black light

[Mr 816]

FjCan I use a black light when my lights r off in the 12/12 stage.

No you can use a GREEN light. And when I say green light I mean actual green light not a light thats been painted green.

$12 and even thats probably a rip off.

Sunblaster brand clf and high output t5's make a green spectrum that you can use the your lights are off

no you cant. on top of that before you ask "can I use it in flower?", you could but it would be a waste of time also since it only emits a specific band of UVa.

Any long exposure to black light will harm plants of any kind.

Just do your shit that you need to do to your plants when the lights are on.
Need to spray, do it when they are about to go off, or leave them on for an extra 15 mins... then don't open the door anymore.
Problem solved

I agree.
even if you do go into the flower room when the lights are off, the little bit of exposure they get won't hurt them.
your usually not in there for hours.
