I actually went to the trouble to buy a Solarmeter 6.2 and measured the difference in a PURE UV 2' T5 and a lightly used Reptisun 10. The readings posted over at RIU months ago. Not that its science but its the closest thing I have seen linking actual measurement. Love to see some REAL testing instead of butt hurt posts by dudes who just say this or that UV light looks better to me or feels more like sun on my skin or some other BS. I cant say if it helped since I dont have room to run a side by side in different tents or such with and without UVB.
I keep asking the stoner science professors to show some info besides what they "hear" or what they think or what they "see" or "feel". I think some of them are sales hucksters most likely. I have spent real money out of my pocket to compare in a no way scientific manor and make no claims one way or another.
Cheers....So you went and bought almost the same meter I've had for years (6.5 is better for the task and certainly in units most understand easily); one that I recommended and have already posted in depth details on, sweet, what did you test lights wise, just a couple? I’ve tested over 30 sources. UVB has pros and cons, anyone using GH and outdoors to grow many plants can clearly express this. You ever see clumsy bugs/bees in a GH and wonder why, yup no UV, big part of the way they see.....
I have excellent UVB lights here (https://www.ushio.com/files/specific...blacklight.pdf
- the 306nm ones, you won't find anything close to this in output for wattage or costs), safe and easy for me to use inside but I don’t often anymore fwiw. I also know my basil in my GH looks much healthier but pales in comparison to my outside grow basil for terps and flavor. Take it as u will....
