Use a green bulb, it won't affect the plants. Blacklights are NOT for growing.
there is a bit of controversy over using black lights, or rather any form of uv during growing.. but you'd definitely not want to use it, or any from or light during the lights off period as it would affect the flowering period for sure.. the only light that they say is safe to use during lights out is green, as its the spectrum that plants don't pick up the color.. but i wouldn't even leave a green bulb on for extended periods during lights out.
Just like to clarify for anyone else reading.
I may have to try that, the next couple months I am setting up everything and getting my ducks in a row, but one grow I may have to do that.
yah, like i've said, i don't know all that much about it, but i have done a lil reading on the topic.. i've yet to make up my mind really as to whether or not uv is indeed beneficial to growing or not.. but i would love to see some expirements done on it to either prove or disprove the theories.
i don't think you sound like a meany at all, lol.. i tend to agree with you.. i try to avoid interrupt the ladies when they are sleeping at all costs.. i know some people say that the green lights are fine at dark, but i don't think i would want to use one for any extended period of time during lights out..I know I'm going to sound like a big meanie, but there's no excuse for entering the grow space after lights-out
It's almost impossible to go about doing this regularly, without damaging the yield, or interrupting the bloom phase. It's hard to even gauge just how much damage you've done, unless you compare side-by-side what your specific environment can produce, without darkness interruption.
Do your work during the day. If you can't? Set the light schedule up so you can... if you're at work all day, let that be their night time, and have them go on when you get home. So long as their night time temps are still cooler than their day time temps, you're golden.
