I got sunglasses. But I'll check out the UV goggles. thankyou very much.
Trichomes, THC and UVB light.....
- Thread starter tahoe58
- Start date
I did not read the entire thread but skimmed most of it, and it brings up a question I have asked before. If I take the research as it says, then what would be wrong with Actinic lights generally used for corals on fishtanks. Here is a link that gives a little overview of them: Aquarium Lighting information
Well thanks for the advice YG. I'll keep you brothers updated as to what I learn. I am worried however that the bulbs I find that are lizard lights seem to be rated at 25watts.... and the T5 system I was referring to is 24 watt bulbs. I'll do more research. Thanks again.

the general sense at the moment (to be confirmed) is that these lights may not provide adequate intensity of UV to gain the benefit that we seek. but like I said, that is yet to be tested and confirmed. Within the thread there is a chart of the various light outputs and the lihhts you reference I believe are on the lower end of the output....but the reality is we are still not certain about whether or not that is an issue to improving the potency and growth of our favored weed! 
Ok, I understand that, its just unknown at the moment. However, considering what the spectrum of those lights are and what was implied in your original post, do you feel that they would offer some benefit, even if they were just secondary lights backing up the primary? You know, just a supplemental type of light or maybe even a nightlight? I am just really interested in this, because I honestly see the effects with and without those lights in another application. No pun intended, but there is a night and day difference when used on aquariums, in all aspects of life.the general sense at the moment (to be confirmed) is that these lights may not provide adequate intensity of UV to gain the benefit that we seek. but like I said, that is yet to be tested and confirmed.

MY UV light is 300w, and has been running constantly, and as the seedlings only light source for 45 hours.
They are vibrant, and growing just as well, if not better than under a 400w MH.

that is so cool.....and thats a 300W bulb....very interesting....

They say a picture is worth a thousand words...
The light is now a mere 17" away from the tops of the plants... and i fear i shall have to move it in to 12" maybe before the day is out.

Thelight is now 11.5" away, and the plants seem to be ok. Aside from the stretch, which I believe should now be halted by the closeness of the light.

How much water are you giving them? Same as normal, less than normal, more than normal.

I pre-soaked the medium... left it to drain for 24 hours. Then placed in the seedlings. The feed I put in came to 0.4ec.
They've only been in for 48 hours. I'm not expecting to have to feed them again for another couple of days. If it is that quick where they need feeding before the 1st week of veg' is up, they will recieve the same 0.4ec feed. I have 3litres made up ready. If they last the week I will throw that feed away, into my garden... and make a feed up of 0.6ec
Very well. Now, I have been running fishtanks far longer than I have been growing. I have actinics out the yinyang that I can use. I am about to harvest, and then make a few mods to my box. My question is this, in your opinion how should I experiment with this with actinic lights? Should I run them on a separate timer to come on at different intervals of the day(loosly speaking of course), should I run them at the same time as the other lights full time or should I make them a nightlight, the "white lights" go off and the actinics come on during its night cycle, or even leave them on all the time and never shut them off? I dont know, I think there is really something to this, and this is an experiment that really cant go wrong. As long as I have what is considered adequet light as it is, then adding another light certainly cant cause any ill affects, if its the wrong spectrum then the plant will not respond to it at all is the way I see it. Any advice??simple answer yes, extent of benefit unknown....but I do believe that the value of these light spectrums are what is missing from indoor pot...as explained else where in the thread.

what skunk said...got me outta making an ass outta myself with some highly (un)intelligent answer....hahahaha! My idea is to integrate the UVB at a level that allows it to be on with the other lights....though there is also that "moonlight" option to bring into the equation - there are really only 12 "daqrk" days in every moon cycle. I am still working on what my first experiment is going to look like.

Hey Tahoe58. I live down in the valley (off 50E near Dayton) from you so we are kinda close. I used UVB light and just harvested some fairly good stuff. I haven't smoked any of my tops yet but the lower buds were pretty "dreamy" as MM man stated. It stands to reason that we need that spectrum of light. I used a 24" UVB bulb plus a compact flou. that rated it as 10.0" lizard light. During the first part of flowering I had them on 2.5 hours a day then slowly worked up to 4 hours a day, this during the mid day of lighting. I always turned them daily so they would get UVB evenly. Now my clones are flowering so I'm doing the same routine. I haven't done any control studies but I think it may have boosted the level of THC production. Some of the powder on my rolling tray looks like coke all ready to toot but a little yellowish. The verdict isn't in but I'm really happy with the initial results. I'm a bit new to growing so keep that in mind.

hey Skunk...spending a little time on my ideas regarding a multi-setup. and came across this regarding UV LEDs....
Ultraviolet LEDs
Ultraviolet light is divided into three bands: UV-A, which is fairly innocuous; UV-B, which causes sunburns; and UV-C, which kills things. Most UV-B and all UV-C from the sun is filtered out by the ozone layer, so we get very little of it naturally. LEDs emit UV-A. 400 nm is a pretty common wavelength for UV LEDs. This is right on the border between the violet and ultraviolet, so a significant portion of the light emitted is visible. For this reason 400 nm UV LEDs are sometimes rated in millicandela, even though as much as half of their energy is invisible. LEDs with lower wavelengths, such as 380nm, are usually not rated in millicandela, but in milliwatts.
just thought I would add this into the mix of knowledge....

cool....thanks for the excellent info...and direct experience.
PS - not sure where you get where I'm at but I don't think Dayton is anywhere near me? cheers!
