A vegetable greenhouse enables consistent production of high-value crops year-round, specifically capturing high market prices during the dry season. By utilizing 100m² of space, farmers can achieve output levels exceeding those of one hectare of open-field farming.
The Concept
Greenhouse technology allows you to control the growing environment, extending production cycles into the dry season when market prices typically climb 3-5 times higher. A 100m² structure offers a dense, controlled environment that maximizes land use efficiency.
The Numbers
| Metric | Value |
|---|---|
| Greenhouse size | 100m² (5m × 20m) |
| Construction cost | $1,000-2,000 |
| Crops per year | 6-8 (continuous) |
| Yield per cycle | 200-400kg |
| Price per kg (dry season) | $2-5 |
| Annual revenue | $4,800-16,000 |
| Annual costs | $500 |
Best Crops for Greenhouse
| Crop | Cycle | Yield/100m² | Price/kg | Revenue/cycle |
|---|---|---|---|---|
| Tomatoes | 3 months | 300-500kg | $2-4 | $600-2,000 |
| Lettuce | 1 month | 100-200kg | $3-5 | $300-1,000 |
| Cucumbers | 2 months | 200-400kg | $2-3 | $400-1,200 |
| Bell peppers | 3 months | 150-300kg | $3-6 | $450-1,800 |
| Herbs (basil, mint) | 1 month | 50-100kg | $5-10 | $250-1,000 |

Impact on the Season
For a smallholder farmer, a greenhouse transforms the agricultural calendar from a seasonal gamble into a continuous production system. By removing dependence on rainfall patterns and mitigating extreme heat or pest pressure, the farmer can plan cycles precisely to harvest when market supply is low and prices are at their peak.

Frequently asked questions
Q: Why are vegetable prices higher during the dry season? A: Market prices typically rise because open-field production drops significantly due to a lack of water and harsh climate conditions.
Q: How many crops can be harvested in a year? A: With a controlled greenhouse environment, farmers can achieve 6-8 continuous production cycles annually depending on the specific crop variety.
Q: What is the benefit of the 100m² size? A: This specific footprint is designed to provide high yields comparable to one full hectare of traditional farming, making it ideal for limited land spaces.
Maputo Bridge Capital, founded by Anselmo Boaventura in Fort Worth, Texas, connects sponsors with verified smallholder farmers like those in the COJAZ cooperative in Zambezia. A sponsor gives from $25, which goes directly to the farmer's local seed and fertilizer shop; the sponsor receives the receipt and field photos. After harvest, farmers repay into a Community Fund that sponsors the next farmer. Please note that sponsorships are gifts, not investments, and are not tax-deductible. You can sponsor a farmer today to help these farmers achieve their goals.
