Cutting roots in older healthy plants

Hello my fellow cannabis growers.. I have some plants in veg that have been sitting in 2 gallon pots for awhile. I waiting for my other guys to catch up before i put them into flower. Should I prune the roots when I transplant into bigger pots, never done it before but I'm thinking due to the elongated grow this may help them take off...

You will probably have to if they are curled around the inside of the container.

??? WHA ??? Cut roots,,,what ever for ??? Up potting? They'll still spread out! Why would you risk infection? Stress? Long recovery period?
Nah,,,not the best idea. To many chances for a major problem to arise.

And on a humorous note:
Damn, and Jorge says don't trim ANY leaves....This idea would KILL the guy.....lol

when i x-plant, i always run a blade 3-4 times up the side vertically (not too deep.) cutting the roots like this, promotes root-growth. if you keep mothers, this also comes in handy, to keep them the size you want. you can really saw off a big hunk of roots, and the plants do fine...

Thanks, I did cut some root threw some great white into the mass and then planted. The girls are looking good.

^^^^^^^^^^^^^^^ Yep yep yep, just like any other plant, but I would recommend clean cutting tools.
