Plus there are also so many people here to help you. Anyways, here's the link: The 30 minute 6 plant aero build

You could also go with hempy buckets (super easy passive hydroponic system)

Or bubble buckets. A bubble bucket/DWC (Deep Water Culture) can be made into a setup like that link I posted where you have 6 (the amount is totally up to you) net pots cut into the top of a plastic container and just fill it with a good nutrient solution, and throw in a couple air stones attached to a pump and voila! Nice little hydro system.
