The ROI-E420 was specifically developed with the enthusiast "in tent" applications and cultivators who need a compact led fixture that generates high photon output. The e420 is great for tent grows as its compact design alleviates growth space while still supplying high energy output to the canopy producing remarkable yields during bloom.
The E420 is also excellent when utilized as an efficient veg device in large scale and commercial cultivation as the 3k full phase spectrum provides all the PAR required for all stages of plant life. It is not necessary to run CO2 with the ROI-E420.
Nevertheless, supplemental CO2 between 450-800 ppm will be beneficial and also boost yield potential.
