Is it time to trim?

A question from a fellow grower:

Is it time to trim? It’s about to go into a cabinet with four sides of reflective material. Yes or no thank you.

That’s a matter of choice , but if you decide , don’t get snip happy , because the big fan leaves are the solar panels , lungs and heart of the plant , so trim only the very bottom if you decide to prune . Remember trimming can cause a plant to stall and stunt its growth , approach wisely . You can also download the grow bible here and do some research to get a better understanding .

Second question:

Is this a herm? If so should I waste any more time?
