Hydroponics Growing System 90 Sites, 3-Layer PVC Kit - High Yield

In this review the VIVOSUN Hydroponics Growing System is assessed as a beginner-friendly 3-layer kit for growing leafy vegetables indoors or on a patio. The bottom line: it is best for growers who want to double yield in limited space using a nutrient film technique without soil. The package combines food-grade PVC-U pipes, a timed circulation pump and nest baskets so a novice can set up a continuous thin nutrient flow; that timed circulation is the single biggest reason to consider this kit for steady, efficient growth.

Key Features

• High yield soilless cultivation: Nutrient film technique helps plants reach production potential and can deliver higher yields than traditional soil methods in the same footprint.
• Timed circulation pump: The included timer defaults to 5 minutes on every 30 minutes, automating nutrient flow to save effort and extend pump life.
• Space efficient 3-layer design: Three stacked PVC-U pipes create 90 planting sites that maximize vertical growing area for leafy greens in limited spaces.
• Food-grade PVC-U pipes: Durable, easy-to-clean 31.1 in long, 2.8 in diameter pipes provide a sanitary channel suited to vegetables and seedlings.
• Complete starter kit: Comes with pump, timer, tubing, nest baskets, sponges, tweezers and instruction manuals so beginners can assemble and begin growing quickly.

Who It's For

The system is aimed at hobby growers, beginners to hydroponics and small households who want to grow lettuce, celery, beets and similar leafy vegetables indoors or outdoors without arable land. Its automated timer and simple assembly make it especially useful for people who need low-maintenance circulation and steady nutrient delivery.

Experienced commercial growers or those needing larger root crops and heavy fruiting plants should look elsewhere, because the kit is optimized for leafy varieties and limited to the pipe dimensions and 90 planting sites provided.

Pros & Cons

Pros

• Easy assembly with clear instructions makes it accessible to first-time hydroponic gardeners.
• Timed pump circulation conserves nutrient solution and reduces manual watering chores.
• High site count and vertical stacking double potential yield while saving space.
• Included accessories (baskets, sponges, tweezers) give a true plug-and-play experience.

Cons

• Some users report the pump may struggle to achieve strong flow for full circulation in all setups, so placement and tube routing need care.
• Mixed reports on leak resistance mean occasional sealing checks are advisable during assembly and early operation.
