To Arrion: Thanks. Is that 1 cup of citric acid solid crystals? Is the role of citric acid for adjusting pH or some other reason? I looked up the formula of Citric acid and it just has C, H & O, so does it enhance oxygenation? I don't know Borateem, i looked it up, it is bleach for colors. What is the role of Borateem? It is good to hear from a professional grower. Thanks.
To GPS: What source do you get your ready made
nutrients from? The on line as well as physical stores I looked at have the small bottle set selling for no less than 30-40 and it does not make a whole lot of solution.
My interest in hydroponics is not commercial, folks. I am just a hobby gardener. Thanks.
