topping vs not topping

ok if ur growing in a room 2m high (plenty of room imo) do u gain any advantages from topping? how does it effect yield? does it have varied results depending on set up and strain?
if so (hyperphectiaclly of cors) i got 10 euforia seeds in a nft setup under a 600w hps (also have a 400w available) room 1.2mx1.2mx2m

so to sum up, should i top? and shud i use the second light?
thanks adz

if you do top, plan on vegging for a few weeks after. don't do it close or into the flowering schedule. wait for about 5 -8 internodes and then top, wait a few weeks for the lower branches to start shooting for your light, then tie 'em down and spread them out evenly so they all get good light.... then start flowering. I usually do this to keep mine from getting taller and it usually helps the yield out alot, but some strains don't work very well with this method so do what makes sense as always..

agree with cjsesh00

ok thanks. wot about the 2nd light? is it neccicary?

that's not a good explanation of what happens when you top them, you're just showing off. with every right, though.

I believe it is northern lights. I can't take credit for those, a buddy of mine grow those ones. He is who is helping me with my first grow that im working on.

i believe you get more yield when you top a plant. under lights there will be more plant closer to the light when its topped.
instead of 1 top bud close to the light there will be 2-4 top buds close to the light
more light=more bud
