Top when lights are on or off?

Hey guys, I know that the auxins move around in a plant according to its light cycle so is it best to top when lights are on or off? Thanks

I always top when lights are on, I really don't think it matters....

agreed....

It's a weed...top it whenever you want and as often as you like (in veg).

well i top when the lights are on, and I think it actually does matter.

Here is why (taken from my GF's little sister's "Biggest Ever Book of Questions & Answers, awesome toilet read)

tips of plants such as leaves can detect the direction of light, and chemicals are released to make them grow more on the lower or darker side, thus turning the branch/ leaf upward.

So I can see that if you did this at night, it would just lay there limp and maybe rot off.

It doesn't make a bit of difference. That being said, you should only top when your plant is vegging and since the veg cycle is 20/4, how often are you really working in your room when the lights are off?
