ROI-E420 LED Grow Light
The ROI-E420 was specifically design with the hobbyist “in tent” applications and cultivators who need a compact led fixture that produces high photon output. The e420 is great for tent grows as it’s compact design relieves grow space while still providing high energy output to the canopy producing impressive yields during bloom. The E420 is also great when used as a efficient veg fixture in large scale and commercial cultivation's as the 3k full phase spectrum provides all the PAR needed for all stages of plant life. It is not necessary to run CO2 with the ROI-E420. However, supplemental CO2 between 450-800 ppm will be beneficial and increase yield potential.
