Reflective sheeting for grow rooms is an absolute must if you want to get the most out of your plants in as far as yield and light exposure. Professional growers cover the inside of their grow rooms with this type of sheeting or they use a grow tent already equipped with it.

Today we’re going to have a look at the different types of reflective sheeting that we stock at GB The Green Brand so that you can make an informed decision regarding which one is best for you.

Reflective sheeting for grow rooms | History

When people first started growing cannabis, they didn’t pay much attention to the walls around them – after some time they logically deduced that if they created a more reflective surface they could improve the amount of light being spread around the room from the grow lamps.

The first thing they did was to start painting their walls white or using any type of reflective material they could find. This did indeed improve light reflection by around 5 to 15% at the most when it comes to painting the walls. Those that decided to use reflective material, however, experienced some pretty negative side effects, as their grow room was heating up much more than it should, with hot spots forming all around the room.

Reflective sheeting for grow rooms | How it’s used now

Nowadays, thankfully, there are various different types of reflective sheeting available, specifically designed to be used in indoor grows. This type of sheeting or plastic is generally known for the fact that it can reflect up to 80% of all light that hits it, which stops it from heating up like other materials.

The most typically used reflective sheeting in this industry is either white or silver aluminum; both are great for growing cannabis, although there are a few differences between the two.

Aluminum sheeting: this type of sheeting is the best at reflecting light generated by artificial lighting (+90%) although it isn’t the best at spreading it, so you may end up with hot pockets.

White sheeting: this particular type of sheeting isn’t as reflective as aluminum sheeting (-90%) although it is much more balanced. It spreads light much more efficiently, which stops hot spots from forming.

These two comparisons don’t really help much when it comes to making a choice, and most people basically just go with the silver sheeting because it’s shiny. In order to make this a bit easier we’re going to go through our top 5 favorite sheetings for indoors, all of which you can get on our online store.
