Panels
Tools provided

8mm spanner
Pozidrive screwdriver
Tools required
Tape measure to check parts
Secateurs for cutting pipe
You will also have mesh shelves, the quantity
depending on which model you have bought.

Slotting parts together
The greenhouse is based on parts that slot together using 30mm stainless steel screws, as shown
in the diagram below.
Ensure that your screwdriver is
fully engaged with the screw
head when you tighten, so that
you donʼt round off the head of
the screw.
Note the orientation of each
piece in the description;
specifically the closed face.
WARNING Every care has been taken during manufacture to avoid sharp edges or burrs,
however you should still take care when handling metal parts.
Step 1 - Seal the polycarbonate panels (optional)
Twin wall polycarbonate panels act like double glazing for your mini greenhouse, and to improve
the insulation characteristics, it is good to seal the ends of the channels using the provided foil
tape. It also helps prevent bugs from crawling into the plastic.
This step is optional - it can take some time but is recommended.
1. Peel back a couple of inches of the protective foil which covers both sides of the panels,
but donʼt take it all the way off yet.
2. Apply the tape to the end of the panel, covering the flutes.
3. Fold down the sides to seal the tape to the panels.
The white film is on the UV protected side which should face out when you place the panels into
the greenhouse.

Step 2 - Attach the door handles
Do this step first to allow the adhesive tape to cure while you assemble the rest of the
greenhouse. Youʼll fit the doors at the end.
Parts
2 x door handle
2 x polycarbonate door
Fix the door handles to the doors as shown in the drawing
above, using the tape fixed to the handles.
Make sure you have peeled the protective film off the doors
first, the surfaces are clean, dry and free from grease, and that
the UV treated side of the door panels (white film) faces out.
There is a sticker on the right door.
Step 3 - Fit weather seal
Parts
1 x self adhesive weather strip
Fix the weather strips to the inside of the right hand door,
as shown on the drawing above.

Step 4 - Assemble the base
Parts:
1 x le assembly
1 x right assembly
1 x front base 121cm
1 x rear base 121cm
This step is best done
on a flat surface where
you can easily access
the screws at the
bottom, such as a
table or workbench.
The le and right
assemblies are
interchangeable.
The rear base part has
the single channel
facing up, and the front
has the double
channel facing up.
Slot the le and right assemblies over the
screws on the front and rear base parts and
tighten the screws.

Step 5 - Insert square nuts to side cross bars
Parts
4 x side cross bar 45cm
10 x square nut
Insert three square nuts into the inside channel of
each cross bar that will go on the le side of the
greenhouse.
Two will be for the shelves, and the third will be for
supporting the irrigation pipe (itʼs worth fitting the
nuts now even if you donʼt have the irrigation kit yet).
The inside channel is the one opposite the closed
face.
Insert two square nuts into the inside channel of the
right hand cross bars.
Step 6 - Insert the side panels and side cross bars
The top side panel on the le has a hole with a grommet in it for an external hose or tank
connection, if you have a solar, 3-season or 4-season model.
Parts:
4 x clear side panel
4 x side cross bar 45cm
Peel the protective plastic off both
sides of two side panels, remembering
which side had the white film.
The side with the white film should
face outside; it is the UV treated
side.
Slot the panels into the frame, then
slide the bars, closed face outwards,
down over the clear side panel.
Tighten the screws. Repeat for the
other side.
Finish inserting all the side panels and
cross bars in the same way.

Step 7 - Fit the side panel top assemblies
Parts:
1 x Right side panel top assembly
3 x M5 * 8mm button head bolt
3 x M5 square nut
Insert the bolts into the assembly,
and add the square nuts on the
inside, loosely.
Slide the assembly down over the
side panel, inserting the square
nuts into the outer channels on the
uprights.
The front end goes down as far as it will go, and the rear end is flush with the top of the rear
upright (see drawing below).
Tighten the bolts.
Repeat for the le hand side.

