      FAQs

      Will a metal halide globe run on an HPS ballast?

      No, standard MH globes need an MH or switchable ballast — but retro MH lamps like the Cultiv8 600W are purpose-built to run on an HPS ballast.

      How often should I replace grow light globes?

      HID globes lose output well before they fail. Most growers replace HPS and MH lamps after around 12 months of regular use to keep yields consistent.

      Do CMH globes fit standard E40 fittings?

      No, CMH lamps use a PGZ18 base — but a PGZ18-to-E40 adaptor lets you run CMH in a standard E40 fixture.

      Welcome to The Grow Guys

      We built The Grow Guys from the soil up — well, coco and perlite. Before we sold gear, we bought it, ran it, and learned the hard way what's worth the money and what ends up in the shed. That's the filter everything on our shelves passes through. No sales scripts, no rebadged junk, no telling you what you want to hear. Just gear we'd run ourselves and advice from people who actually grow. Chasing higher yields, tighter flowers, or your first harvest? You're in the right place.
