Some advice for a starting grower

Some questions from a fellow grower:

I am planning on starting my first grow and will be doing so
indoors via hydroponics and have a few questions I hope you and assist

Net Pot Size

I will be starting
with an indica dominant strain and when I get the process down I will
shift to a saliva dominant strain. Is there a difference between using
6", 8", or 10" net pots for growing cannabis?

LED Lights

Is it better to use an LED that’s equivalent to a 1000W HID or two 500W LED lights?My concern is getting the proper amount of light to the entire plant.
Any comments you have would be greatly appreciated.
