    The Difference Between Rainwater and Tap Water

    Not all water is created equal especially when we're talking about the health and development of plants and people.

    Why Rain is Important

    Rain or the lack of an adequate supply can have profound effects on farming and the communities that rely on the harvest.

    Anatomy of a Seed

    It all begins with a seed and this article dives deep into the 5 primary parts of the seed that make it all possible.

Lesson Overview

Perfect water contains micronutrients and carries a perfectly balanced pH. This lesson tasks students with creating perfect water for use in the Lab, something that closely mimics the value of rain water.

Goals

  • Students will be able to describe the formula for producing perfect water.

Outcomes

Students will experiment with various additives in order to create a recipe for perfect water to be used in the Lab.

Teach the Teacher

  • Testing Hydroponic Nutrients

Tools & Materials

  • 5 gallon bucket
  • Ascorbic acid
  • pH UP
  • Liquid nutrients

Activity

When is the last time you really thought about the water you drink?

The notion that water is water couldn’t be any further from the truth.

Water has a specific pH which ranges from acidic to alkaline based on the source. Water also has micro-nutrients if it is sourced in nature from streams or rainfall. And if the water you have access to is coming from the tap then it likely has chlorine or sodium hypochlorite in it.

The water you will use in the Lab will have a direct impact on the development of your plants and the vitality of the microbes that live in the hydroponic towers or the soil. So it is imperative that you understand and control the quality of your water to maintain optimal growing conditions.

Create perfect water from tap water. Start with a benchmark for the variety you are growing including a target nutrient level and pH level.

Using a 5-gallon bucket, determine the exact amounts for ascorbic acid, pH UP, and nutrients to create perfectly balanced water for the variety being grown. Record the master formula and use it to top off hydro as needed.
