How long to harvest?? (Male edition)

I’m reversing this clone with CS, it took much better than I expected, plant looks totally normal none of the dying or curling leaves.

the pods are growing quick but I have no idea when they’ll be ready to use.

When they open

They grow at different times so they will open at different times...for as long as the plant lives/grows.
I've found it has been about 3 to 5 days and I start to see pollen dust on a few leaves.
I LST mine and let the pollen fall on to a piece of parchment paper then I scrape it up and put it in a storage container.

Holy shit that’s some serious training lol.

that’s a good idea, mine are clones in solos so maybe I’ll just lay some paper down and tilt the cups over them.

Are there any signs that a pod is about to open?

If you have other plants in there, finish them somewhere else.
I did mine in a coffee cup.
