Scrog net will be necessary down the road but I'd recommend to only install the net after week 1 of flower to allow the initial stretch then spread her out and let her grow up and over the net. Without a net your branches will be so heavy of amazing buds they will either snap or be leaning against the side walls of the tent or floor. You created a beast she'll need support lol. You can see in my strawberry lemonade what I'm referring to.
