Black lights are good for your plants Controlled studies have shown a significant positive effect on a plants health + metabolism/growth - particularly in young plants - when common black lights have been used in conjunction with HID lighting. Most black lights have a wave length of 300 to to 450 nanometers which puts them in the far blue/violet spectrum with most fixing in about 400 nanometers. Far blue or UVA wavelengths - would be those produced by a rising sun. So if you so desire - I recommend placing your black light in your chamber and timing it to come on 30 minutes before your other lights and turn off 30 minutes into your regular light cycle
I'd be concerned having the cycle of the light turn on 30 minutes before lights on, I haven't had to deal with light leaks in ages I don't want another hermie showing up. Oh wait I just read about it being for more young plants, If I run 24/0 there's no way to take advantage of this correct?
30 minutes wont give you a hermi morange - IMO Its about maintaining a stable photoperiod - the duration is secondary. I've seen grow cfl's which turn down to 5% power at night - to replicate moonlight. I know this sounds like i'm bullshitting now but I will re find my references - they were obscure papers on brianmc.
Most black lights produce a lot of 400nm light. Google Image Result for https://growershouse.com/images/plant_chloraphyl_chart.jpg
The moon gives off such little light, like .25 or .30 foot candles, I don't know if that's even enough to register to the plant.
have you ever spent much time at high altitude? In mountainous regions - Moon and starlight is very bright indeed - this would imply that indica plants would be more likely to benefit.
no that is bullshit - black lights produce heat, light, sound/vibration and lots more. It just shows that Reputation means nothing in regards to credibility
In respect to a cannabis grow they only add heat. Course; Ed Rosenthall, Jorge Cervantes, Greg Green, R.C. Clarke, and ohh about 99.9999% of all growers could be wrong I suppose. Don't You think this has been discussed before? Even had head to head tests done? Maybe on this site even? You are very niave for a Pro-Grower IMO
who ever said i was a pro grower? I have quite clearly mentioned that i'm a novice - i just like to read a lot - i dont belive everything i read but 99.99% of info i have seen says plants enjoy 400nm light - - 50 years of reserch on photosynthesis - backs me up on this - the average black lights produces a lot of 400nm light With this in mind - can there be any debate as to there benefit as a supplemental light? If you'd like to see my grow setup then keep following this thread and i'l show you the techniques i use - with a video post.
