Hey NCH, your plants look like they love you! Sweet looking young plants! Our methods differ greatly, but the end result is what counts.
I try to stress to new growers how different each method of growing can be. There is no "right" or "wrong" way. Only different ways. As long as whatever method used results in healthy, fast growing, maxed out buds, then it's one of the "right" methods.
Each type of hydroponic method can be hybrid into hundreds of different ways to accomplish the same end result.
I firmly believe that hydroponics will be the only method of mass producing plants and produce for the population of the world, eventually. People keep producing more people and the population of the world keeps increasing at a rate that will make soil growing obsolete eventually. Hydroponic food production is the future. Hydroponic Weed Production is the present......hahahahahaaha
If anyone reading this thread has NOT read Dr. Howard Resh's book "Hydroponic Food Production", you're missing out on a fantastic book full of ideas, methods and photos that will make your mind twirl with thousands of ideas and your imagination will run wild with projects you think of.
It is, without any doubt what-so-ever, the best book about growing plants that I have ever read in my life, and I've read many hundreds of that type of book.
It's expensive, but worth every penny. If you buy it, make sure you get the latest edition. He keeps the photos and methods updated in each edition.
