Hydroponics farming in India is booming, but choosing the right system can make or break your investment. NFT, Dutch Bucket, and A-Frame are the three most commercially viable systems — each with distinct advantages, cost structures, and ideal crop selections. This guide provides an honest, numbers-based comparison to help you choose.
System Overview
NFT (Nutrient Film Technique)
A thin film of nutrient solution flows continuously through shallow channels. Plant roots sit in the flowing nutrient stream. Best for leafy greens (lettuce, spinach, basil, herbs) with 25-30 day crop cycles. High plant density — 25-30 plants per sqm.
Dutch Bucket
Individual buckets filled with growing media (perlite, cocopeat) with drip irrigation. Ideal for vine crops — tomato, capsicum, cucumber, eggplant. Lower plant density (3-4 plants/sqm) but much higher per-plant yield and revenue.
A-Frame
Vertical triangular structures that maximize space utilization — 3-5x more plants per ground sqm than flat systems. Best for strawberries, lettuce, and herbs. Lowest setup cost but limited to small-rooted crops.
Cost Comparison (Per Acre, Inside Polyhouse)

Revenue & ROI Comparison
| Parameter | NFT (Lettuce) | Dutch Bucket (Tomato) | A-Frame (Strawberry) |
|---|---|---|---|
| Annual Yield/Acre | 40-60 T | 80-120 T | 15-25 T |
| Avg Price/kg | ₹80-150 | ₹40-80 | ₹200-400 |
| Annual Revenue | ₹32-90L | ₹32-96L | ₹30-100L |
| Operating Cost | ₹12-18L | ₹10-15L | ₹8-12L |
| Break-Even | 2-3 years | 2-3 years | 2-4 years |
Which System Should You Choose?
- Choose NFT if: You're near urban markets, want quick crop cycles, and focus on leafy greens/herbs
- Choose Dutch Bucket if: You want high-value vine crops with strong local demand for tomatoes/capsicum
- Choose A-Frame if: You want maximum space utilization, grow strawberries/herbs, and have limited polyhouse area
- Best hybrid approach: 60% Dutch Bucket (main revenue) + 40% NFT (quick-turn crop diversification)
