-------------------
The Bluelab Conductivity Pen simply tells you that your s
have the right a of ent in your solution and lets you
know if adjustments are needed. To feed s well, we need to
know what we're feeding them. Start with a quality ent.
Measuring the conductivity every day is the best way to avoid
over-diluting or over-concentrating your ent solution.
Completely change the reservoir solution every 7 days. Top up the
ent level between changes - so your s always have the
right a of food. The Bluelab Conductivity Pen also measures
the temperature of the solution, as root is vital to the
success of a crop. Temperature affects the growth rate and
structure of a so a solution temperature of 18 - 22?C or 65
- 72?F is recommended. To make sure the s can get at the
food, you need to measure the pH of the solution. Check out our
handy Bluelab pH Pen so you have every tool required to manage
your ent solution. Features Measures conductivity and
