The ROI-E720 is a user friendly
commercial grade fixture. However,
Grower’s Choice does not recommend
the E720 for inexperienced growers
or tent applications. The E720 is
designed as a high output fixture for
commercial cultivation's, emitting
nearly the same PPF as a standard
1000w DE HPS fixture and lamp. With
intense PPF, 3k full phase spectrum
and balanced PPFD the ROI-E720 has the potential to produce the highest
yields and superior quality. GC highly recommends this fixture be used in
professional, environmentally controlled cultivation’s that supplement CO2.
Without using CO2 the grower may be introducing more light than the plants
can process, possibly causing stunted growth or light damage. Know your
garden and provide light accordingly.
