Vevor’s Hydroponics Growing System (36 sites, 4 layers) is a compact PVC‑pipe kit designed for nutrient‑film style growing. The dark grey PVC reduces light penetration to limit algae. It ships with a 4 W submersible pump rated at 200 L/h and a 24‑hour plug‑in timer to automate circulation with adjustable on/off cycles. The kit includes planting tubes, hose, inlet and outlet heads, 36 baskets and sponges, tweezers, a rubber mallet, aluminum tape, and instructions. Vevor recommends pairing the rack with a 20 L water reservoir (not included). Assembled size is about 870 × 560 × 990 mm, with 2.5 in tube diameter and 2 in site spacing.
