You may choose to install a nutrient level indicator. To do this, simply drill a hole through the bottom of a section of 1/2" clear rigid tubing as shown at left. This will allow you to secure the bottom of the tube to the inside of the planter with a plastic tie.

I highly recommend adding this feature as there is no other means of determining the level of nutrient inside the planter and you certainly don't want to risk drying out your crop!
