What You Need To Know About Full Spectrum LEDs

Purchasing an HPS light can help anyone grow several plants inside the house. This is ideal during the early stages of seedling growth because it helps ensure a healthy and stocky build on the plants. In using the spectrum of an HPS light, a gardener should take note that each and every plant has its own needs. Thus, seedlings should be exposed to a particular spectrum according to their lighting necessity. Usually, plants found in shady areas don’t need as much light compared to plants located in dry areas. Additionally, flowering plants need a much more intense light source since they need it for producing flowers or fruits.

There are many types of indoor grow lights, and one of them is the HPS type. Today, High Pressure Sodium bulbs are often used by gardeners since they are newer as compared to the other types of lights. Also, an HPS uses less electricity, so you’ll be able to save on your electric bills. If you are purchasing this for your plants, a 1000 watt HID grow light is great for indoor gardens. Also, you’ll have to check for other factors like the budget, ventilation, area, and the plant type used. In budgeting for your indoor lights, make sure to check on the average prices on the market. Usually, an HPS costs more than other types of grow lights, but in the long run, it’s much more beneficial for your plants.

What Are The Advantages Of HPS Bulbs?

Aside from its low electricity usage, an HPS light has a great luminous efficiency. When you compare this to other types of bulbs, an HPS bulb produces more visible light. They are also very durable than fluorescents and incandescent lights, and they can even last up to years of constant usage. It’s because HPS lights are made without gas or vacuum components. These are also heat-efficient, so they don’t emit damaging heat waves to the plants nearby.

HPS Grow Light Tips For Maximization

For indoor gardeners, maximizing their HPS light is a great practice since it can save a lot of money and energy in the long run. Here are six tips that can help in optimizing your HPS light usage:

1. Don’t Overwater Your Plants

It’s always a common mistake for indoor gardeners to overwater their plants. While this is fine when you are using a different type of lighting system, using an HPS light means that the drying process takes more time since it emits less heat than the rest of the grow lights. You wouldn’t want your plants to get rotten, right?

2. Increase The Area Temperature

Because HPS bulbs don’t generate as much heat as the other types of light, you should increase the area temperature. It’s essential for the plants to be rooted on a solid soil and not on the watery ground.

3. Follow The Recommended HPS Placement

The placement of the HPS light is very vital if you want to have a successful yield. While placing your bulb on a higher distance increases the area of light coverage, the heat intensity also becomes weaker. On the other hand, if the HPS light is too close, the harsh proximity of the light can damage and hamper the growth of the plants. It’s advisable that you follow the recommended mounting distance of the HPS lights. While it’s safer to place them in the middle, following the specific mounting distance is much more preferred.

4. Install Several HPS Units

A single HPS light is not enough if you have many seeds to plant. Why not buy several lights and install them according to their recommended specifications. To maximize the lights, place them at a strategic location wherein the beam lights overlap with each other. In this way, you can double the heat intensity and plant more seeds in the covered area.

5. Follow a Light Cycle

Plants always follow a light cycle whether they are placed outside or inside the house. However, indoor plants don’t follow a natural cycle since they are constantly shaded inside the house. Thus, indoor gardeners should learn about manipulating these cycles. Because you have the power to control the hours of the light and dark cycles, you can add blackout curtains or supplemental lighting to your garden as well. This means that you can avoid any unwanted light outside the house with the blackout curtains, or prolong the light cycle during winters with a supplemental lighting. When you think about it, having an indoor garden is easier because you can manipulate factors that aren’t controllable outside the house.

6. Create Light Recipes

The possibilities are endless with an HPS light. It’s amazing that we are already at a time wherein the color spectrum needed for a plant to grow can already be crafted. If you are planning on an HPS grow light, make sure that it comes with a full spectrum or buy one that is in tune with what you desire.

HPS lights are considered to be one of the most valued indoor growing lights. It’s not only known for its effectivity, but it’s also known for its durability in the long run. While an HPS light can already stand alone, following these tips can definitely maximize the full potential of this fantastic light.
