I was just going by that arcadia website that says 12% uvb and the one you posted says 10% uvb, thats a 20% increase. Also I'm not seeing the arcadia ones in that chart. As for which one to chose, I couldn't help you there as I don't use and most likely will never use UV in my tent. I'm sure they all will give similar results.

Are you against using UV because you don't believe in the theory behind using them or do you not like the idea of UV rays floating around your tent? Have you ever tried using them before?

I read up on it before but I just didn't find the evidence to be that conclusive, also I don't want to add CFL/T5's to my space.

That is an HPS spectrum from solistek, as you can see there is UV in it. @Greengenes707 did a side by side grow with the ApacheTech AT600 R2 spectrum which has no UV in it and a 1000w HPS. He sent a sample of both for testing, though the HPS has more UV it produced less terpenes and cannabinoids then the LED sample. Im not saying its definitive proof but its enough to show me that added UV is not needed.

"LIMONENE!"

Haha - a great video.

GG made it sound like the heat from the HPS possibly cooked some of the THC and produced additional Delta-9, resulting in the 2% difference in THC between the two.

I guess I'll have to do a side by side comparison of two exact strains under similar lighting conditions, where one room has supplemental UV bulbs/stars in it and the other doesn't.

Thank you for sharing that video EF; I had no idea that they have public testing of marijuana! How cool!

@epicfail @AquariusPanta
In the hps's defense I had the glass on, so super limited UV if any at all...more like none.
But the same can be said about the lens on the apache I guess. So it was a fair trial.

From my experience, a good blue(450nm or lower...also available from a white led) will have an equal effect on trichome production without any negatives like uv can sometime cause. I have only added UVB once...I didn't notice anything and it was to an hps grow. I have not added it to led to see if it would increase the increase.
Then factor in the lack of efficiency when trying to add uv and I just don't see the reason.

One last little note...Apache's spectrum really doesn't have that much blue in it(about8%)...so I can only imagine that ~15% would make it snow on every leaf.

I have said it before but have been side tracked with other projects...a blue led saddle that universally fit every hps hood...gold mine!!!...just remember who's idea it was...I have proof going way back to my conception of it. ™™™™™™™™®®®®®®®®®

No that is not the reason...
The 25% total for the hps included delta9 and thcA... Delta9=2% and thcA=22%...totaling 25%(with all the other cannabinoids too)
As where the led had thcA=25% and Delta9=1.7... totaling 27%(with all other cannabinoids too)

I said the heat could have done that to it...who really knows what actually happened to get the numbers to where they were. All we know for sure is the final results.

Pardon me, I should have been more specific. I meant to say thcA when comparing the levels between the two specimens. I thought maybe that the difference in thcA may have been a result of the extra heat given off from the 1K HPS, therefore justifying your spoken logic and my reasoning (thcA converted to Delta-9).

Haha your idea of an blue LED incorporated saddle could be done. Where do you live (Guessing Cali)? I could become your pupil, your trusty sidekick ... :wink:.

Solid video GG. I've said this before and I'll say it again, I learn more through you guys than I do from my instructors at school!

:peace:

If the led had no ∆9 then I would say for sure that would have been it. But only a .3% difference isn't enough to say anything.
I will get around to the saddles soon.

I just realized a bunch of my issues with temperatures in my tent are stemming from the fact that most times I close the closest doors and this in return blocks off any fresh, cool air exchange that comes from the rest of the bedroom and furthermore prevents most of the heat within the closet from escaping, thus resulting in undesirable temperatures within the tent (86 degrees celsius).

I'm currently in an ongoing observation/study for when different elements are altered, such as the closest doors being open or closed. I'll throw up some numbers for different scenarios afterwards, just for the hell of it.

I spent a good part of my day off calculating and observing the different temperature ranges that took place when I augmented different factors, like the closet doors being open or closed.
The tent is 1.7' x 3' x 5' and the closet is around 2' x 6' x 8'. The room it encompasses is around 110 sq. ft.

What I found with the first test was that with the doors wide open, the 6" Air King fan constantly blowing in on low, and the 4" inline fan exhaust running on medium and turned on every other 30 minutes, that temperatures would raise to a high of 81.2 and low of 78. 8 degrees fahrenheit. A decent range within a given hour segment.

Another test showed that with everything staying the same as the previously mentioned test, but without the 6" Air King fan being powered on, that the range widened, showing a high of 86.4 and low of 79.4 degrees fahrenheit. Again, this was recorded over a given hour.

The third test sort of surprised me but eventually made clear sense. Everything was the same as it was in test two, except I allowed the 4" inline fan, running on medium, to be kept powered on for an entire hour rather than 30min on/off/repeat. The range was most preferable, despite undesirable power consumption, among the tests with a high of 80.4 and a low of 79.4 degrees fahrenheit.

The only issue I have with these scenarios is that the closet doors are wide open, exposing my entire setup and allowing the noise to affect the nearby surrounding (70 degree fahrenheit on the average). My solution is to crack the doors a little, in order for hot/cold air exchange to take place and to eliminate some of the DBs.

When considering power consumption, the first test proved most effective. The 6" fan, on low, operates at ~10W, while the inline fluctuates around 35W, on medium.

Anyhow, it was fun to do while watching my lady dance for me! She be getting her 'V' on for me if you what I be saying ;-)

PetMountain really packed these bulbs well; thick bubble wrap! The shipping/handling was sort of high but they did give me a 10% discount for becoming a member, which helped offset the total price a bit.

Hooked em' into their sockets earlier and they power on. I'm going to be running them for a few hours every morning before class, while turning them back on for another few when I return. The plan was to give my sour lady around 5 hours of direct UVA/B each day with these 2x 13W CFLs but if anyone objects to this, I will reconsider as I am new to using UV CFLs.

Just realized you haven't updated in a bit....still running the Vero's?
O yeah - I sort of let the thread die down a little recently as I've been occupied with other pressing matters.

The Vero's are still running, no problems thus far. I've noticed that bud production seems to literally stand out in the areas under the V18's, rather than the BlackStar. This could be due to the distance of V18's being closer but it's evident that the Vero 18's are holding up their weight quite well. I've already got my next DIY drawn up and planned out. I'm just now waiting on a few things to pan out before making any serious moves.

Hey AP, sometimes there are a few sneaky bananas hiding here and there. Although it usually takes 2-3 weeks of flowering for them to start dropping pollen and that bean seems too mature to have been pollinated by that same batch?
