Newbie needs help learning about nodes & topping

Newbie needs help learning about nodes & topping, what are nodes can somebody post a pic explaining and please tell me how and when to top my plants and take clones. Thank you all

go to general mj growing theres a couple threads explaining how i myself
take bottom branches two weeks in flowering so i know there girls
making a 45 degree angled cut (a must ) make a clean 45 degree cut if the first cut isn't clean
place directly into wet soil in seperate small pots some people use the red party cups
place directly into a veg room under a 20 on 4 off cycle
they will root it takes time just keep the soil moist and youll seen them grow eventually 2 weeks or so
some people use clonex and go directly into soil sum root in water i find the easiest way is directly into soil and on a cycle

Thanks alot

A node is the area where the branch grows off the stem. Any place on a branch or the main stem that has a branch growing out of it, is a node.

Topping is usually done when the plant has it's first 5-6 nodes, not including the node from the original round leafs or the set right after that. You can take the very top new set of leafs that are growing in and cut them off down to the stem (or you can FIMM which just means you cut 60%-70% of those tiny leafs off). Or you can cut the top 3 nodes off if you are going for an even canopy.

I don't know much about cloning myself, I just grow from my own personal supply of seeds.
