Mas o Menos.... It will really not make that much of a differece in your yield... especially if your lights are at the correct distance from your plants...

Garden Knowm Reviewed by Garden Knowm on . Is gift wrap like mylar? A friend told me that the silver gift wrap is the same material as mylar. Anyone hear this? Does the silver gift wrap have the same reflective properties as mylar? Thank you for your time. :jointsmile: Rating: 5
