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 created as a high output device for commercial cultivation, producing almost the same PPF as a conventional 1000w DE HPS device and lamp. With intense PPF, 3k full phase spectrum and balanced PPFD the ROI-E720 has the potential to generate the highest yields and superior quality.
GC strongly recommends this fixture be utilized in professional, environmentally controlled cultivation that supplement CO2. Without utilizing CO2 the cultivator might be introducing more light than the plants can process, possibly causing stunted growth or light damage. Know your garden and supply light appropriately.
