ELEMENTAL OHM EARTHLIGHT Instructions

EARTHLIGHT™ INSTRUCTIONS
Please read and beome familliar with these instructions before installing your device.
Retain these instructions for reference. They also contain a coupon code.*
Congratulations on your Earthlight™ purchase! The Earthlight™ is a novel device for the
long-term monitoring of the moisture level of your indoor potted plant's soil. It is also a
soil quality indicator and only works in rich, living soils loaded with beneficial microbes.
You can install it as a long-term moisture meter for your indoor potted plants, a means
to monitor new potted plantings, a means to test the effectiveness of soil amendments, as
well as a portable soil quality detector.
The device utilizes no power source other than soil to generate a small amount of electric-
ity to light the green LED indicator light. Good living soils will produce a charge when the
plant is properly watered. If your soil needs to be amended, recommended amendments
are listed under "Amendments" after the installation and usage instructions.
The Earthlight™ is only intended for long-term installation in indoor plants in contain-
ers, but can be used briefly in open soil or outdoors for field testing or to monitor amend-
ments while you add them to an area. Please do not use in very acidic soil (PH 5.5 or
lower) long-term or in evergreen plants such as junipers, pines or spruce. It may rapidly
degrade the metal rod. Visit eohm.io/shop or your local vendor for replacement rods. If
the metal rod degrades, test and correct the soil PH before reinstalling with a new rod.

SETUP AND INSTALLATION

Insert the top of the stake into the cylinder attached to the housing with the wires facing
downward. To release the copper cylinder and rod from their stowaway position, pull the
rod out by pulling down on it from the plastic cap. The rod and cylinder will release.

A) Long-term Installation
The Earthlight™ can be setup in your indoor potted plant for many months or permanently
with proper care and maintenance.
Use the cylinder as a scoop and fill it with soil from the surface of your potted plant. Avoid
debris (rocks, etc.). Compact the soil in the cylinder so that it is nice and firm. Repeat un-
til the cylinder is full and compact. Add a little moisture to the soil if it's too dry to stay in.
About an inch from the edge of the pot, or within the outer 1/3 of the soil, dig a small hole
in the soil with your finger about the depth and width of of the cylinder.
Insert the soil-filled copper cylinder into the hole so that it's top and the plastic cap is flush
with the top of the soil.
With your hand, compact a very small area of soil directly next to the copper cylinder
on any one side. The depth of the compacted soil should mirror the depth of the copper
cylinder and should not be a wide area. An inch or less out from the side of the copper
cylinder will suffice.
Once the soil directly against the copper cylinder is firm on one side and without air
pockets, insert the metal rod into the compacted area directly next to the copper cylinder.
Insert the rod nice and straight so that the plastic cap is touching the copper, but the metal
part is not. Re-compact the soil directly around the rod if necessary.
The Earthlight™ should now illuminate. If it does not, proceed to water your plant as
normally. Make sure to wet the entire soil area evenly, including the area of the copper
cylinder and metal rod. Make sure that the rod is not contacting the copper cylinder.
Insert the plastic stake toward the edge of the pot so that the housing is overhanging and
visible with the wires on the bottom and angle the LED as desired.
If the Earthlight™ still does not light, there is likely a soil quality issue. Consult section
"Amendments" below.

B) Temporary Setup and Field Testing

If a quick soil quality/moisture test of a plant or area is all that is necessary, use this
setup in a potted plant or open soil. This setup may also be used for short-term setup
to test the effectiveness of living soil amendments.
Use the cylinder as a scoop and fill it with soil from the sample area. Avoid debris (rocks,
sticks, etc.). Compact the soil in the cylinder so that it is nice and firm. Repeat until the
cylinder is full and compact. Add a little moisture to the soil if its too dry to stay in.
Insert the metal rod into the middle of the soil within the cylinder. You may have to push
it firmly. Make sure that the rod is straight and not contacting the copper cylinder. Insert
it up to the plastic cap on the same side of the cylinder as the other plastic cap. Press more
soil into the cylinder around the rod so that there is no empty space, only soil.
