for your first time i wouldn't go with aeroponics. They can be finicky systems that can hurt you harvest. A hydroponic dripper system or table system is easy enough to run.

And there are factors involved when figuring out how much and how often to water. I did a flood and drain table and what worked for me was flooding for 5 minutes every two hours. And as far as nutrients, i found House and Garden nutrients to be the most simple line out there. The prices seem high but the samll bottles seem to outlast the bigger competitors bottles.
