To grow one million heads of lettuce using conventional agriculture methods in the US requires either 16 acres of land in the Northern states, 8 acres of land in the Southern states, or .9 acres in a traditional hydroponic greenhouse operation. Vancouver-based Valcent Products Inc. (OTCBB: VCTZF) claims that it can beat those numbers handily and produce the same amount of lettuce sustainably on just .16 acres with its patented hydroponic vertical growing system, VertiCrop™.
Seedstock Digest: Hydroponic Greenhouses Atop Super Markets, An Aeroponic System in a Grade School Classroom, Rooftop Aquaponics and more!June 16, 2011 | Robert Puro
It’s Urban ‘Ponic Wednesday at Seedstock and that means we are featuring articles that we wrote on urban agriculture startups that are making use of hydroponic, aeroponic and aquaponic systems. So check them out and get your ‘Ponic on!
From the creators of the Science Barge, the floating hydroponic greenhouse project supporting sustainable food production and powered 100% by renewable energy, comes a new company that builds, designs, finances, and operates hydroponic greenhouse farms on supermarket rooftops. It’s called BrightFarms. By growing produce on site, the company enables grocery retailers to alter their produce supply chain in a way that improves the planet and their profits.
Chances are, if you’ve ever looked into aquaponic systems, the sustainable food production systems that combine aquaculture (raising aquatic animals such as fish, crustaceans, or crayfish in a controlled environment) with hydroponics (soilless plant cultivation in water), you have probably heard of Nelson and Pade, Inc.
Nelson and Pade, Inc. is literally synonymous with aquaponics. Try googling the term ‘aquaponics,’ or better yet, enter http://www.aquaponics.com/ into your browser, and there you will find the company. It has owned the url since 1996.
The idea for TerraSphere Systems’ vertical farming technology all started with a few marijuana plants.
In fact, Nick Brusatore, Co-Founder and Inventor of TerraSphere Systems, began developing his unique hydroponic technology system for medical marijuana cultivation in Canada (Canada began offering medical marijuana to eligible patients in 2003).
After working with their hydroponic technology for a while, Brusatore and his partner William Gildea began to think about population growth and quickly perceived the wider agricultural marketplace opportunities for their product to address future food shortages.
