harvest after dark period or not?

Iodine starch testing tell us starches stored in the leafs is used up through the dark period, who knows there could be something to it?

If you soak a leaf in solvent then put Iodine on it, it'll turn black if you do it before lights off, if you try it at lights on the leafs stays white/cream because there's no starch for the Iodine to bond to its been used.

That's an interesting science lesson.

I've always cut it at my convenience when it's lit up but I wouldn't write off some minor differences, I suppose the question would be is how quickly does starch break down?

Or, maybe it's advantageous to have it present?

Read years ago that it was best to chop them in the dark for this very reason, when the light comes on the starches go shooting into the plant.
That's interesting, it's logical, starch being present after the light comes on is science based its a fact, it's literally a test to check if photosynthetic has occurred.

Would you say it made a difference to the smoke?
