UVB BULBS

[oldmac]

Red 660nm will produce more trich's the one can shake a stick at and know harm to you or your plants. Leave the UVa,b,c to reptiles.

Dogznova;

There are some subjects that I try to avoid on these boards....one of them is the use of UVB supplemental lighting. But you've pushed my LED button so I guess it's time for me to address it.

First, I have noticed a slight increase in trichome production using LED lighting. The two Procyon's I used for awhile showed this effect, but they use red Cree LED's at 635nm.....not 660nm. While the full bandwith probably includes some 660, it could not be enough to explain the effect. Just possible the effect comes from the blues, Cree's peak at 450nm, and thier bandwith may include some UV or near UV. Hmmmmmmm interesting.

I currently have 2 Ti Pro-Blooms and they show even more trichome production then the Procyon's did and you know what, they have 660nm! But wait, they also have (drum roll please) UVB (ta da). It's one of the reasons I bought them, they where smart enough to use an enhanced light band that included UVB.

Main reason I avoided talking about UVB, I know it works and I can't see why there is even a discussion about it. It is so easy to demonstrate. I've tried back to back grows with and without, and there is no doubt in my mind it makes a big difference, not just trichome production but THC production.

Maybe you should have tried a little experiment with UVB before moving on to Martian Night lighting.....

Rusty If you can get a hold of some red 660 give it a try. Soon there will lots of proof. Your right, it would be foolish of me to tell you I can 100% proof this fact. I can't nor will I try.. But this proof you want does exist. It's just not public at this point.

Rusty here is something I always like to say.

Laugh at me, Laugh with me, as long as your Laughing. :S2:

Also Rusty I enjoy reading all your post. You've got a great way of making your points. Keep those fingers typing. :thumbsup:


Old mac you are right. But I personally don't think your plants need that uvb like you think they do. What if you could get the same effect with just 660. Would you drop that harmful uvb. I think most would. Sure a small amount of uvb is just fine, don't get me wrong. I think the future will show that your particular purpose for uvb (trichome production) is not needed and is harmful to you and your favorite girls. :smokin:

Sorry.... I just seen this.

I have done experiments with UVB before I moved on to Martian Night lighting... Someday you will come over to the dark side. :jointsmile:

Yo' Dog,

Sorry.....I couldn't help taking a cheap shot at ya.

You also touch the other reason why I don't discuss UVB, there is a safety issue. It's also why I never talk about certian methods for CO2, I really don't want to be responsible for hurting someone.

While the science is sketchy about trichome production, it is pretty clear about about the production of THC. UVB is necessary for that.

I'm still waiting for the Martian Nights to produce an "ah ha" moment, then I'll look into it. So far tho I've been a little put off by you or your uncle's various poor takes on fundemental horticulture, but I am still interested.

Looks like that's two holes in my head now. Sorry my uncle and I offended ya somewhere down the line..

Hey Dog,

You and your uncle did not offend me at all, it's just that a few of the things I've read where not based on sound science. That then makes me leary to imbrace other things that are said. I have said to you and others on the martian thread, I appreciate the expriments and efforts you're making and I really am looking forward to a break thru using the method.

Plus you can't be all bad, you see the wonders of LEDs just like I do.
Here's a LED only trichome covered (young) bud.

[Dogznova]

Nice flower oldmac. I'm glad I didn't offend you. :thumbsup:

[oldmac]

Thought I might post a pic of a small finished bud, that's manicured.

This was grown under T5 vho and UVB. No LED, No HPS.

[Dogznova]

Nice. Is that dirt or hydro?

[oldmac]

Hi Dogz,

That's both. It's hydro drip to waste grown in Pro-Mix Bx. I consider pro-mix dirt, I would prefer growing in aero/fog, and that's comming very soon.
