  • OPTIMIZED NIGHTSHADE FORMULA (4-18-38): Designed for tomatoes, peppers, eggplants, and potatoes—high potassium (38%) boosts fruit size, flavor, and shelf life while low nitrogen (4%) limits excess foliage.
  • COMPLETE MICRONUTRIENT SUPPORT: Includes Iron, Manganese, Zinc, Copper (EDTA-chelated), plus Boron and Molybdenum for better nutrient uptake across pH 4–9 and reduced lockout.
  • 100% WATER SOLUBLE & CLOG-FREE: Fully dissolves in water for smooth use in hydroponics, drip systems, foliar sprays, NFT, DWC, and Dutch buckets without clogging.
  • TESTED FOR PURITY & SAFETY: Independently tested for heavy metals and CDFA registered, ensuring reliable, safe, and high-quality performance.
  • ALL-IN-ONE FOR NIGHTSHADE CROPS: Suitable for all varieties—tomatoes, peppers, eggplants, potatoes, tomatillos, and more; trusted formula made in the USA since 1989.
  • FLEXIBLE APPLICATION RATES: Soil & containers: 1–2 tsp per gallon every 1–2 weeks. Hydroponics: 0.5–0.75 lbs per 100 gallons. Compatible with all irrigation methods including drip and foliar spray.
  • HIGH PHOSPHORUS FOR STRONG ROOT & BLOOM SET: 18% phosphorus supports vigorous root development and abundant flower set—critical for high-yield harvests from tomatoes, eggplants, and peppers.
