HID lighting
High Intensity Discharge lamps are a tried and true method of growing and have been around for decades upon decades. These systems use high discharge bulbs with full spectrum light and can be interchanged for specific spectrums for specific grow periods (Veg Vs. Bloom – Metal Halide Vs. High Pressure Sodium). Though the power draw and heat are higher with a lower efficacy, these systems pump out massive fruits and flowers. There is a reason why they’re still in use today.
