Cultivate sub-reflector

A reflector that used for what ?

In order to get the most out of the light emitted by the bulb, it is necessary to use a reflector. Its role is to focus the light diffused by the light bulb in the direction of your plants.
The reflector will also help to distribute the light throughout your culture.

How to choose your reflector ?

There are different types of reflectors to choose from depending on your grow space, your budget, thelight bulb used and your needs.
It is possible to separate them into two distinct families : the reflectors open and the reflectors closed.

It is advisable to invest in a reflector of quality if you want to get nice crops and good yield. But when you're a beginner in the indoor growing it is not always easy to know what to choose in front of so much choice.
We are going to try to explain to you the differences to help you in your choice.

First, in order to disseminate more effectively and evenly light, it is advisable to choose a reflector with a coating of beaten, if you use a light bulb to HPS or MH, in effect a smooth surfaces will create hot spots. Conversely if you use bulbs type CFL, a coating smooth can suit knowing that the CFL only emits very little heat.
It is also mandatory that your grow space is covered with a coating reflective type Mylar or Orca so that the reflection light is optimal, and the loss of luminous flux to a minimum.

The reflector open :

This type of reflector is generally much more affordable than a reflector closed. In general the reflectors that are open are light, practical and easy to install, and it is for this reason that a lot of beginners in the indoor growing choose this less costly alternative.
However, they are open on the sides and let escape the light that cannot be absorbed by your plants. Conversely, the fact that the reflector is open allows your plants to absorb directly the light emitted by the bulb.

Advantage of a reflector open :
Generally affordable
No loss of lumens
Simple to install
Possibility to change the light bulb more easily
Lightweight and practical

The reflector is closed :

If you have problems to regulate the temperature of your culture room because of too much heat emitted by your lamp, the reflector closed is probably the solution that you need.
In fact, the reflectors closed are hermetically sealed by a window that allows to reduce the emission of heat of the lamp within your space of culture.
This type of reflector imposes a loss of light due to the glass, but this loss is offset by the fact that a reflector is closed can be closer to your plants without risk of burning them.
Also, they are usually equipped with openings on the sides in order to place a sheath and to extract the heat emitted by the lamp.

Advantages of a reflector closed :
Diffuses and emits less heat in your room culture
Can be closer to your plants without risk of burning them
Uniform distribution of the light
Security Aspect through the glass
Easy cleaning (it is necessary to clean the glass once per month)

Understanding the distribution of the light :

There are a lot of reflectors, each of which has a shape specific.
The shape and the coating used will determine the distribution of the light.
The diagrams below will help you understand the distribution of light, here in the lumens, according to the different type of reflectors :

Stuff to know :

  • The more the reflector is located near the bulb, the more effective it will be.
  • Over the space of culture, the larger the reflector must be large.
  • There are reflectors are adjustable to adapt to different sizes of crops.
  • Beyond 2m2, a space of culture requires two bulbs. There is a reflector for a lamp, but also for two lamps in order to have a larger contribution of light in a large space.
  • In a large space, the use of a reflector on a movable rail is recommended in order to standardize the diffusion of the light on the whole of your culture, and to thus avoid hot spots.
  • Be sure to verify that the reflector chosen is compatible with the bulb used : all of the bulbs may not go on all the reflectors
