How many lights do I need?

We have touched on grow lighting several times before on our blog. It’s a really important factor in your grow room or tent, so imporant that we’re writing about it again!

So how many grow lights do I need?

Knowing the correct amount of light that is needed for your indoor grow room isn’t an easy thing to work out, especially if you are new grower looking to produce your own fruit and veg. It can take a long time for a new grower to find a great grow room setup and it usually comes after you have learned by doing.

Before you set up the indoor grow room, there is some advice on the lighting that could save you time and troubles below.

Before any grower – no matter how experienced they are – sets up a grow room, they first must know how many lights are needed. The amount of lights you use depends on the size of your grow room, the amount of plants you are growing and the power of the lights you purchase.

The higher the wattage on your lighting system will usually result in a higher yield. For example, a 400w system usually grows 4 or 5 plants in medium, 2 gallon, sized containers where as a 1000w setup could hold almost double the plants in larger 4 or 5 gallon containers.

More powerful lights have hidden costs!

It is important to know that the higher price of a high watt system isn’t the only cost. More powerful lights means more heat generated and having a hot grow room could badly affect your crops. If your grow room budget allows you to purchase a high powered lighting system, be ready for the extra cost that comes with cooling your grow room down.

If you cannot afford 1000w lighting, don’t worry because a 400 or 600 watt lighting system still provides efficient lighting with reduced heat. However if you do have the money to purchase both powerful lights and a method to reduce the heat, it is more likely you will have a larger and better yield.

What temperature should my grow room be at?

The best temperature for a grow room is around 21 – 23 degrees, if you purchase powerful lights without a cooling system in place and the temperature gets too high, the quality of the fruit and vegetables produced in the environment will be lacking.

Always keep the lights within your grow room a couple of feet away from the plants otherwise they could be seriously damaged. A good way to determine if your lights are too close to your plants is to place your hand on the tops of the crop and if you feel the heat, the lights are too close.

With these basic tips and tricks for lighting within your grow room, it should be a little simpler when it comes to setting up. If you are new to the growing hobby, this knowledge on lighting should save you some troubles and help you with your yields.
