Vevor’s 36‑site, 4‑layer pipe system arranges four dark grey PVC grow tubes to save floor space while reducing light penetration and algae. The kit uses a recirculating, timer‑driven irrigation setup: a supplied 4 W pump lifts solution to the upper pipe and gravity returns it through the channels, with a 24‑hour plug‑in timer to schedule cycles. Package contents include planting tubes, hoses, inlet/outlet heads, 36 baskets, 36 sponges, tweezers, a rubber mallet, aluminum tape, and instructions. Recommended pairing is an external 20 L water reservoir (not included). Dimensions are 870 × 560 × 990 mm, and the model identifier is VVGrey4‑36. This pipe‑channel recirculation is well suited to leafy greens and herbs needing consistent nutrient flow and aeration.
