Malta Tip

Malta's Unique Growing Challenges

Malta's climate creates specific challenges for cannabis growers: summer temperatures frequently exceed 35°C, humidity fluctuates seasonally (69% in summer to 79% in winter), and alkaline water (pH 8.0-8.5) can cause nutrient lockout. These factors can produce symptoms that mimic other issues, so consider environmental factors first before changing your feeding regimen.

Prevention Tips for Malta's Climate

Heat Stress Management

  • Provide 30-40% shade cloth during peak summer (July-August)
  • Water during early morning or evening, never midday
  • Improve ventilation with oscillating fans
  • Consider heat-resistant strains (African/Middle Eastern genetics)

Water & Nutrient Management

  • Always pH adjust Malta's alkaline water (target 6.0-6.5 for soil)
  • Consider using reverse osmosis filtration for serious grows
  • Use 20-30% more Cal-Mag than standard recommendations
  • Flush growing medium monthly to prevent salt buildup

Pest & Disease Prevention

  • Use preventative neem oil spray during early vegetative stage
  • Install fine-mesh screens on windows/vents near outdoor grows
  • Monitor humidity closely during autumn/winter transitions
  • Use companion plants like basil, rosemary or mint
