Detailed guide for choosing optimal drip tape. Examining thickness, emitter spacing, water flow and other characteristics.

What is drip tape?
Drip tape is flat polyethylene hose with built-in drippers (emitters) providing precise plant watering directly to roots. Proper tape selection saves up to 70% water and increases yield 30-50% compared to regular watering.
Interesting fact: Drip tape invented in Israel in 1960s and now used in 90+ countries worldwide for irrigating over 10 million hectares of agricultural land.
Main selection criteria
1
Tape wall thickness
Thickness measured in mils or millimeters. This is most important parameter determining tape service life:
6 mil (0.15 mm) - Economy class
- Service life: 1-2 seasons
- For light sandy soils without stones
- Cost: lowest (from 200 UAH/100m)
- Suitable for: annual crops, test plots
8 mil (0.20 mm) - Recommended
- Service life: 3-4 seasons
- Universal option for most soil types
- Cost: medium (from 350 UAH/100m)
- Suitable for: all vegetable crops, strawberries, flowers
10-12 mil (0.25-0.30 mm) - Premium
- Service life: 5-7 seasons
- For heavy clay and rocky soils
- Cost: highest (from 600 UAH/100m)
- Suitable for: perennial crops, professional use
Expert tip: For private garden optimal choice is 8 mil tape - lasts 3-4 years and has best price/quality ratio. Economy 6 mil option needs annual replacement, which proves more expensive.
2
Emitter spacing (distance between drippers)
Distance between drippers determines moisture uniformity. Choose spacing according to crop type and plant distance:
| Emitter spacing | Crops | Features |
|---|---|---|
| 10 см | Carrots, onions, radishes, lettuce, greens | Dense planting, continuous row moistening |
| 15 см | Beets, cabbage, garlic, strawberries | Medium density, water savings |
| 20 см | Tomatoes, cucumbers, peppers, eggplants | Most popular option, universal |
| 30 см | Zucchini, pumpkins, watermelons, melons | Large distance between plants |
| 40-50 см | Potatoes, corn, sunflowers | Sparse planting, point watering |
Life hack: If growing different crops - buy tape with 20 cm spacing. This is most universal option suitable for 80% garden plants.
3
Water flow (l/hr per 1 emitter)
Water flow affects irrigation speed and system operating time. Choose flow according to soil type:
1.0-1.3 l/hr - Slow flow
For heavy clay soils with low water permeability
- Irrigation time: 45-60 minutes
- Water fully absorbed without puddles
- Minimum evaporation and runoff
1.6-2.0 l/hr - Standard flow
Universal option for sandy loam and loam soils
- Irrigation time: 30-40 minutes
- Optimal speed and quality ratio
- Suitable for 90% private farms
2.7-3.8 l/hr - Fast flow
For light sandy soils with high water permeability
- Irrigation time: 15-25 minutes
- Quick soil water saturation
- Time savings but greater overwatering risk
Important: High flow (3+ l/hr) on clay soil leads to puddles and water runoff. Low flow (1 l/hr) on sandy soil - very long irrigation (60+ minutes).
4
Row length and pressure compensation
The longer rows in your garden, the more water pressure drops at tape end. This leads to uneven watering:
Up to 50 meters:
Regular tape without compensation suitable. Flow difference between row start and end - up to 10%.
50-100 meters:
Pressure compensating tape recommended. Ensures uniform flow along entire length. Cost 30-50% higher.
Over 100 meters:
Better use drip hose instead of tape, or divide system into several zones with separate connection each.
Tip: If your garden has rows over 50 meters - connect tape from both sides (row start and end). This ensures uniform pressure without overpaying for compensated tape.
5
Required quantity calculation
To properly calculate tape quantity for your garden:
- Measure each row length where planning drip irrigation
- Count number of rows
- Multiply length by number: length × rows = total length
- Add 10-15% reserve for trimming and connections
- Round to whole roll (100, 200, 500 or 1000 m)
Calculation example:
Garden 20 meters × 10 meters
Bed width: 0.9 m, number of beds: 10 pcs
Calculation:
20 м (довжина ряду) × 10 (рядів) = 200 м
200 м + 10% запас = 220 м
Need: 1 roll 200 m + 1 roll 50 m (or 300 m)
Savings: Large rolls (500-1000 m) cost 15-20% cheaper per meter. If need much tape - buy one large roll instead of several small ones.

Additional expert tips
- For greenhouses use tape with maximum spacing (30-40 cm) - less evaporation and soil retains moisture better
- Cover tape with mulch (straw, black film) - extends service life and reduces mechanical damage risk
- Always use filter at least 150 mesh at system inlet - drip tape emitters very sensitive to contamination
- Buy tape from one manufacturer for entire garden - easier to select accessories and connectors
- Store tape indoors in winter, rolled up - frost and UV rays shorten service life
