The ROI-E720

The ROI-E720 is a user-friendly commercial grade device. However, Grower's Choice does not recommend the E720 for novice cultivators or tent applications. The E720 is developed as a high output device for commercial cultivation, producing nearly the same PPF as a conventional 1000w DE HPS fixture and lamp.

With extreme PPF, 3k full phase spectrum and balanced PPFD the ROI-E720 has the potential to produce the highest yields and superior quality.

GC strongly advises this device be utilized in professional, environmentally controlled cultivation that supplement CO2. Without utilizing CO2 the grower might be presenting more light than the plants can handle, possibly causing stunted growth or light damage. Know your garden and supply light accordingly.
