Trinimom, please tell us what you are confused about? Perhaps we can help if we know the specific problem.
Please keep in mind that we can only talk about what our specific experiences are with OUR growing conditions. They are different for everyone and each of us has to find what works (or doesn't) for us. We might try something that is suggested here and it might work or it might not.
As far as Keiki-pro is concerned it is a product like any other product and has a specific purpose. Some might like to use it, others wouldn't touch it with a ten foot pole. I like to experiment and the loss of a plant along the way is my way of learning what works for me. Any, if something does work that's wonderful, and if it doesn't, at least we/you/us tried.
Please say around.
Al
