Joe get a few easy grows under your belt before you spend too much money. There are several products and techniques out that will increase the yield and over all quality of the final product. I do prefer a commercial flusher it does work faster and does a better job. There is no taste left behind they do a great job cleaning out left over nutrients. You can grow easy or you can work for your bud. The difference is easy is a few ounces and if you work at it you can yield much more. It's all about the environment and the correct nutrient balance at the precise time of the cycle to yield the most. If you don't have one you should get a good book as a reference guide it will save you a lot of time and stress.
