Why pH, EC & Temperature Matter
Electrical conductivity (EC) indicates the total amount of nutrients in your solution. pH determines how acidic or alkaline your medium is — which controls whether plants can actually absorb those nutrients. Temperature affects growth rate and plant structure. Get all three right from the start and you’ll avoid nutrient lockout, burn, and stunted growth — giving your plants everything they need to thrive.
