It is this characteristic which governs when these plants may be sown and harvested if growing outdoors. Hydroponic pH and EC levels can be measured with a dual meter. Basic wick. Revisiting this post coz I wanna find out what other brands are also okay～ From this article，I get the general idea the usage of nutrients， the convenience and budget tradeoffs. Stage 1 nutrient solution should have an EC of about 2.0 dS m-1, due to the lower overall nutrient concentration, and Stage 3 will have an EC closer to 2.4 dS m-1.
