So im going to have customized t8 grow tubes made (im not pushing them on here yet so dont worry, lol)
The big brand led lights use a spectrum ratio of 3-1, 3500k:6000k, and they sprinkle in some 660nm red lights also.
I’m thinking of using this same spectrum, and adding a small amount of 365nm uv-a to the spectrum. The spectrum ratio would be 12:4:2:1, 3500k,6500k, 660nm, 365nm. It doesn’t cause any plant damage, but you will need to wear glass when you’re working with your plants, which we should all be doing anyways.
If you look it up, UVa will add to trichrome growth. I added a blacklight (also UVa, usually 385nm) tube to my other tubes and had solid results. I also used live soil for the first time, so its anyone’s guess.
The question is to UVa or to not UVa? The cost on the tubes is the same.
I just purchased and am running the HLG UVA30…just in the am to mimic the intensity of the sun. From what I’ve read and seen from @Hellraiser…we wont be sorry. Trics and a ton of them.
And hell, a built in tanning booth ain’t a bad gig either…just kidding.
vegetative period of your plant’s life cycle. It’s light is 80% 5500°K, 10% 460nm blue, and 10% 380 nm UV. Never did a t8. This is what i use i really like it.
So you like the UVa and you think I need to add some IR far red? noted!
On ebay this is close:
Prices are similar, but my lights will have UVa…also a realistic spectrum as well as better branding and marketing. The english on this ad is very sub-par.
