Uses for Trubone+

TruBone+ is suitable for hydroponic and soil-based plants that have a high demand for phosphorus with a touch of nitrogen as they grow. In particular, this liquid fertilizer guides growth through the vegetative state and into bloom. Use this Safer® Brand plant food on house plants, flowers, vegetables, fruits, shrubs or trees.

What's in Trubone+?

TruBone+ features fermented corn and steamed bone meal as its primary ingredients. This combination is loaded with phosphorus, nitrogen and valuable amino acids and gives TruBone+ an N-P-K ratio of 6-20-0. These key nutrients will strengthen developing plants, add proteins and build a healthy cellular structure of leaves and flowers.

Tips for Use

Use TruBone+ in conjunction with base-level fertilizers. For the best results when using this Safer® Brand plant food, follow these procedures:

  • Base your use of TruBone+ and any other fertilizer on the feeding schedules provided on their labels.
  • Intense dosages can trigger a stress response from your plants. If signs are evident, pull back on your dosage.
  • Most plants thrive in pH levels between 5.5 and 6.5. Even after you have attained this pH, adjustments may be needed because water quality can alter pH levels. Your system's pH levels are also affected by seasonal changes.
  • If you're running a hydroponic system, drain and replace the nutrient solution on a weekly basis. If you don't, you could quickly see a nutrient imbalance.
  • Monitor water quality and nutrient strength frequently with a conductivity or PPM meter. Work to resolve these issues if any imbalances are uncovered.

Trubone+ for Hydroponics

Hydroponic operations will benefit from the nutrients provided by TruBone+ concentrate from Safer® Brand. Mix 6 ml to 15 ml of this plant food with every gallon of water in your reservoir. In the vegetative stage, use between 6 ml to 8 ml. As the plant begins to bloom, provide a slight boost with a range between 6 ml and 9 ml. Raise the dosage to 13 ml to 15 ml as the plant blooms and ripens.

The nutrient mix in the reservoir should be replaced every 3 days in early flowering. In mid- to late-flower it should be changed every other day.

Trubone+ for Garden Plants

Soil-based dosage guidelines are the nearly same as those in the hydroponic section above. The only change is that you should mix TruBone+ into your watering system, where it can be delivered during daily watering regimens.
