I currently have a drip irrigation system set up. I recently watched the Video by Mr Green "I grow chronic". In the video, he used the drip system for the vegetative state and an ebb and flow system for the flowering stage. I was wondering if it is absolutely necessary to use an Ebb and Flow system for the Flowering stage, or will I get good results just by using my Drip system with an HPS light? Any feedback would be greatly appreciated.
