Have you been thinking about indoor gardening but your house is not the best environment for plants? Don’t worry too much about it; all you really need is a grow light. If you want your plants to grow well and thrive all year round, you definitely need to invest in a grow light. A grow light is almost equivalent to natural sunlight; it mimics it and provides it with the same intensity and conditions provided by sunlight. It provides it with the full color spectrum needed for your plants at every stage of their development. The best part is that you can adjust the light intensity to best suit your plants at their vegetative and bloom stage.
You may have the best lighting inside your house but without a grow light, your plants won’t grow in a healthy manner. This is because plants absorb and convert energy from natural sunlight to produce enough food for their growth. This process is called photosynthesis, and it’s the only way plants remain green and healthy. It provides enough fuel needed for your plants to develop successfully. A grow light is not natural sunlight, but it’s pretty close to it; it is an artificial source of light and energy that provides the different frequencies in color spectrum needed for your plants to grow and develop successfully.
There are various types, shapes and sizes of grow lights; one of these is the grow light bulb which is very compact and small-sized when compared to the other types. To know more about these other grow light types, read
There are three major types of grow lights; High Pressure Sodium (HPS) lights, Light Emitting Diode (LED) and Fluorescent or CFL lights. Choosing between these types of lights really depends on the type of plants you’re growing.
- High Pressure Sodium or HPS grow light is the most powerful type of grow light. It provides a full light spectrum for your plants at every stage of their growth. It is also quite expensive and may need to be replaced very often because of the decrease in its intensity. It also emits a huge amount of heat energy. If you choose to use this type of grow light, you’ll need to get a cooling fan and the best grow tent ventilation kit to reduce the heat and ensure your plants don’t get burnt.
- Light Emitting Diode or LED grow light is very new in the market. They’ve now become very popular among indoor growers and are used with grow tents. It is one of the best grow light option because it gives off red and blue LEDs which are both necessary for the growth of your plants. Most of them don’t include UV Ultraviolet and IR Infrared, but they produce full spectrum light which is very beneficial for your plants. The upside is that they don’t emit a lot of heat so you may not even need to purchase heavy-duty cooling fans. The only disadvantage is that it’s a bit pricey but definitely worth the investment.
- CFL or Fluorescent grow light is the light commonly used in schools, garages, office buildings and other places. It is also pretty good for plants as it provides the necessary light source needed for their growth, but it doesn’t produce full spectrum light.
Types of Grow Light Bulbs
Just like there are different types of grow lights, there are also many different types of grow light bulbs, a lot of these are electric bulbs developed to facilitate indoor growing. The most common types of grow light bulbs are
Compact Fluorescent Lamps or CFL
CFL grow light bulbs are a pretty good choice for indoor gardening. They are best for small growing spaces and can be used for a limited number of plants.
High Pressure Sodium Light Bulb
High Pressure Sodium or HPS grow lights produce a yellow and red light spectrum and are best used for plants almost at their bloom stage. They are one of the most powerful types of light with very strong light intensity. They are mostly used by large-scale growers to encourage fast growth and large yield.
Metal Halide Grow Light Bulb
This type of grow light is really strong, and it produces a cool blue-green light which is best when growing a large number of plants. This cool light encourages full growth and larger yields, but the disadvantage is the short lifespan.
Light Emitting Diode or LED Grow Light Bulb
LED grow light bulbs are very new among indoor growers. They produce red and blue lights and have a higher luminosity when compared to fluorescent grow light bulbs. They produce way less heat and don’t consume a lot of electricity. They also have a very long lifespan.
Grow Lights Tips and Tricks
To get the best out of your grow light, here are a few guidelines you need to follow
- Turn Off the Light Very Often
: This is very important when using grow lights. As much as plants need light to grow well, keeping the light on all day may cause some problems. Your plants need to rest for a while to remain strong. The time duration for leaving the grow lights on really depends on the type of plants, but it is advisable to leave it on for about 6 – 8 hours daily. This way, you are imitating day and night cycles. You can get a timer to make it easier to automatically turn the lights off and on.
- Don’t Overwater
: This is a common issue among indoor gardeners. Watering your plants is very good, but overwatering may cause more harm than good. Watering your plants should depend on the type of grow light you are using. If you are using HPS lights, you should water your plants more often because these lights produce a lot of heat, causing your plants to dry up quickly. LED grow lights, on the other hand, don’t require a lot of watering. These lights don’t produce a lot of heat, so you don’t have to water very often.
- Install Multiple LED Grow Lights
: If you choose to buy LED grow lights and plan to grow many plants in your grow room, it is advisable to mount more than one LED grow light. LED grow lights are usually focused on one section of the room; this means some plants may not get enough light. To ensure maximum light dispersal, invest in more than one grow light, especially if you purchase a grow light bulb. This is to ensure that the light is spread evenly among your plants. You can consult a lighting specialist to determine the number of lights you’ll need.
- Adjust the Height of Your Grow Lights
: The height of your grow lights need to be adjusted as often as your plants grow. This is why most indoor gardeners invest in adjustable hanging ropes. These ropes allow you to conveniently adjust the height of your grow lights. Adjusting the height of your grow lights ensures maximum coverage and increases the amount of light your plants receive. When the plants begin to sprout, you may have to lower the light and then raise it as they grow.
- Monitor the Temperature in the Grow Room
: Most grow lights emit a high amount of heat, this is why it’s necessary to keep an eye on the temperature and humidity inside the grow room. LED grow lights produce the least amount of heat but still emit heat. Plants can’t survive when the temperature in the room is beyond normal; you should invest in a programmable thermostat to make this much easier. Also, get adequate cooling systems like inline fans to help cool the room when it overheats. You can also purchase a thermo-hygrometer which is a thermometer that has a hygrometer. This helps you monitor both the humidity and temperature level inside the grow room to ensure the best environment for your plants.
Cannabis Indoor Growing Tips
Here are some tips to ensure maximum yield when growing cannabis indoor
- Use the right genetic material. It is advisable to start growing with a seed rather than a clone because clones are weaker and they get infested by pests and diseases very easily.
- Before you decide to grow, ensure that you have enough space for a grow tent. Planning is a huge part of successful cannabis growing; make sure you get the right type of grow tent and grow accessories.
- Make sure to use the best soil to grow your weed. A very good natural soil provides your plants with all the nutrients and supplements needed for its growth.
- Go easy on the fertilizer. As much as plants need fertilizer for nutrients supply, don’t go overboard with it as this may weaken the plants.
- Choose the best lighting for your cannabis because this is the most vital aspect to grow cannabis successfully indoors.
