N-Primer
TPS N-Primer by True Plant Science is a slow-release nitrogen supplement formulated with a balanced source of both positively charged (ammonium) and negatively charged (nitrate) nitrogen. This dual-charge formula stays close to root hairs and resists runoff, creating a reliable, consistent nitrogen supply that steadily releases to sustain vigorous vegetative growth and promote dark green leaves.
The slow-release behavior makes N-Primer particularly useful in high-frequency watering programs (coco, hydro) where rapid runoff can deplete nitrogen faster than standard nutrient solutions replenish it. By resisting runoff and staying near root hairs, N-Primer ensures nitrogen is available where plants need it most.
Special plant extracts in the formula help plants take up nitrogen faster through improved uptake efficiency. Use during vegetative growth and early flowering. Compatible with the complete TPS system alongside Base A+B, CalMag OAC/Complete, and Root Boost. Apply in root-zone irrigation per TPS's feeding schedule.
