HarvestStorm Alpha-1 Instructions

Thank you for your purchase of the HarvestStorm Alpha-1!

This device is an entry-level product to get you familiar with the effects of electroculture stimulation of soil and the surrounding plants.  In essence, the system operates as a pulse generator that provides different amounts of electrical stimulus to the soil and the plants within them, along with varying degrees of delays to give plants a rest from stimulation.


The unit is very simple to operate.  When power is applied to the unit via the enclosed power supply, stimulation turns on.

The unit has a slider switch at the top of the unit that allows for 4 different treatment protocols to be applied:

The frequency that is emitted comes out of the + port on the bottom of the unit.  It comes out of the 3.5mm steel electrode rods that are pre-installed into the unit. 

As the settings are changed, within a few seconds the status light blinking pattern will change indicating the change has taken effect, and the unit will start operating off of the new frequency & delay settings per the table.


If access to a larger electric field is desired, per the directed (linear) stimulation approach below, there are 2 options.  

1) Purchase an Electric Fertilizer Xtender unit that will plug into the expansion port which provides remote ground (-) capability.

2) Purchase a 3.5mm male to female extension of the desired length, (available via contacting ElectricFertilizer or from other sources). Insert the electrode into the female port and install in the ground at the desired remote location.  

With a directed electric field, the electric field will be strongest at the positive end, and weakest at the ground end.  

Replacement Electrodes

Replacement electrodes are standard 3.5mm rod stock that can be purchased at your local hardware store, cut to the desired size.

Radial Electric Field Configuration

The system comes in the form factor allowing for radial electric field generation.  The electric field will travel from the positive to the negative electrode through your grow medium via the shortest path (strongest), and in weaker amounts through longer paths.   

When growing in-soil, you may want to place a piece of plastic between the electrodes to block the field and provide greater distance of the field to the surrounding area.

Linear Electric Field Configuration

If the system you purchased came with one of our Grow Unit Xtenders, then it will allow you to use the system in the linear electric field configuration.  Alternatively, through the use of a 3.5mm audio jack extension cord plugged into one of the electrode outputs, the negative electrode can be used in this configuration by placing the extension electrode some distance away from the main unit.  

Other Configurations

Since the system contains a built-in resistor to protect the device against short-circuits that can occur under extremely wet conditions in highly-conductive soils, you can use that to test out the system in 2 additional configurations.  By connecting an unshielded wire between the positive and negative outputs, you can run the device in "radiated electric field by wire mode" (perhaps there's a better name for this... if you have something, let me know!).  Or, if you use wire that has insulation on it, you can run the device in "radiated magnetic field by wire mode" (again, a name change would probably work well here).  In reality, the 1st mode also has a magnetic field component to it, but will call it the electric field mode for now.

In either of these modes, you will be connecting the outputs together using either a bare or an insulating wire.  The wire should be long enough to be placed into the ground a few inches deep whereby the planted seeds will be very close to the buried wire.  To connect the wire to the output of the device, there are 3 options:

Note:  For all of these cases, only one wire needs to be connected to the ends.  On the device-side, all 3 pins of the 3.5mm jack are connected together.

1) Use a 3.5mm breakout connector:


No soldering needed, just a small screwdriver.

 2) Custom 3.5mm plug

To use this connector, you'll probably have to solder on the wire you want to use.

3) Simply wrap wires around the electrodes

Radiated electric field by wire mode

In this mode, with a bare wire buried underneath the soil, the highest conducting path is along the wire.  Yet there will still be electrical leakage into the surrounding soil and into the seeds / sproutlings adjacent.  At the same time, by the mere flow of electricity through the wire, there will be an induced magnetic field that surrounds the wire.  Since there aren't any loops present, the magnetic field is going to be extremely weak, but may still be effective.  Yet note, it is likely that some amount of electricity is likely to discharge off the wire closest to the source.  This will leave less charge in the wire leaving a reduced magnetic field effect in the wire over the rest of the loop.

Radiated magnetic field by wire mode

In this one, the magnetic aspect of the above mode is all that applies, as there will be no direct conductive electrical path. The difference here is that the magnetic field generated will be constant throughout the loop, most likely resulting in more consistent outcomes.

Operational Caveats 

While electroculture technology has been proven scientifically to provide massive benefits to plants and crops in both fielded and lab-based environments.  Performance is known to be different across plant species, environmental conditions, and stimulation parameter (voltage, current, frequency, timing, etc).  

If the system does not provide you evidence of enhanced growth, consider running up to 4 different cycles to evaluate which of the enclosed protocols provides you with the best results.


ElectricFertilizer takes no responsibility for adverse performance of your crop from the use of our stimulation devices.  This is an experimental technology that is capable of providing massive benefits when everything is in alignment: plant species, growth conditions (soil, moisture, temperature, nutrient/pH balance, etc.

At the end of one or more growth cycles, the positive electrode will contain less material on it through the process of electronic corrosion.  The tip of the electrode, based on the growth medium and the characteristics moisture level against the electrodes, may cause the electrode to become extremely sharp.  Please be warned against cutting or poking yourself while removing or maintaining the electrodes in-ground or during maintenance (replacement). 

Electric Fertilizer bears no risk or responsibility in these and all other domains.
