Connect the control unit to WiFi
We recommend you do this indoors, before you install the control box into your
greenhouse, polytunnel or cold frame. When it’s working indoors, you can move it to
the site where you’re going to put your greenhouse to test the connection there before
you begin construction of the frame.
1. Ensure your WiFi network name and password are handy.
2. Turn on your Harvst control unit. It will start beeping fast and the red LED will
be on.
3. If, after 10 seconds, no previous WiFi connection has been found, the unit will
start beeping slowly; once a second. It has just started it’s own WiFi signal.
4. On your phone, go to WiFi settings, and connect to the "harvst-wifi" access
point. You should be automatically redirected to http://192.168.4.1 *
5. Click the blue "Configure WiFi" button.
6. You should see your WiFi network listed. Choose your WiFi network by clicking
its name. If you don't see yours, click "Refresh".
7. Enter your password and click save.
8. The unit will pause for a while and then if it connects OK, you'll hear a double
beep. You’ll also get a welcome text message to your phone.
If you run out of time, haven’t received the welcome text message or email, or have any
other trouble connecting, turn the unit off and then back on again to restart the WiFi
connection process. WiFi details will be stored for the next time you turn the unit on.
* If you’re NOT redirected automatically to the setup screen once you have connected
to harst-wifi, then open a browser (Chrome, Safari etc) and type in “192.168.4.1” to the
address bar; where you would normally enter a website address. This will take you to
the blue “Configure Wifi” button.

1. Prepare the location
Your greenhouse will need level ground to sit on. You can put it directly on grass, on a
raised bed, or a hard standing like concrete or brick. If your foundation is not flat and
level, your lid and doors won't operate smoothly, so it's worth putting the effort in
now.
The rainwater collection system also requires a flat and level base. A slope of 5% (1 in
20) is just about OK.
Sunshine
Put your greenhouse 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 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 greenhouse 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 connection to your greenhouse. 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 Harvst tank, or a water butt if there’s one within 2m of your greenhouse. 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 greenhouse to collect more rainwater.
Base
Harvst greenhouses can be placed directly on the ground, on an existing raised bed, or
on one built especially for it. 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
Harvst mini greenhouse.
A 40cm raised bed under the largest Harvst greenhouse (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 greenhouse is designed to take standard
600mm euro stacking crates.
2. Attach baseboards to end panels
Parts
2 x pre-assembled end panel
2 x timber base board
8 x 50mm furniture bolt
The base board with the double black
plastic track is on the front of the
greenhouse. The ribs on the timber
face out.
The base board with the single black
plastic track is on the back.
Attach the timber base boards to the
end panels, using the furniture bolts.
Tighten well.
3. Fit the rear shelves
Parts
2 x 30mm aluminium shelf
4 x 20mm M5 bolt and nut
The rear shelves (without the irrigation
pipe) are fitted to the bottom of the
plastic blocks using a single bolt at the
end of each shelf.
The bolt goes down through the plastic
block, through the shelf and is secured
with a nut underneath the shelf.
4. Fit the front shelves
Parts
2 x Front shelf
4 x 20mm M5 bolt and nut
The front shelves are the angle
aluminium with a black pipe attached
via pipe clips.
The bottom shelf is the one with the
open ended pipe on the right.
The top shelf is the one with the end
stop (closed pipe) on the right.
The twin water valves will fit on the
bottom right hand side in the next
step.
Fit to the brackets in the same way as
you fitted the rear shelves, and do the
nuts up tightly.
5. Fit water valves
Parts
1 x twin water valves
See photos at www.harvst.co.uk/setup
Fit the water valves to the right end of
the pipe on the bottom front shelf. The
snap-on hose connector faces
backwards towards the rear of the
greenhouse, so that the bottom outlet
plugs into the front shelf pipe. Secure
the valve to the pipe with a jubilee clip.
In the drawing you can also see a green
pipe going upwards, you will fit this
later (it’s black in real life).
6. Fit connecting hose
Fit the short (approx 50cm) section of
black hose between the elbow joints on
the top and bottom pipes, on the left.
The hose runs around the front of the
bottom shelf (the side closest to the
doors).
TIP
: You will need to warm the ends of
the hose in hot water for a few seconds
to soften it before fitting.
Parts
1 x connecting hose
7. Fit the rear panels
2 x Black rear panel
3 x 20mm wide black
connecting strip
2 x 1440mm long H-section
2 x 20mm M4 bolt, penny
washer and nut
Put the penny washer on the outside.
Fit the panels so that the holes for the
control system are at top right.
From behind, drop the two large
panels into the slot on the timber base,
and outwards into the slots in the end
panel uprights.
Slide the H-section down on the inner
sides of the end panels. It doesn't
matter whether the long leg is inside or
outside.
Next, fit the three thin black strips. The
long one goes in first. Slide them down
the gap to tighten it all up. Leave gaps
between the strips, at the hole in the
centre of each shelf, for the bolts which
hold the panels to the frame.
We've found the best way is to slide up
one of the large panels so you can get a
hand inside to fit the nut on the bolt.
8. Fit front cross bar and doors
First, drop the crossbar into the brackets
on the front of the end panels.
The bracket for the lid opener faces
backwards, inside the unit.
Then put the doors in; you'll need to lift
the cross bar slightly.
The left hand door goes on the
rearmost track. The right hand door
(with both handles fitted the same way)
goes in the front track:
Parts
1 x Crossbar : 25mm box
section with twin black
plastic track
2 x M5 40mm bolt and nuts
2 x Door panel
1 x Door handle
2 x M5 16mm bolt and nuts
On the left hand door, you’ll see two
holes for mounting the small handle.
Bolt the handle to the door using two
M5 * 16mm bolts, with a washer and
nut on the inside of the door.
The right hand door doesn’t have a
small handle; you can use the long
handle attached to the side of the
door.
The right hand door has a sticker on
the top right.
Bolt the crossbar in place using the
40mm bolts and nuts.
