Hydroponics: Can Blue Green Algae Be Used as a Substitute Hydroponics Solution and Sustain Plant Growth?

Overview

Objectives/Goals The objective was to determine if Blue-Green Algae could be used as a substitute hydroponics solution, which could successfully sustain plant growth. Methods/Materials Step #1 Build hydroponics apparatus. Step #2 Growing several types of Blue-Green Algae to compare with hydroponics solution, bacteria based bio formula, & aquaponics solution. Step #3 Geminating seeds Step #4 Measure and compare the height and weight of several plants grown in the different kinds of plant growing formulas. Results The plants that grew in a solution of Blue-Green were an average 20 percent taller and weighed 32 percent heavier than the plants that grew in formulated hydroponics formula. Conclusions/Discussion The particular concentration of living Blue-Green that I grew in beakers provided a more nutritious growing solution than the optimum concentration of EcoGrow. The ecogrow was designed for optimum plant growth. I believe the Blue-Green algae which collects energy directly from the sun, has a lot of important vitamins, minerals or other nutritious components that are valuable for plant growth.
