Use the nutrient solution given in the Nutrient Solutions section or a solution prepared from commercial premixed nutrients. Pour the solution into three containers. Adjust the pH of the solution in the first container to between 5.5 and 6.5. This solution is the “check” or “control” for the experiment. Lower the pH of the solution in the second container to less than 4.0 by adding small amounts of dilute sulfuric acid. Raise the pH of the solution in the third container to 8.0 or higher by adding a dilute sodium hydroxide (NaOH) solution. Test the pH of the solutions with an indicator.

Plants will usually display definite deficiencies if required nutrients are not present in adequate concentrations. The following symptoms may occur if the level of one mineral nutrient is not high enough to be within the range needed for best plant growth. A plant may exhibit a particular symptom for reasons other than a nutrient deficiency. However, if one of the deficiency symptoms occurs, a lack of the proper nutrient may be suspected, and the amount of that nutrient should be increased.

Let’s face it, you have probably heard that drinking tea made from the green tea plant is good for you. But did you know that it is being hailed as one of the most promising anti-cancer compounds ever found? Serious stuff!
So here is a little background on the green tea plant, or to give its proper name, camellia sinensis. Advanced Nutrients Hydroponics
Green tea comes from the same plant as our more familiar black tea does, but it’s the way it’s produced that makes all the difference.
The green tea plant is picked and the leaves are steamed, then rolled and dried. In doing so all the powerful antioxidants are left intact, for it is these which provide us with the amazing health benefits.
