LED Without LEDs -My First T5 Grow

I thought the whole purpose of this thread was to optimize plant growth and potency through tailoring your spectral outputs for your plants, I think it's reasonable to assume some strains will perform better than others under certain lighting conditions. If you are looking for a single ubiquitous lighting solution you are defeating the whole point of this thread. No?

I don't know anymore. After staying up for 24 hours straight wandering down the golden path of what's right, then finding out the path splits off into 2 more directions, then 2 more, then 2 more..........smoke started to pour out of my ears and I forgot where I was going in the first place.

Weez goes way back with leds, so I tend to believe what he thinks, BUT, I think you still want ~ 20% 5-600

I'm seeing this thread getting jacked toward LEDs and that's not right. Fonz why not start a new LED thread based on WEEZES ideas? FYI I am having trouble finding his pics beyond the first one that you provided the link for

Agreed. I have no interest in LEDs, if I did I would go to that forum. This was suppose to be about T5 lighting, but apparently even the (MIA) pr0fesseur has given it up.
 
Pro pops in once in a while. I think he is just a lurker now. I got a few likes from him a few days ago.

Its funny this thread already went through the led phase before we knew about the flora suns. We all were looking at 660 supplementing with kessils or advanced led par bulbs. Then Pro popped in with new bulbs he was having made. Then that changed the direction back to flouros. Those bulbs were never made I guess.....

Its about imrproving grows with better spectrum and less watts. Led is sort of the cool cousin that you are not allowed to hang out with. I know its a cheezy metaphor. Hid is the enemy....... Incorperating t5 with led, why not if it works and improves grows....? Just do not leave the flouros behind. Because of us, we got uvl to make the 660............ Dun dun dunnnnn

Enough of my ramblings.

Happy gardening people

We are using T5's. Light is light, and with all the wavelength/spectrum information that people are doling out in the LED industry it's a nice resource to use when figuring out a T5 setup. At least try to read a few pages before making annoying judgements lol. The name of the thread does have the word LED in it so I can't imagine discussing or comparing LEDs to T5s would against any rules. I guess I really don't get what your point is though.
 
AMEN to PF for making the lamp development at UVL happen. That type of shit doesn't happen very often ya know. I haven't even seen anyone thank PF for doing it. So THANK YOU PF!

I'm going to give your theory a try PF. I popped in new arrangement of T5's in another fixture. I think I have about 6 individual light tests going on with constant environmental variables at each station. The new fixture has from left to right, 1 UVL 75/25 for the violet/indigo/green/orange, 1 UVL 660, 1 TrueLumen 460, 1 UVL Red Sun. Yeah you heard me, I'm giving the Red Suns another chance. I even set up the light fixture with the red/blue counterparts of Chlorophyll A and B right next to each other so booooyaaaa, it's gonna work even betta now! hahaha

It's really putting out a nice magenta/pink/orange color that "looks" like it's going to work well.

In case a few of you are confused, I am running 4 lamp fixtures instead of 8 or 10 or 16 lamp fixtures and am trying to get better results by using either 4 different lamps at a 1:1:1:1 ratio or 2 different lamps at a 2:2 ratio. I think it's possible by fine tuning the spectrum as much as possible. I'm trying really hard to do without any white triband, but I do have a couple fixtures with 1 partial white lamp(UVL 75/25 or Aquablue special for example).

May be time for a new thread T5 + LEDs The Best of Both Worlds

I was not involved in lighting a fire under UVL to make the 660. I simply inquired and found they were almost ready to introduce it

His UN says it all (no offense Novice). You should know by now (based on the comment you made about finally beginning to understand what I have been saying) that the T5 info alone can be overwhelming. I have learned a lot from this thread, too. Thankfully, I never bought the Fiji, not that it's a bad light, but it costs as much as a 660

The only thing I would change is not to incorporate the 660s until mid-flower. Not because it isn't a good idea, but I am told they don't last long, and at $30 a pop, well.... I just shot Jeff an email to confirm. Keep in mind the Florosun has a decent 660 band + 500-600: I use 2 in both V&B. New pics tomorrow. All I can say coming dow the wire on blending aquarium bulbs is that I have never had such tight PHAT nuggz

I would like to see you test with 4 of those. Depending on how the plants look at mid-flower, then replace 1/4 with a 660

I have 3 Red Suns under the hood. The new ones are fine

 
Just heard back from UVL:

We are seeing useful life at 4500hrs before 25% decline in phosphor drop. At 10 hrs daily = 450 days, recommend replacing yearly.

Are they running the bulbs non stop or 20 hours a day or what? They just started making the bulbs less than 6 months ago. I have not even been doing par t5 for a year yet.

UVL started developing these 660nm lamps along side an overseas lamp manufacturer (Hungary I believe?) long before this thread even started supposedly. I think it's a pretty amazing coincidence that when PF contacted UVL they already knew about the 660nm potential. Makes you think twice about collective conscience doesn't it? LOL, anyway PF said that they were running the lamps 10 hours a day in his post so that's most likely what they've been doing. Unless of course you think they are full of shit. I highly doubt it. These lamps are top of the line and work extremely well. But please do not buy them so there are more for me!
 
Wow. It's amazing how simple math can be so confusing. UVL says We are seeing useful life at 4500hrs before 25% decline in phosphor drop. PERIOD


Take 4500 useful hours multiply by 25% decline in phosphors = 3375 hours at 100%. This means if you are using them only for flower @ 10 hrs/day you will get 337.5 days of 100% phosphor before they decline. This is why UVL says they recommend replacing yearly.

If you are running them in both veg and flower OBVIOUSLY the useful life will be drastically reduced. I have it on excellent authority (not UVL) that the Red Life/Sun (630) will provide ~95% of what the plant needs, SO, why waste money on 660s (until mid-flower). Follow this logic and you will double the useful life of UVL 660s

Any questions?
