TopoLite’s Indoor Kits 2-in-1 48x36x72 refers to a dual‑chamber, multi‑stage grow tent offered under the TopoLite brand at retail. The 48 × 36 × 72 inch footprint (about 122 × 91 × 183 cm) is a common 4×3×6 ft format that lets growers run propagation/vegetative work alongside a separate main chamber, enabling staggered or perpetual cycles within a single enclosure. Retailers list this SKU explicitly as a TopoLite 2‑in‑1 or “lodge” style tent, and some shops bundle it in complete kit configurations; contents can vary by seller.
