Reviewing the Mars Hydro 300 Watt LED Grow Light

In this video I give my review of the Mars Hydro 300 Watt LED Grow Light.  I have been using these grow lights with all three of my greenhouses during this current grow.  Here I show my large greenhouse which has four Blue Dream plants growing under two Mars Hydro 300W LEDs.

I like to have a maximum of two plants below one of these LEDS.  These plants are currently starting their 5th week of flower and are really looking amazing!  The lights are only $80 a piece at the Amazon link below.

As a reminder, I am using these grow lights for supplemental lighting and not as the main source of light for my cannabis plants.  Since I am growing outdoors in a greenhouse, I use the sun as the main source of light and only use these LEDs as additional lighting when there aren't enough hours of light in the day.

Happy Growing!
