Mylar: one of the most reflective grow tent wall cover
There is nothing I like more than sitting on the lawn near the pool, my feet in the water while taking a long sunbath. Plants usually feel the same way and will thrive if provided with enough water and light, as you can see it happening in the nature surrounding you.
Indoors (choosing the right growing tent Plantsily.com/grow-tent) , things happen a bit differently.
Your lamp produces a light good enough for the plants to grow but it must be reflected to pass through the bushy canopy, reach lower branches and improve the overall amount of light received by each plant.
It’s a very cheap and efficient way to maximize your crop’s potential while stabilizing your power bills, proved over the years and used by any decent grower.
When looking for the best reflective material for grow tent, various option can be considered:
- flat white paint is inexpensive and easy to clean, light reflectivity around 80%
- styrofoam very cheap and durable, 60-70% light reflectivity
- aluminium foil bad idea, creases easily, around 50 % light reflectivity
- but one word really comes to mind: Mylar.
What is mylar?

Mylar for sale is cheap and has a 90-95% reflectivity, making it the perfect grow room reflective material.
It usually comes in three different ways, plain sheets, metalized mylar sheets and emergency blankets, which are a bit less efficient.
