Absolutely new to growing

[orion420]

I am curious what yields I can expect from a pre-assembled hydro grow box equipped with a 150w HID system with CO2 and proper nutrients. Per plant roughly. And what things should I do to ensure maximum yields?

Hey and welcome to the community!

There are MANY variables that will dictate your yield from the plants. If you add some more info there may be some one able to give you an answer but you'll need to list the space of the pre-assembled grow box, the type of HID light and their distance from the top of the plants and brand of nutrients, the method of Hydro and feeding schedules. On top of that any methods you may use to increase yield and the strain you're growing.

I guess what I'm trying to say is your yield will depend on how you optimise your grow, more reading, more knowledge, bigger yield.
