    Q & A:

    Q: What is the benefit of the Touchscreen Controller

    A: Automated Sunrise & Sunset feature built into the master controller helps you recreate mother nature to tap into the full potential of your crop. 
    Ex: You can set at 7:00 AM for your Optic 4XL to come on with just the Bloom Enhancers to click on then have the COBs click on 30 minutes later and gradually increase intensity over time and your plants will love you for it.
