Open Pollinated and Heirloom Variety Vegetable Seeds

January 22nd, 2012 by admin No comments »

Over the past few years there is a large movement towards growing your own fruits, vegetables and herbs from seeds. The top three reasons people gave in a recent study conducted by the National Gardening Association, were to put fresh produce on the table, save some money and to know that what they were growing was safe.

Who can argue about all three reasons? Can there be anything in the store that is fresher than walking out of your back door, picking a tomato off the vine and then eating it right at that moment? I don’t believe so. As for saving money, the cost of a single vegetable seed is less than a hundredth of a penny. Yes that is one, one hundredth of a penny. Now of course you still need to water and tend to the plant, but in a recent USDA study, one tomato seed can produce over $50 worth of tomatoes. That’s a pretty good return.

When it comes to the safety of your vegetables, growing your own puts you in control of it. Unlike produce in stores, that are harvested in places you didn’t even know existed, you get control what goes into your soil and whether or not you want to treat your plants with a fertilizer. In other words, you make all of the decisions. That’s freedom to me.

This surge, and for these reasons, has lead to another push toward something. A variety of seeds that make vegetable gardeners feel safe when they plant them. They are open pollinated and heirloom varieties. Most of the time they can go hand in hand, but that is not always the case.

Open pollinated seeds are ones that have pollinated naturally. This type of pollination occurs when something helps pollinate the plants without “human” intervention. For example, the wind could be a source of pollination (this is also called Abiotic pollination), or some organism, such as a bee (Biotic pollination). The fruit of seeds that have been open pollinated will vary in size and shape. Unlike what you see in the store, all of your tomatoes won’t be the same bright red color or shape, but the ones from your garden will taste a heck of a lot better. A huge benefit of using seeds that are open pollinated is that you can save seeds from the fruit of the plants that you grow and get the same plant variety the following season (after you have dried out the seeds). That leads us to heirloom.

As the name heirloom implies, it is simply a variety that has been passed down from one generation to the next. As you can see, open pollinated and heirloom can go hand in hand, however there are times when many gardeners hand pollinate their plants if it seems that natural open methods simply aren’t working. That doesn’t mean you can’t pass down the seeds from your heirlooms, it just means they weren’t open pollinated.

As a side note there are two terms that get thrown in this mix that many new vegetable gardeners misunderstand. Open pollinated heirloom variety does not equate to organic. For a seed to be organic it has to meet the criteria of the USDA’s National Organic Program guidelines. Furthermore, a hybrid vegetable does not mean that a plant has been genetically modified. A hybrid is a cross between two plants to produce an offspring that has characteristics of both the parent plants. However the seeds of a hybrid child (referred to as F1) will not necessarily produce the same exact plant from which it came.

600 Watt HPS Grow Light

What does HPS stand for? HPS stands for high pressure sodium. Sodium ions will start to emit light when electricity goes through the molecules. Under pressure, the light gets brighter and closer to true light in color. It is a popular option for those who want to light the outdoors at night. It provides a gentle light that still illuminates the area and provides security without being jarring to the eyes at night. The longevity of the bulbs is another reason why different entities use these lamps in outdoor fixtures. They are very efficient and put out a great deal of light. A 600 watt HPS grow light will give a great deal of light without using a great deal of energy.

What are the components of an HPS grow light system? There are four basic components of a grow light system. The first piece is the most obvious. The bulb emits the light. A good example is a 600 watt HPS grow light. This bulb requires a reflector that will focus the light downwards towards the plants. The third component is a ballast. A ballast helps to reduce the amperage of the electricity and give the lamp a steady amount of energy. The final piece of the puzzle is the connection to the electricity. Most have a plug while others require a dedicated connection to electricity.

Why choose an HPS system over other options in these type of set ups? There are a number of benefits to using an HPS. It has a long life when compared to fluorescent and metal halide lights. For example, you can expect up to 24,000 hours of use out of a typical 600 watt HPS grow light. For a similar fluorescent the life expectancy is 10,000 hours. For a metal halide, it is 15,000 hours. These bulbs provide more lumens than many other lamps you can use. They are great as supplemental light in a greenhouse over the winter.

What should you expect from an HPS unit? A high pressure sodium fixture should be compact. The amount of lumens brought off per watt should be higher than you would find in similar metal halide or fluorescent lamps. A typical 600 watt HPS grow light should give you enough output of light to cover between 15 and 20 square foot of plants. With the longevity of the bulbs, you should expect the bulb to last for at least a year of constant use or two seasons of seed starting.
