Saltwater also affects plants by inhibiting their growth and photosynthetic capabilities. Only add water if they are getting dry. I wasn't sure how long you would continue this project as well. In comparing the results after an average was calculated from each concentration of salt, it was determined that the 8 and 6 ounce salt water concentrations harmed the plant growth the most. The amount of salt in soil is a major problem for growers. We did that one time too, and none of them grew. https://www.education.com/science-fair/article/saltwater-effect-grass-plants They had predicted that river water would make the plant grow tallest.

Any seeds appropriate to your area would be fine, including ones that are available at Lowes, Home Depot or any garden store. Farmers sometimes flood their fields to leech out the salt that accumulates in the soil through water evaporation.

Watering plants with hot water "can cause stress to the plant leaf and root systems," Plunkett explains. We also did this experiment with white flowers too! I will pass this along to my daughter, she will be excited to hear about it. Interesting! Since you need to check the bags daily to count the seeds that have germinated, it is easy to also check each bag to see if it needs more water. Make sure the seeds are scattered evenly over the filter. In this experiment, 8 plants will be tested. You might want to look up hydroponic plants. Two of my children did versions of this experiment for our state science fair. Each plant will receive 1 more teaspoon than the previous cup, so it would be increasing.
