Macrotunnel for Bell Pepper Growing
A macrotunnel for bell pepper works especially well in climates where the main challenge is rainfall rather than cold nights. Overhead protection drastically reduces anthracnose and foliar spotting from rain splash, without the full investment of a closed greenhouse. It is the ideal entry point into protected cultivation for growers scaling up gradually.

Anthracnose pressure reduced
Overhead cover eliminates rain splash that activates Colletotrichum spp., the primary cause of fruit rot in pepper in rainy regions.
Scalable entry investment
Allows growers to start protected cultivation with less capital and scale to a closed greenhouse in future cycles once the production model is proven.
Earlier harvest
The warmer microclimate under plastic advances harvest by 10-15 days compared to open-field production in the same region.
Agronomist Tip
Use thermal or diffuse plastic with no more than 15% shade factor in pepper macrotunnels, peppers need high light intensity to develop proper fruit color and Brix.
