The ROI-E720 is a user-friendly commercial grade device. However, Grower's Choice does not recommend the E720 for novice growers or tent applications. The E720 is designed as a high output fixture for commercial cultivation, producing almost the same PPF as a standard 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 advises this device be utilized in professional, environmentally controlled cultivation that supplement CO2. Without using CO2 the cultivator may be presenting more light than the plants can handle, possibly causing stunted growth or light damage. Know your garden and supply light appropriately.
