Uses for TruAmino+

The nitrogen in TruAmino+ is rapidly absorbed by plants and allows them to properly develop cellular structures related to fruiting and flowering. Make TruAmino+ part of your feeding schedule for flowers, vegetables, herbs, shrubs, trees, annuals, perennials, and indoor and outdoor potted plants.

What's in TruAmino+?

TruAmino+ contains lysine, a powerful amino acid. Lysine gives plants a high concentration of nitrogen to stimulate microbe population development. This granular fertilizer carries a 15-0-0 N-P-K ratio, so it serves as a supplemental plant food for use in conjunction with other fertilizers from Safer® Brand.

Tips for Use

Dilute TruAmino+ with water as directed on the label. Though these instructions provide information for a safe application, follow these procedures to get the most from TruAmino+:

  • Use TruAmino+ as a supplement to additional base-level fertilizers. Follow all feeding schedules as directed.
  • If stress is evident on your plants, they may be overwhelmed by excess nutrients. To keep your hydroponic system balanced, drain and replace your nutrient system once a week.
  • Conductivity or PPM meters should be used to monitor pH levels.
  • Plants commonly prefer pH levels between 5.5 and 6.5. Adjust and measure your nutrients to hit this pH level.
  • Worm castings are an excellent top-dress for your media. Castings enrich soil, repel some pests and add beneficial nutrients.

TruAmino+ for Hydroponics

Provide 1 ml to 5 ml of TruAmino+ per gallon of water for hydroponic operations. The exact dosage depends on your plant's stage of development. Plants need a 4 ml shot of TruAmino+ during their transition from vegetative growth stage and into bloom. During blooming and ripening stages, use 1 ml to 5 ml per gallon.

TruAmino+ for Garden Plants

Soil-based plantings require a TruAmino+ dosage of 1 ml to 5 ml for every gallon of water used in regular watering. Plants blooming or ripening use the standard range of 1 ml to 5 ml. Those transitioning to bloom require 4 ml of TruAmino+ with every gallon.
