Sustainable fish food for aquaponics; Bioponic nutrient cycling

What makes bioponics uniquely different that aquaponics is that while it supports fish, it does not require fish to fertlize the beds. A balanced system is like an ecosystem, supporting all varieties of life but not depending on one element to support the operation. Continue reading


Algae as a fish food and pH modifier.

Algae creates alkalinity in the water. In fact, when we take a side stream of aquaponic water to our cells of aquaponics the pH rises up to range of 9-10 very quickly. We also raise algae with human urine, but if using as aquaponic fish food and ultimately for plants, care must be taken that … Continue reading

Peeponics in Georgia, Ecosan Urine Fertilizer in India, Urine Therapy Elsewhere

From around the world we are learning more and more how others are creating their own models of sustainability. Hydroponics would benefit tremendously to have a homemade source of fertlizer. The notion of organic can actually be elevated to a second generation, requiring that food consumed by the source of the urine was also organic. … Continue reading

Bioponics: Looking back to see forward

We have much to learn from peoples of “underdeveloped” countries around the world. In remote farming villages of China, fish ponds are managed with great efficiency, entirely eliminating the costs and complications seen with industrialized aquaculture. That is happening because their traditional utilizes a process of “nutrient cycling”. To fertilize their ponds and raise lots of fish, Asian villagers plant … Continue reading

Urine composition for determining benefits as fertilizer alternative.

Here is an overview of what minerals and elements are found in human urine. This is useful for determining urine requirements for volumes of water base total plants and plant needs. Algosolar will soon post a calculator to help calculate ratios. Nearly all of these substances are utilized by all other living species, in one … Continue reading

Locally produced fish food: Grow your own plankton and zooplankton.

Here is a simple project for raising algae that is practical, as a tabletop exercise, for high school education labs. Growing in this fashion is similar to the process of high tech bioreactors and various tube systems commonly used in the biotech industry. Researchers feed algae with CO2 from combusted exhaust emissions, a method which holds great promise … Continue reading

Algae Video Overview; Russel Chapman

It’s a bit of a long intro so if you fast forward 5.5 minutes you’ll cut to the chase. This is an informative overview of algae; its origin, structure and phylogy. Delivered by Russel Chapman at Scripps Oceanograpy along wiht his his humorous affection for algal species. It’s a bit of a long intro so if you fast forward 5.5 minutes … Continue reading

Taking lessons from Earth’s most successful living organism, Algae.

Sometimes I just don’t get why it is our most natural abundant resources have been ignored and replaced with hyped-up store-bought empty substitutes? Algae is awesome! But only since the latest rush towards biofuel has it gained appreciation in green technology as a source of fat and oil for energy production. While there remains a considerable energy-requiring process to convert … Continue reading

Vermicompost and VermaPonics; Worms like trash, Fish like Worms, Plants like Worm Poop. Where Do Humans Fit In? Well Don’t Be Surprised…

See the full gallery on Posterous As seen produced here at Growing Power, worms and worm castings are a budding farm industry. This is a practical way to turn waste into worms and compostings into plant fertilizer. Waste is free, castings and live worms make a profitable return. At OTGE we like worms as fish … Continue reading

Wood Ash and Human Urine Study Conclusion; Pee on it and feed it to your plants, daily.

Two recent studies, published in the J. Agric. Food Chem., showed that when wood ash was combined with human urine and used as fertilizer the results outperformed chemical fertilizers.  Greenhouse tomatoes fertilized with urine, with urine and ash compared to those fertilized with 135 kg of N/ha as a mineral fertilizer. Results showed that urine … Continue reading
