about 2+ feet away from my tops... Im gunna change that tonight. Right now Im using 3x240w 7-band, 1x135w 7-band UFO, and a 120w tri-band. I'll upload some pics. Got some powder mold on the younger ones so theyre still healing. Nice job so far

Wow, another person using these 7-band HTGs--- cool.

I wish I could throw you some specs on the optimum spacing on these lights. Thats why I asked MIMA how high he had them set. I wish HTG would produce some specs on distance etc. If they have, I couldnt tell you where they might be found. Maybe we should call them and ask.
I cant really say for sure, but I took a stab at guessing the optimum distance before I set my light up. Based on my previous research on LEDs, the output of these lights etc, I came up with 12" above the canopy. I have had it as close as 2" with no noticeable harm done. I really dont think that its doing much after 30" of travel (like to the bottom stems), thats one reason Im thinking of changing strains for my next grow. I also think anything closer than 12" doesnt give the light much spread for my purposes either.--- If any of this helps.

Maybe between the 3 of us on this thread using these lights we can get a PAR meter, get some readings and/or ask HTG for some research specs on these lights.
