Who This Is For
- You are switching to 1680D fabric because flimsy zippers on cheaper tents keep failing and ruining your environment.
- You are adding the extension kit because your plants keep outgrowing the ceiling height and suffering from light burn.
- You are upgrading to the Goliath because your previous tent fabric was too thin and leaked light during dark cycles.
What We Found
- The 1680D fabric feels heavy in your hand and lacks the pinhole leaks we see on cheaper 600D models.
- The rear access door makes it much easier to reach plants in the back corner without moving everything around.
- We noticed the 12 inch height extension is a game changer for growers running large LED panels.
What Users Say
- Buyers who upgraded from flimsy brands say they stopped worrying about the frame buckling under heavy filters.
- Users who use the height extension report having much more room for overhead gear and taller plants.
