Go with General hydroponics for a start on nutes. You will need cal-mag plus for sure.

Stay away from rubbermaid , it degrades in the light.

DWC, 5 gallon bucket. You can get 8 to 10 inch net pot lids that fit the buckets. Plenty of hydrotron rock. A big air pump and lots of air stones.

pretty much all you asked has been answered a 100 times but keep asking.

Say, how many 100 are we going for. LOL
