Inert - chemically non-reactive; inert growing mediums make it easy to control the chemistry of the nutrient solution,
Intensity - the magnitude of light energy per unit: Intensity diminishes the farther away from the source.

Any inert aggregate material can be used for mulching. Coloured bricks or broken glass are currently a popular choice, as are river pebbles, but these are now difficult to source. Scoria and marble chips can look dramatic but are quite expensive.
A good bag has little if any inert matter: Inert matter is nothing more than filler and although it is not harmful, it can take the space of good seeds.
Germination rate should be no lower than 75%.
Aggregate systems use some form of inert material to support and surround plant roots. The most common materials used are rockwool, clay pebbles, gravel, perlite, vermiculite, sand, or foam chips.
Avoid commercial products that contain inert ingredients. Manufacturers are not required to reveal what these inert ingredients are. Inert ingredients have included such chemicals as: carbon tetrachloride, chloroform, and chloroethane.
"We've been trained to think that soil is an inert thing that holds the plants up, so we can put fertilizer on them," says Lovejoy.
Rockwool is an inorganic, sterile, inert growing medium made from a combination of basalt rock, limestone, and silica. It's available in various-sized propagating blocks, wrapped cubes, and large slabs.
Potting soil is usually a sterilized, lightweight, inert medium in which to grow plants. Adding a bit of garden soil or compost provides naturally occurring minerals for optimal plant growth.
Often used in the rooting of cuttings as it is both inert and sterile. Petal A specialized leaf that surrounds the reproductive parts of a flower. Often colored to attract pollinating insects. pH A symbol for the acid-alkaline balance of the soil.
Also listed is the amount of crop seed, weed seed, and inert matter contained in the bag. You want as little crop seed and weed seed as possible in a bag of seed. Less than 1% of either is recommended.
For small areas (less than 2,000 square feet), mix seed with sand or an inert material, such as peat moss or vermiculite, that has been slightly dampened. For a 1,000-square-foot area, use a bucket that's about the size of a bushel.
There's just something so astounding about a small inert bulb producing such a magnificent flower in a relatively short amount of time.
Hydroponic gardening means to grow plants without soil in inert mediums like water, gravel, sand, perlite and rockwool.
The manufacturers are not legally required to disclose the inert ingredients, which can include harmful quantities of heavy metals.
Instead of soil for root growth, hydroponically grown plants need a porous but stable and inert material. Different materials can work, depending on the situation.
The heat of vegetative decomposition renders most pests and weed seeds inert, leaving you with rich organic compost that can help your garden grow.
PELLETED SEEDS: Seeds that have been coated with an inert material to make the handling of the seed easier
PENDANT: Hanging.
PERENNIAL: A plant which will live for three years or more under normal conditions.
Using chemicals in the ground might solve some temporary problems, but when you add chemicals to your soil, you are just adding to the global problem of making the soil inert and causing erosion and pollution of our ground water.
In this example, the remaining 64% of the fertilizer is comprised of inert matter
Definition as written by Terry:
Remembering which nutrient does what is easy, if you'll remember this simple phrase: "up, down, all around" ...
Stake perennials as much as possible in the vigorous days of spring, so when summer's inertia strikes, there will be less work to do. While staking is a routine, inconvenient chore, it is done most successfully if it appears not to be done at all.
Actually plants can be grown in mineral nutrients or they can be grown in an inert mixture such as sand or perlite, as long as the liquid minerals get to the plants feeding system it doesn't matter.
composts at about a 25 per cent by volume ratio, and being inert have no affect upon
the acidity, alkalinity or nutrient content of the compost. However, they do enable ...
Golden Harvest Organics - Golden Harvest Natural Feritlizer is a completely natural product that contains no inert ingredients and is eco friendly. Natural gardening solutions, organic products for you of all kinds! ...
And turn it from a rich entity teeming with microorganisms insects and other life forms, into an inert growing medium that exists mainly to anchor the plants' roots, and that provides little or no nutrition in its own right.
However today the term is more broadly used and can refer to growing in clay pellets, sand or just about any inert substance. The phrase "passive hydroponics" refers to Hydroculture. See Aeroponics. See Wikipedia article on Hydroponics.
In other words, a 50-pound bag of 10-10-10 has 5 pounds each of N, P2O5 and K2O. But that accounts for only 15 pounds out of a 50-pound bag. The rest is either other salts or inert fillers, such as sand, perlite or other materials.
