There are many answers about student projects on watering plants with
different liquids at MadSci.org. Most liquids other than water will be
harmful to most plants, including bleach, milk, sugared sodas, and
fruit juices. Some liquids may not be too harmful to plants, or
slightly beneficial, such as diet soda, coffee and tea. Plant growth
may also be affected by different types of water (tap water, softened
water, distilled water).
The optimal irrigation solution for plant growth is usually good
quality tap water or a dilute fertilizer solution.
Bleach is a solution of sodium hypochlorite (NaOCl). Search the
internet for a Material Safety Data Sheet on sodium hypochlorite to
find some basic information. Sodium in high concentrations is toxic to
most plants. There is a lot information on the effects of table salt
(sodium chloride) on plants. Search for plant salinity.
