In a HydraMax RDWC system, nutrient dosing is the heart of plant performance. Partnered with @Nuravine 's automated dosing technology, growers can fine-tune feeding schedules with lab-grade precision — no more guesswork.

From seedling to bloom, batch dosing ensures consistent EC levels, maximizes plant uptake, and reduces waste.

Smart dosing = stronger plants, faster grows, less waste.

In RDWC, your pH will naturally shift as plants feed — that's pH drift. A little is normal, but too much can lead to nutrient lockout and weak growth.

💧 Keep your range tight (5.5–6.5)
📊 Monitor daily
⚖️ Use buffered nutrients
