--Indoor Grow--

Ok i am going to try my first indoor grow, i have my lights and fans and all that under control, BUT i was wondering how i can grow
a plant that is really short and bushy out of
normal bagseed?

You can top it or 'FIM' it, which stands for "Fuck I Missed". Check out MBlaze for an amazing technique on 'FIM'ming.

Here's a link to it: https://www.rollitup.org/advanced-marijuana-cultivation/200413-fimming-m-blaze-complete-how.html

Look up low stress training LST. You get the plant to grow where you want it to.
