    Soil & Organics: Vermicomposting 101

    We all want to use items that increase our garden’s fertility in the hopes of explosive yields. With that as our aim, there is one item that stands out as a must-have for all soil and soil-less gardens: worm castings. Vermicomposting is the use of worms to break down organic material. Worm castings are the result of their digestion process. This process will give you some of the highest quality castings available and help you create a more technical and successful garden experience without a lot of effort.

    Super Feeding: Do Mycorrhizae Have a Role in Hydroponics?

    Mycorrhizae experts Mike Amaranthus and Josh Eagan give us the low-down on how mycorrhizal fungi behave in a non-soil environment, and how hydroponic growers can use this special root fungus to improve plant quality and yields.

    Mycorrhizal Fungi in Hydroponics – Q&A

    Urban Garden Magazine asks and answers all the questions on using mycorrhizal fungi in a hydroponic growing environment.

    Recirculation Basics – Part 2

    Last issue, Michael Christian discussed the fundamental fluid of a recirculating hydroponic system… water. Without pure clean water (low EC), we are going to be scratching our heads when it comes to troubleshooting problems when they occur. This time, we look at water analysis, maintaining nutrient balance and strategies for managing pH in a recirculating system.

    Expert Eye: Phosphorus

    Phosphorus is one of the ‘big three’ major elements that’s vital to the growth and health of plants. It assists in converting the sun’s energy and other chemicals, such as nitrogen, into usable food for plants. A phosphorus deficiency is definitely something that every indoor grower wants to avoid as it invariably leads to sick-looking, stunted plants that produce smaller, lower quality fruits and flowers. Not good! So is the answer to bigger yields simply to pack on the P? Well, it’s not quite as simple as that, so we asked Geary Coogler from BS Horticulture for some expert advice.

    Recirculation Basics – Part 1

    Michael Christian, an expert consultant to the commercial hydroponics industry, shares his insights into recirculating nutrients effectively to achieve high performance plant growth while conserving water and nutrients.

    Crop Killers

    The Top 10 Mistakes That Drag Your Yields Down: Everest shares some time-honored heuristics to help beginner growers increase the productivity of their indoor gardens.

    Ebb and Flow System (aka Flood and Drain)

    The Ebb and Flow hydroponics system is a very popular method among first time hydroponicists.  It uses a submersible pump in a nutrient reservoir to pump nutrients into an upper tray containing the plants.  The pump is switched on several times a day via a basic timer.  The nutrient solution is pumped up to the [...]

    My Quest for “Bioponics”

    It’s not every day that we here at Urban Garden HQ come across somebody who has discovered a completely new way of growing plants. However, that’s exactly what William Texier from GHE has achieved! It’s called “bioponics” – a marriage of hydroponics and organics. We asked William to share his personal story with us. Here’s what he had to say.

    Maximizing the Nutrient Environment – Part 3

    In the third and final installment of this series, Lawrence Brooke, founder of General Hydroponics, looks at how to introduce beneficial biologicals into a hydroponic growing system.
