question about trimming please help. simple question

hey guys i have a pretty tall plant already and the bottom is growing a lot of newer growth. i wanted to trim a lot of the bottom because its not getting any light down there so i have a few questions.

1. can i trim the new growth straight to the main stem? or do i have to leave a little and then wait for it to dry up and then cut the rest off?

2. how much can i cut at one time without hurting the plant?

all the lower growth im talking about is pretty weak and probably using up a lot of resources trying to keep it alive. so please help me out guys...1st grow

Trimming is wack but if you must do it I would use something sterile to cut with and do not cut it close to the main stem I would leave 3/4-1" left. I would cut it all at once either you dont want to shock it too much. Do a little and water the plant and wait a few days to see how the plant reacts. You cant add more lights to the side of your space?

yeh its fine to do,cut as close to the stem as possible,and make sure the scissors are clean..peace

I always trim the bottom third, with a sterile scalple. I do it A few days befor flower period. I trim the lot in one go, probably 6/7 branches. I then make clones with them.

I always do a little at a time to reduce the stress to the plant. Second I like to do little to give the plant time to benefit from the big fan leaves as long as possible.Sucks when they start covering great bud sites.
