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.
