Question 1

Can I buy a grow light that covers a grow area less than 4x2?

Accepted Answer

Ideally you should buy grow lights that provide an exact amount of coverage. This is because getting a light with a smaller coverage would result in the plants that are further away from the center getting lesser coverage. However, you can use two 2x1 grow lights to get a proper scatter over the area. However, using a single grow light with a proper 4x2 coverage would be best suited for your plants.

Question 2

Can I buy a grow light that covers a grow area of more than 4x2?

Accepted Answer

Getting a grow light that is somewhat larger than the actual coverage shouldn’t hurt. For instance you can get a 4x3 or a 4x4 grow light. However, getting a grow light that covers 5x5 or larger would actually be counterproductive as that would be too much light for your plants. When you provide more light to your plants than is needed, you are stressing them out and they will have to produce enzymes beyond their capacity and need. This leads to plants getting stressed and in an unusual growth. Similarly, if your light is too intense, there might be a ‘light burn’ that can occur. Hence, it is recommended only to get a light that is 4x2 to 4x4.

Question 3

What kind of lights are the best suited for these grow tents?

Accepted Answer

LED grow lights are generally best suited when growing cannabis plants indoors, and particularly in grow tents. This is because most of the modern-day LED grow lights operate at low temperatures and do not heat up. They do not cause heat burns or light burns to plants if used correctly, while also consuming very little electricity when compared to HID lights or other older forms of lighting. These lights also provide full-spectrum lighting which means your plants are covered for both, the vegetative as well as the flowering phase and you don’t have to change lights every time the phase changes.

Question 4

How to make sure that my grow lights last a long time?

Accepted Answer

To ensure that your grow lights last you a long time, make sure you’re switching them off from time to time, and also ensure that you are keeping them away from the three things that can cause them to go bad - heat, water and dust. Generally in a grow room, there is no dust and heat is often controlled and reduced to suit the plants. However, considering that there’s often a lot of water involved when it comes to feeding your plants and helping them grow, make sure that you stay careful and do not accidentally spill some on the lights.

Question 5

How to ensure that grow lights don’t damage the plants?

Accepted Answer

To make sure that your plants aren’t getting the much-dreaded ‘light burn’, make sure you are keeping your lights at a safe distance from them. This is generally observed in the top regions of the plants. Similarly, if you begin to see any signs of stress on the plants, such as unusual buds growing, make sure that you move your light a little further up to reduce the impact. Also make sure you reduce lighting hours as the plant grows. A flowering plant might do well with just 10 hours of light but a plantling at its young stages might need up to 22 hours of light.

Question 6

Where to buy the best LED lights for 4x2 grow tents?

Accepted Answer

As mentioned earlier, Amazon is perhaps the best place to get hold of these grow lights, because it helps you get better discounts and easy returns, as well as doorstep delivery. However, you can always walk into your neighbouring gardening store and get them. Grow lights are pretty common and can be found in almost any place that sells gardening equipment. However, Amazon gives you the option to go through a much larger number of options to choose from, which may not be available in the local stores nearby.
