The ROI-E420

The ROI-E420 was especially manufactured with the enthusiast "in tent" applications and cultivators that need a compact led device that generates high photon output. The e420 is great for tent grows as it's compact design alleviates growth space while still providing high energy output to the canopy producing remarkable yields during bloom.

The E420 is also excellent when utilized as an efficient veg fixture in large scale and commercial cultivation as the 3k full phase spectrum supplies all the PAR needed for all stages of plant life. It is not necessary to run CO2 with the ROI-E420. However, additional CO2 between 450-800 ppm will be beneficial and also increase yield capacity.
