Alright plant lovers, listen up! If you're serious about indoor growing, these Spider Farmer supplemental light bars are a game-changer. Here's the deal - a lot of main grow lights might have a few UV or IR diodes, but honestly, it's often not enough to really make a difference. These bars are dedicated to giving your plants the specific light spectra they need. The UV bars (365-370nm) can help boost resin production and plant health, while the IR bars (730-745nm) are amazing for triggering flowering and making those buds develop properly. The set has four 23.6-inch bars total - two UV with 60 diodes each and two IR with 44 diodes each. They're super dense compared to other supplemental lights out there. They work perfect in 2x2, 3x3, or 4x4 tents alongside your main lights. You can control them with an app and they're compatible with GGS power kits. Built with a sturdy aluminum and copper frame, these things are meant to last up to 50,000 hours. Your plants will thank you come harvest time!
