Step 1 : Choose where to put your Harvster 

The Harvster needs to be as level as possible, so that the rainwater collection system 
works. A slope of 5% (1 in 20) is just about OK. 

Sunshine 

Put your Harvster somewhere that gets as much sun as possible; grow lights will help 
germinate seeds and provide a bit of top-up light, but they are not a complete substitute for 
the sun. The solar panel (if you’re running off grid) can be placed up to 3m away from the 
main unit. 

Power 

Mains power is not needed unless you add heaters and/or grow lights. If you do add mains 
power, you will need to work with a registered electrician to install an outside power 
socket, or position your Harvster within 5m of an indoor power socket. The mains powered 
Harvst control units come with 5m of cable. 

Water 

If you have a garden hose, you can run a tee’d connection to your Harvster. It can be as far 
as you like from the tap. 
 
If you don’t have a hose, you’ll need a pump, and a water tank of some sort. You can use 
the Harvster tank, or a water butt if there’s one within 2m of your Harvster. If you live in an 
area that doesn’t get much rain, you might want to consider running a gutter offshoot from 
another roof onto your Harvster to collect more rainwater. 

Base 

Harvsters can be placed directly on the ground, on an existing raised bed, or on one of our 
Harvster raised beds. Consider how much soil depth you want to have for your plants. At 
least 25cm (10”) is wise for many vegetables that are suitable for growing in a Harvster.  
 
A 40cm raised bed under the largest Harvster (1.2m * 2m / 4’ * 7’) will take about 500kg of 
soil / compost. That’s about 10 wheelbarrows full - this will vary based on the type of soil 
you get and how moist it is.  
 
Containers are great for growing in; the Harvster is designed to take standard 600mm euro 
stacking crates.
