LED Without LEDs -My First T5 Grow

Just finished putting the Hobbit into mason jars after drying... 1.3oz total, light and airy but sticky as a mutherfucker, holy hell its like touching flypaper!

I love going through my flowering box and doing a little scratch and sniff, lightly drag a clean finger over a sugarleaf towards a top cola and sniff it...
My week3 BlueBerryGum is way more sugary and frosty than the others, and smells very clean, kinda spicy and piney
My week6 BlewCheez (unk. Sativa) isnt that frosty, but is developing these little fist like colas that are getting rounder by the day, and is now developing a nice purple color in the center of all the new calyxes, like a vibrant bright purple!
My week4 FruityChronicJuice got fimmed at about 3ft and is leveled out now, but is developing several colas that will fill in to be about forearm size! plus several clusters that are already getting bulky, sniff test... sweet lemons! love it.

Pics soon, Im getting about 12 2ft bulbs delivered tomorrow to complete my current setup, then pics :)

Just looked at the SPD for the Gro-lux. Thats actually a REALLY good full spectrum lamp. strong spikes just after 400, again ~430, quick strong spike at 550, and really strong output from 600-670. Wow.
Yes there are really nice bulbs out there with a strong red, BUT, as I understand it from Jeff @ UVL the 660 is a monochrome. That can be very useful to those of us who want to mix/match to achieve best blend for our plants

IMG457 - Copy.jpgWW 2 more weeks hoping to pull 2oz with this guy!

IMG462 - Copy.jpgthe fastest growing plant! doubled its size since the last pics! one week under t5 and co2! growth is amazing canatwait for the plant growth bulbs from wave point!

IMG464 - Copy.jpgIMG463 - Copy.jpgmy blue cheese yeild from 2 plants in a gal pots around 2oz dry harvested 2 days ago,this remind me i got to show pics of my purple b4 it gets harvested!

indeed, that is why I went after them. Having seen the chart, (shhh, I'm not supposed to share it either) I can say that it is still based on a tri-band base and that while it does appear to be very red in the pictures provided above, it definitely has larger spikes in blue and green than the red sun. Jeff@UVL said this was a necessity to achieve the strong output on the 660 range. I don't know the details on that. Also, the 660 spike is pretty big, basically has a "half strength" mini spike at 630, then dips a tiny bit, then comes back up to about double that height for 660... tapers back down around 670.

So the 660s spd looks kinda like a florasun's then, maybe a bit more intense (more phosphors) in the 660 zone, but otherwise same wavelengths covered? R/G/B wise that is?

It seems similar, but definitely more red judging by the picture. It's hard to compare accurately. Baically, while the flora sun has that wide low "swath" of blue that starts around 350 and settles around 570 in addition to the sharp peaks, the 660 has only the sharp peaks (extremely narrow) and no "swath" (I can't figure out a better way to describe that, sorry) so I figure that is where the extra red energy is offset. I think that it is pretty obvious the 660 has a good bit more red end just from the pics with that magenta hue.

Give me a minute, I am going to do some super imposing to see if evrything else lines up

Edit, okay: Yeah, the peaks line up as expected... however, here are a few differences:
(all observations are relative to their own charts only, as I can't be sure these are measured on similar scales)

-while the 440ish spike and the 550 spike on the Flora Sun are very uneven, with a lot more 440, they are almost exactly the same height in the 660.
-The Flora Sun's UV spikes do not exist in the 660.
-If you look at the Flora's chart, you will see a small spike at about 580nm. While that spike stays in the 660, the series of small spikes after that are completely gone, as well as the medium spike at 610.
-While the Flora has a small bump at 700, the 660 bulb does not but has a series of small bumps ranging from 740 to 800. They are very small, though.

Observations through scaling, which are estimations of relative distributions due to the scales applied being only relative to themselves:

Through vertical scaling, if I match the heights on the 550 spike and the 580 spike, it would seem that both the 410 and 440 spikes are significantly shorter in the 660 bulb... and that the 630 is a bump higher, and the 660 significantly higher. The valleys between are higher as well. I believe this would correlate with the idea of the bulb appearing so red.

In a similar move, I can scale the whole thing vertically to match on the 660 spike, but that wouldn't seem to make any sense because all the other spikes end up significantly shorter than the Flora's and there would be no logical explanation as to where the extra wattage is going from the missing spikes mentioned above, nor the extra wattage from the relatively shorter tri band spikes.

You cant really compare by looking. Have to do math. Where the flora sun 660 peaks just over 40 % . The uvl 660 peaks over......... I could be wrong. by my math that its just over 20%. More equivelant to the roseates. The flora suns do have higher peak in blue,green and red.. Basically the flora sun irradiance is measured in % where the uvl 660 irradiance is measure in w/cm2 . Similar to wave points which are measured in w/m2

Oh, well, I don't know how to do the math. I realize you can't compare the peaks directly, which is why I didn't, I was just using the super-imposing to make sure the peaks were all in the same position along the nm scale. I speculated towards the end of my post about the intensity differences, but I was clear to state that it was speculation.

But if what you say is accurate, I don't get why the UVL 660 looks so red dominant then...

Do you mean appears in the spd or the bulb itself? From what jeff said its supposed to appear as a white bulb like the guisseman midday.

Excuse me, I really do understand all the excitement here, but I have yet to see a compelling reason to spend $200 on 8 bulbs or more to produce 1-2 ounces per plant. Does anyone have a comparison of all this exotic stuff to regular T5's or the cursed HPS/HID?
Just curious, I want a compelling reason before I spend the $$$$$$$$$$$$

Read the whole thread. I.did comparsons with a 1000 w. 2 other people did comparisons to a 600 watt. Alot of people did comparisons to basic stock t5 bulbs.

um dude i harvest 3+ oz every week under 800w HID not T5 read the thread thats a monster for what im doing im getting closee 1.5 gram per watt. i now veg under par T5
