        FAQs

        How do I choose the right grow tent size for my plants?

        It depends on your plant count, lighting setup, and available space. A 2’x4’ tent suits 2–4 plants, while 4’x8’ and 10’x10’ options can handle full cycles for commercial or caregiver grows. Also consider height for light clearance and vertical growth.

        What features should I look for in a high-quality grow tent?

        Prioritize thick canvas material (1680D+), heavy-duty zippers, double cinching duct ports, and a strong steel frame. Also look for diamond reflective mylar, large access windows, tool pouches, and height extension kits for taller plants or lights.
