    Windowfarmers R&D-I-Y: An Open Source Community Developing Hydroponic Edible Gardens For Urban Windows.

    Windowfarms let you grow food year-round inside while maximizing space. They are vertical food-growing gardens that use a dirt-free technique called hydroponics. You can buy a kit or build your own using low-impact or recycled local materials. Having a windowfarm is more about the activity and experience of windowfarming, these are living systems, not just a pretty thing to look at.

    This site is the online community of windowfarmers around the world. Together, we are continually getting better at growing food in the local conditions of our own homes. We are contributing to the “green revolution” as non-experts. We call it R&D-I-Y, or Research & Develop It Yourself. We use this site to collaborate on evolving designs for these vertical hydroponic systems– proposing experiments, testing techniques, and developing a shared knowledge base around the many variables involved in building and maintaining a farm inside a city apartment. Welcome!

    An online community of 40,561 Windowfarmers from around the world. Newest posts:

    The pulser pump (airlift pump and trompe working together) has been researched in Loughborough university. PDF available

    June 14, 2013 in Education, energy consumption, environmental impact, R&D-I-Y, Water flow by Brian White

    I have a link to a download for the pdf file in the video description.   Please note that I have not looked in any detail at the file because I only got it yesterday morning.  BUT it probably contains relevant info or leads on how to make better low pressure airlift pumps.    So [...]

    New photos after 3 months

    June 14, 2013 in Uncategorized by Tad

    After a few months, I’ve found the following: The plants grow best with the pump running constantly. It not a constant stream of water since it mostly bubbles, but a constant drip. The reservoir is too small. It should at least be twice the size. If the water is too low, it won’t pump correctly [...]

    Adding some color…First window farm

    June 12, 2013 in How-Tos, made from scratch (without a kit), Materials and Resources, posts with pitcures! by Lindsey Schiller

    An engineering student developed this version of the window farm using 2 L soda bottles, for our model greenhouse in Boulder, Colorado. I wanted to make it both attractive and functional, so I – along with help  - spray painted the bottles. For more info on the how-to mechanics of the system, you can message [...]

    The Nuts and Bolts

    May 24, 2013 in Completed Window Farms, made from scratch (without a kit), Materials and Resources, Plants, pumps, R&D-I-Y, Starting Seeds, Uncategorized, Version 3.0 Modular Airlift Columns, Water flow by Matt

    Here, I am going to highlight the nitty-gritty parts of the operation. For the resevoir exit, I drilled a hole in a rubbermaid and secured a small piece of tubing into it with some waterproof caulk. This small piece of tubing is then connected to the rest of the line by that funny white connecter [...]

    Nutrient starter pack… plus some pH adjustment

    May 24, 2013 in Nutrients, Plants, Seeking Advice by Matt

    Here is the starter pack of nutrients I was reccomended by the hydroponic store. So far, I am rather happy with how this is going. As a control, my hydroponic cumcombers inside have done much better than my traditionally planted cucombers growing outside. This stuff definitely works! The same can be said for my tomatoes, and [...]

    Final setup

    May 19, 2013 in Uncategorized by Kok

    Hi,   Some weeks past after my first tests and all is growing very good. After the first setup I tested a few things and end up with this setup what I think is not bad. I painted all bottles white so it reflects the sun light and not warming my water too much and [...]

    May 2013 update: New fish tank reservoir….

    May 18, 2013 in Being a good member of this community, Completed Window Farms, Education, Featured Post, posts with pitcures!, R&D-I-Y, Seeking Advice, Version 1.0 Reservoir System, Windowfarms Project News by Jeremy

    Hey fellow window farmers! I switched out my old gallon green tea jug with this…a football fish tank I’ve had since I was a little kid. There’s a built in filter system too, so hopefully that will help reduce the algae build up. Let me know what you all think!

    i wanted to remove plastic from the equation so this is built entirely from fda approved materials. i used food grade silicone tubing in black to reduce algae, food grade silicone sealant to connect tubing to bottom pots, terracotta pots that i sealed with beeswax, gaskets made from cork coasters, net pots made from foodgrade [...]
