ମୁଖ୍ୟ ତଥ୍ୟ

• Vertical orientation multiplies growing capacity in the same floor footprint
• Nutrient solution is pumped to the top and gravity-fed downward past all root zones
• Common for lettuce, herbs, strawberries, and leafy greens
• Popular commercial and home systems include Tower Garden, Zipgrow, and DIY PVC towers
• Root zones remain moist but not submerged — similar to NFT mechanics
• Excellent for balcony and patio growing where floor space is limited
