  • Watch for signs of stress from your plants and pull back on TruBone+ dosage as needed.
  • Adjust your nutrient solution to maintain a pH from 5.5 and 6.5. Also be aware that water quality and even the season can affect pH levels.
  • Use a conductivity or PPM meter to monitor nutrient strength and water quality on a regular basis. If any imbalances are detected, take steps to resolve.

Trubone+ for Hydroponics

Safer® Brand TruBone+ is designed for use with hydroponic operations. Depending on your plant stage, mix 6 ml to 15 ml of TruBone+ with every gallon of water in your reservoir. Use 6 ml to 8 ml for vegetative stages. The transitional period to blooming stage gets a slight boost, from 6 ml to 9 ml. To help with full blooms and ripening, increase the dosage to 13 ml to 15 ml per gallon.

Replace your reservoir’s nutrient mix every 3 days in early flower and then every other day through mid- to late-flower.

For soil-based plants, follow the same dosage guidelines as mentioned in the hydroponic section above, except that you will mix into your watering system and feed on a daily basis.
