Go to youtube and in the search engine enter 'I grow chronic.'Also I have this book called How to Hydroponics fourth edition by Keith Roberto its a complete guide on how to build and operate hydroponic garden.Its well worth the 25 bucks shows how to build all types of hydroponic systems.The easiest system to build and have great results is Flood and Drain(ebb and flow).All you need for the system is a grow tray ,reservoir ,pump ,and preferred medium.
