  • How to Grow Potatoes

    Having a garden is both a relaxing hobby and a great source of fresh food, if you plant the right things. Sometimes we overlook simple plants like potatoes, even though they’re actually pretty easy to grow, and are a delicious source of nutrients. I want to help you understand everything you need to know about how to grow potatoes in your own home garden.

    This is an all-inclusive guide that will deal with every aspect of potatoes, from the planting to harvesting, to get you started on the path to growing your own potatoes.

  • These folks feed their family with a garden in their swimming pool

    The substainable garden pool project

    Published on Jul 28, 2016 by Delia on 3tags.org
    "When Dennis and Danielle McClung bought a foreclosed home in Mesa, Ariz., in 2009, their new yard featured a broken, empty swimming pool. Instead of spending a small fortune to repair and fill it, Dennis had a far more prescient idea: He built a plastic cap over it and started growing things inside.

    Thus, with help from family and friends and a ton of internet research, Garden Pool was born. What was once a yawning cement hole was transformed into an incredibly prolific closed-loop ecosystem, growing everything from broccoli and sweet potatoes to sorghum and wheat, with chickens, tilapia, algae, and duckweed all interacting symbiotically to provide enough food to feed a family of five.

    Within a year, Garden Pool had slashed up to three-quarters of the McClungs’ monthly grocery bill (they still buy things like cooking oil and coffee and, well, one can’t eat tilapia every day). Within five years, it’d spawned an active community of Garden Pool advocates – and Garden Pools – across the country and the world."

    Create the Perfect Vegetative Period Indoors — 4 Minute Guide


    Published on May 26, 2016 by Everest Fernandez
    We're talking about the perfect vegetative period here—that is, building stems and leaves—rather than producing flawless fruits. However, every bumper harvest begins with a stress-free, vigorous vegetative period—we detail how to create the ideal growing environment indoors for your short-cycle, heavy fruiting annual plants.

    30 17.48 8.74 4.37 2.91 2.19 1.75 1.45
    Select the CO2... flow rate and minutes of operation that will give you the proper ppm of CO2 for your growing area. Next, find the values that correspond to these two settings in the Carbon Dioxide Tank Cycles Chart and multiply that number by your tank size.

    Example: From the Carbon Dioxide Flow Chart for Emitter Systems you determine that you need 15 Cu.Ft./Hr of CO2 at 6 minutes of "On" time. From the chart above, the cross-reference settings is 5.83. To determine the maximum number of cycles your tank will accommodate, multiply you tank weight* by 5.83. If you had a 20lb tank, the total number of cycles possible from a full tank would be 117 (20 x 5.83).

    * Tank weight refers to the actual weight of liquid CO2 in the cylinder and not the weight of the empty tank. A standard 20 lb. tank therefore, has 20 lbs. of liquid CO2 in the cylinder. Some standard tank sizes are 10, 20, 35 and 50 pounds. Even if you do not have a standard size tank, this method will work to determine the maximum number of cycles possible.

    Lumens are for humans: plants see things different

    Published on May 3, 2016 by GavitaHolland
    Lumens and lux are used to quantify light according to the spectral sensitivity of the human eye, which is pretty limited. When quantifying light for plants we use different units. Just as we have lumens and lux, for plant light we use PPF and PPFD, based on the PAR spectrum.
