am vs pm best time to top?

as the title says is there a better/ preferred time when this should be done?

it really doesn’t matter .. if you’re topping maybe when you’re not super stoned so you don’t FIM it lol. I’ve read that some do it before lights out to give it some down time to rest up from the stress but I’ve always done it during lights on, I run 24/0 during veg

Agree with Lowkey, it does not matter, the most important thing is to do it when you have enough time. It is no fun playing beat the clock. Good growing...
