there both long but i want at least 1 short and bushy so should i top it
and whats the difrence of topping it now and again later on then just topping it later on
and whats going to be the diffrence between the plants if i top 1
should i top 1 please help?
and there indoors

please help fast

top it if u want to
are you wanting to due to height restrictions?
why help fast?
if u top it now and later on you will have 4 main colas
go and read sum stickies and do abit of reaserch on topping to obtain a basic understanding before asking these questions

I always top. Usually more than once

i would top if I was you. it will keep your plants uniformed

now that i didnt top mine I will always top all my plants, I learned my leasson, I only topped a few under a different light height and they turned out even and beautiful, the untopped are stretched and uneven. Live and learn.
