The Halide lights have a very balanced spectrum and are excellent for vegetative growth or leafy plants like lettuce and basil. The Halide lights produce between 65-115 lumens per watt which is a measure of the efficiency of the bulb, or how much light you are producing for the amount of electricity you are using. The Sodium lights produce light that is very bright and concentrated on the yellow to red side of the color spectrum.

In our controlled trials, we found that High Pressure Sodium (versus Metal Halide) when used for an entire crop cycle, slightly but noticeably out performed Metal Halide. We have also found that High Pressure Sodium gives a marginally better yield if it used for the bloom phase and the Metal Halide performs slightly better during growth. Our results would not justify purchasing both the lights for growth and bloom but this may not be the case with all species and strains.

There are a couple of reasons growers switch between bulbs during different stages of plant growth. First, Sodium bulbs can make some plants grow "leggy" and stretched out due to the high yellow to red spectrum they give off. Halide bulbs tend to keep plants "tighter", with less space between internodes.

The difference between these two types of HID (High Intensity Discharge) lights is the color spectrum that is emitted from each. The High Pressure Sodium bulb emits light that is concentrated in the red to yellow side of the spectrum and are weak in the blue-violet end. While the Metal Halide bulb emits light that is very balanced and contains all the energy peaks at wavelengths of the visible spectrum.

Yes you can. You will need to change out the ballast, capacitor, ignitor and lamp. However, there are several cautions that must be taken: the metal halide wattage must be within the fixture limitations; the socket position may need adjustment; the reflector may be different or the ballast strapping may not fit properly. Please contact the factory for a specific product.

First, what type of natural light are you working with? When supplementing natural sunlight, use a High Pressure Sodium bulb to extend daylight in the early spring and fall. You can also use them on low light cloudy days. When no natural light is available at all, a Metal Halide bulb is most frequently used, , which is a very wide spectrum bulb perfect for indoor growing. Halide lights are excellent for vegetative growth for leafy plants like lettuce and basil.

Metal Halide lamps should be changed at least every 6 to 12 months if you're burning them 18 hours per day. High Pressure Sodium bulbs, burned at 12 hours per day, will last between 6 months and a year and a half depending on the bulb.

Although both types of lighting systems appear very similar, the main difference becomes readily apparent when you turn them on. A Halide system emits a balanced white light similar to the spectrum of sunlight. This type of light promotes vegetative growth. A Sodium system emits a light spectrum and gives off a warmer colored light. This type of light helps stimulate a plant to produce flowers and fruit.

Sodium ascorbate is an antioxidant that prevents ranciding. Sodium ascorbate also stabilises colour so that the meat keeps its natural colour longer.

We now know that a single concentration of sodium - 90 meq/L - is suitable for all ages and most degrees of severity (except high output cholera in adults). This is the most robust level. Packet combined chemicals allow for greater safety, as bazaar salt is likely to be coarse and sucrose may be adulterated. Bazaar-bought chemicals may be more often available (not always: shortages of salt and sugar occur in the poorest countries), or perhaps cheaper.

The ImagePro will physically fit into the Altman Shakespeare, ETC Source Four , Selecon Pacific, and the Strand SL. At the time of this writing, the following options had been tested: Altman Shakespeare CDM 150 – Fine. Normal lifespan of slide. ETC Source Four HID 150 – Fine. Slide lifepsan increase by approx 20%. ETC Source Four MSD 250 – Too hot. Slides burns out. Selecon Pacific MSR 575 – Fine. Normal lifespan of slide. Selecon Pacific 80v - Fine. Normal lifespan of slide.

Yes. Any CUNO water softener may use either Potassium or Sodium Chloride as a re-generant without changing settings. This is of special interest to anyone on a sodium-free or low sodium diet.

Sodium PCA or NaPCA functions in human skin as a humectant, a substance that attracts water. Without enough NaPCA in the skin, the moisture level will drop and skin will dry out. Without enough moisture, nutrients cannot be properly delivered to the skin cells. NaPCA is the most powerful, non-toxic humectant known, and the most important humectant in the skin. - top -

Amy's Kitchen tries to minimize the amount of fat and sodium in all our products, but we also want the products to taste the very best they can to the large majority of Amy's customers. So, although some of Amy's products are acceptable to many who are generally trying to cut down on fat and sodium, they are not intended specifically as medical foods.

When mixed with water, sodium bisulfite is a liquid form of sulfur. Using sulfur to pretreat foods is rooted much further back into dehydrating history than most of the other methods available today. It is the most effective and least expensive anti-oxidant. Use only a food-safe grade of sodium bisulfite that is made especially for dehydration. Excalibur's Sodium Bisulfite is available here and wherever dehydrators are sold.

Sodium is the 6th most abundant element on earth. The most common sodium-containing mineral is salt (sodium chloride). Salt causes the saltiness of the oceans. It is also a normal component of the body and adequate levels of salt are required for good health. Since the sodium in salt may negatively affect your health, salt in foods and drinks is generally referred to as ‘sodium’. Sodium dissolves easily in water and groundwater always contains it at some level.

No we do not use menadione sodium bisulfate in any of our products. We eliminated the use of menadione sodium bisulfate in the winter of 2005. If you currently have a bag with menadione sodium bisulfate listed in the ingredients with a best before date after December 2006 it does not contain menadione sodium bisulfate, we are currently using up an existing stock of old bags.
