BN-LINK Timer

Last of the 5 grow light timers on our list today, is this 2-1 digital timer and power outlet from BN-LINK (Century).

This is the most expensive timer we’ve featured and could be thought of as a premium grow light timer in that respect.

Design and build wise though, it is just above your average for a mechanical grow light timer, and like many timers will be manufactured in China.

What makes it stand out above the crowd is the 4 always-on power outlets that are integrated into the design.

This 2-1 feature is something I’m surprised more manufacturers have not decided to implement into their designs, as it really is a very useful feature.

What are Grow Light Timers?

A grow light timer is a device that controls the amount of light plants receive in a grow room or grow tent. It allows growers to set a specific time for the grow lights to turn on and off automatically. Grow light timers can be digital or mechanical, and the settings can also be customized to match the specific needs of each grower.

How do Grow Light Timers Work?

Grow light timers work by turning on and off the lights at pre-determined intervals. When it is time for the lights to turn on, the timer supplies power to the grow light. When it is time for the lights to turn off, the timer cuts off power to the lights. This action can also be timed and set to different intervals, depending on the needs of the plants being grown.

Digital Grow Light Timers versus Mechanical Grow Light Timers

Digital grow light timers are a more advanced version of the mechanical grow light timer. Digital timers are usually more precise in terms of setting a specific time for the lights to turn on and off. They also offer more flexibility compared to mechanical timers. For instance, a digital timer can be programmed to turn on and off the lights at any time or for specific intervals of time, such as 15 or 30 minutes interval.

On the other hand, mechanical timers have the advantage of being cheaper and easier to set up. A mechanical timer is a plug-and-play device that only requires plugging the grow light into the timer and setting up a simple dial to control the on and off cycles.

Benefits of Using Grow Light Timers for Growing Cannabis

1. Improved yields: Cannabis plants require a certain amount of light to grow healthy and produce high yields. With a grow light timer, growers can provide the plants with the exact amount of light they need. This ensures that the plants receive optimal light exposure, which in turn leads to improved yields.

2. Energy saving: Grow light timers allow growers to control the amount of electricity used in the grow setup. Setting up a grow light timer reduces the risk of leaving the lights on for too long and wasting power. This means that growers can save money on their energy bills while creating a safer environment for the plants.

3. Automated control: Grow light timers offer automated control over the lighting system. This is especially useful for growers who are busy and may not have time to monitor the plants throughout the day. With a grow light timer, growers can set the lighting cycle to match the specific requirements of the plants being grown.

4. Simulates a natural light cycle: Using a grow light timer allows growers to mimic the natural light cycle. This is especially important during the flowering stage, which requires a specific light cycle to trigger the plant to grow buds. A grow light timer ensures that the plants receive the right amount of light exposure and creates an environment that mimics a natural light cycle.

Factors to Consider When Choosing a Grow Light Timer

1. Capacity: The capacity of the grow light timer is one of the most important factors to consider. Growers should consider the number of grow lights they intend to use and ensure that the grow light timer can accommodate the required number of lights.

2. Type of grow light: The type of grow light being used is also important when choosing a grow light timer. Some grow light timers are more suited to specific grow lights. Growers should ensure that the timer they choose is compatible with the grow light they are using.

3. Ease of use: Grow light timers can be either digital or mechanical. Digital timers may be more complex, and some growers may find them challenging to use. Mechanical timers, on the other hand, are more straightforward and easier to use.

4. Price: Grow light timers come in different price ranges. Growers should consider their budget and choose a timer that offers the features they require within their price range.

Recap

One of the essential tools in any cannabis cultivation setup is the grow light timer. A grow light timer can help improve yields, save energy, and provide the perfect amount of light for your plants. They ensure that the plants receive optimal light exposure, which leads to improved yields and energy saving. Choosing the right grow light timer is essential for a successful grow setup. With a grow light timer, growers can enjoy a smooth and efficient cannabis cultivation process.
