🌡️ Indian Climate & Season Adjustments
- Summer (35–45°C): always go one size UP — moisture evaporates 30–40% faster
- Monsoon: focus on drainage holes — use perlite-heavy mix to prevent root rot
- Madanapalle / Delhi / Jaipur (hot-dry): use cocopeat at 50% for moisture retention
- Mumbai / Chennai (humid coast): standard sizes work — add 20% extra drainage material
- Terracotta pots lose 20–30% more water than HDPE grow bags — always size up
- 4th floor+ balconies: prefer HDPE grow bags (lightest) or Geo fabric bags

Understanding the 40:40:20 Soil Mix
Why each component matters in Indian heat — and when to adjust the ratio.
Cocopeat
Retains moisture without waterlogging. Made from coconut husk widely available at ₹50–80 per 5L brick on Ugaoo and local nurseries. Increase to 50–60% in Madanapalle, Delhi, Jaipur where soil dries fast.
Compost / Vermicompost
Provides nutrients and beneficial microbes. Vermicompost is best ₹150–250 per 5kg from brands like Nisarguna or Vegrow. Cow dung compost works as an affordable substitute from local nurseries.
Perlite / River Sand
Improves drainage and aeration. Perlite is lighter (ideal for balconies) at ₹200–350/kg available on Amazon India. River sand from local hardware stores at ₹20–50/kg is a cheaper alternative.
⚠️ When to Adjust the Ratio
- Microgreens & leafy herbs: skip perlite use 60% cocopeat + 40% vermicompost only
- Root vegetables (gajar, muli): use 30% cocopeat + 40% compost + 30% coarse river sand for loose structure
- Monsoon season: reduce cocopeat to 30%, increase perlite to 30% for better drainage
- Fruit trees (nimbu, amla): add 10% red garden soil for weight, minerals, and microbial diversity

This calculator is based on multi-month grow bag trials in Madanapalle, Andhra Pradesh one of South India’s hotter, semi-arid climates along with data from a collaborator network across Bangalore, Mumbai, and Chennai. Container sizes, soil volumes, and climate adjustments reflect real Indian conditions, not Western gardening books written for 18°C summers.
Soil prices are checked against current Indian market rates on Ugaoo, Amazon India, and local nurseries. Container size guidelines are cross-referenced with ICAR (Indian Council of Agricultural Research) recommendations for container vegetable cultivation. Updated regularly as new trial data is collected.
