Algae grow fast with sunlight, water, carbon dioxide, and nutrients, typically reaching peak growth in 30 days. They use photosynthesis, like plants, to create their food and are commonly farmed in outdoor ponds. Algae have 20-80% oil content, which is useful for making biodiesel, and their production is considered economical. Over 700 algal species exist, some of which are edible, and they all contribute to oxygen production through photosynthesis. In the right conditions, algae reproduce quickly and can be used for various purposes after harvesting.
Conditions for Growth
For optimal growth, algae require 10-15 hours of 60-80°F sunlight daily. They spread most during the summer when they have access to abundant nutrients and light. In aquariums, algae typically take 15-30 days after setup to appear. However, excess nutrients and light can lead to unwanted aquarium algae growth, which can be controlled using scrapers or towels.
Cultivating Algae
A simple container with water and nutrients can grow small amounts of algae. To boost growth, add sugar and ensure the algae are carefully shaken and exposed to light daily. For enthusiasts, it’s possible to create an algae incubator for under $35. Additionally, you can make algae powder by grinding the algae and mixing it with water and citric acid.
