Your Grandpa's Weed or is UV supplementation really needed?

I was lead to believe that the best light to grow anything under is SUNLIGHT does that mean to get the best results under lights a True full spectrum of all the colours of a rainbow would be the ultimate indoor grow light or is that just a pipe dream?:peace:???????:leaf:

Tis pretty much true IMO but there are things we can do indoors to enhance things a bit and the sunshine is not the same everywhere

Sunlight can burn plants, it can be too intense, it can be obscured, you can't control the cycle timing, and the HVAC cost to climate control greenhouses can get straight out of control.

In my humble opinion, sunlight sucks next to modern LED.

Thanks for the clarification I am running a LED 300 w cheapo it has uv an ir included
I think it is only about 220 w really also 3 panels there only 45 w each.:leaf: :peace::leaf:

Full spectrum LED sources such as the CXB3590 COB LED I'm using right now are unequivocally the finest lights I've ever grown under. I'd suggest 3000K for best blooming performance.

If sunlight sucked you wouldnt be adding UVB in your grow rooms to try and mimic it ttystikk come on. Sunlight is number 1 buddy unless you live in a fucking cave

I didn't say the spectrum of sunlight was poor, but I stand by my list of reasons why I like indoor lighting better.

And I've yet to add UV to my growroom lighting. No one has complained.

Speak for yourself. All of my friends and I certainly do.

I love cxb"s and v29s but i agree w dude. I'm not into spending time under them. Ive got an agro max as well, reminds me of radiation therapy, sickening.

I wouldn't suggest spending any time under strong UV sources at all, with one exception; if you have psoriasis, UVB is a very effective treatment.

I agree with leprechaun that agromax is a potent fucking bulb. I wonder if it's so synergistic for him because of the t5's he uses??? In my flower room the plants respond with far more love to the hortilux pure uv jawn.

Spectrum tells you everything less is not more overall take away spectrum you take away a quality
I am happy you are happy with leds but less is not more

COB LED is a broad spectrum light source.

While they do not emit any UV, I see this as an advantage because people will work under these lights and they don't need the exposure.

You see, now you can create a dedicated circuit with UV specific lighting that might even be a lot stronger than naturally occurring conditions and run it when it's most advantageous- and not at all when people are around.

Note that never once did I say that COB LED spectrum was superior; I listed my reasons and I stand by them. That said, the safety and performance potential of a separate circuit cannot be overlooked.

My grandmother got macular degeneration just from a lifetime at high altitude living in Colorado, which is tiny compared to the UV output of most horticultural lighting. I just don't think growing frosty nugs is a cause worth going blind for, especially if the fix is this simple.

Yup of course it's not worth it ya need to be careful with uv as well as any focused high intensity light both will mess you up. Uv is just sneaker in that even dim it can damage

Very true, if speaking in general, and referring to "The Allegory of".


Regarding "Sunlight" VS "Artificial", it's sunlight all the way. However, the environment associated with "Artificial" lends it the nod for our purposes. The controlled environment makes all the difference. That, and although "Sunlight" is superior, it's varied intensity throughout the day (low intensity is the issue morning and evening, high intensity wouldn't be an issue with indoor supplementation/control), it's "inconsistency" through the seasons, and limited ability to manipulate long/short days (relative to the level of control indoors) throughout the year hinders the suns use (6 to 1x (e+c).

Were we able to utilize the full intensity of Summer Solstice sunlight in a complimentary indoor environment, "Magic" would happen.

It actually does, but most of us can't afford it 8)