Step 8 - Fix lid lier bracket to adapter plate
OPTIONAL - if you have an automatic lid opener
The lid lier bracket is in the lid opener box. (see drawing below for named parts)
Parts:
1 x lid lier bracket
1 x adapter plate
2 x M5 x 8mm button head
2 x M5 nut
Bolt the lier bracket to the adapter plate as
shown, with the nuts on the inside of the
bracket.
Step 9a - Fix bracket to front bar : slot method
Parts:
1 x front upper bar 121cm
1 x bracket assembly from above
2 x M5 x 8mm button head
2 x M5 square nut
Slide two square nuts into the
rear channel of the bar (the side
opposite the closed face). Bolt
the bracket assembly to the front
bar, in the exact centre of the bar.
Step 9b - Through-hole method
If your greenhouse has a front crossbar with no slot, it will have holes drilled in the relevant
places.
Parts:
1 x front upper bar 121cm
1 x bracket assembly from step 9
2 x M5 x 30mm button head
2 x M5 nut
2 x M5 washer
Bolt the bracket to the front bar, through the
two holes using the 30mm bolts, washers
and nuts.

Step 10 - Add the lid prop bolt
This is the pivot bolt for the lid prop.
Parts:
1 x M5 x 40mm bolt
1 x M5 nut
Put the bolt through the hole just to the right of the middle of
the crossbar, from the front (the lid lier bracket is on the rear).
Secure it with the nut.
Step 11 - Insert the front crossbar
Parts
1 x M5 x 30mm bolt
1 x M5 x 40mm bolt
2 x M5 nut
2 x M5 washer
Bolt the front upper bar to the rear of the
brackets on the front of the greenhouse.
The 40mm bolt goes on the right hand side
to act as a support for the lid prop which
you will add later.
Tighten securely.
Step 12 - Fit the shelf brackets to the frame
Parts (per shelf)
4 x M5 x 8mm cap head bolt
4 x shelf angle bracket
Screw the brackets loosely onto the
cross-bars of the end panels, using the
M5x8mm bolts and the nuts in the channels
of the cross bars.

Step 13 - Fit the shelf support bars
More shelves are supplied with the 4-season model, since the additional lighting allows plants to
be grown closer together. For the 3-season, Solar and Greenhouse-only models, choose where
you would like your shelves to be.
The top shelf support is mounted upside down and takes the narrower mesh panels, to allow
the lid lier piston to swing clearly.
Parts, per shelf level
4 x M5 x 8mm cap head bolt
4 x M5 nut
2 x angle aluminium, 121cm
Fix the shelf loosely to the bottom of the
bracket, using another M5x8mm bolt and a
nut underneath.
Push the shelf as far back as it will go,
without obstructing the channel on the
inside of the rear upright; this slot is where
the rear panels will fit.
Tighten all the bolts with the 4mm allen key.
< Side view showing

with the front shelf
support mounted upside
down.

Step 14 - Install irrigation system (optional)
Self watering is provided either by sprayers or drippers, depending on what you want to grow
and how you would like to water it.
For sprayers, our
recommended setup is one
set of five sprayers under
each shelf, watering the
plants below.
The thin hose and sprayers
are fixed to the mesh shelf
with cable ties.
The top shelf can be watered
with drippers, or you can add
further 4mm hoses into the
riser pipe as you see fit.
You can replace one or all of
the sprayers with pressure
compensated drippers, or
any other standard 4mm
micro irrigation part.
Example setup. See website for irrigation details.
See our website for a range of videos which show you how to connect up various different
water sources to your greenhouse irrigation. www.harvst.co.uk/setup

Step 15 - Fit the grow lights - optional
The 4-Season greenhouses can be fitted with grow lights. Up to a maximum of eight per control
unit output (see notes on control unit maximum capacity).
Per shelf:
2 x light bar
8 x cable tie
With the cables on the le, fix the lights to the underside of the
mesh shelves using cable ties through the small holes.
Extra light pairs
Extra splitters
For each pair of lights, connect a 3-way splitter to the lights,
leaving a spare socket to connect to the shelf below.
Connect the lights to the control unit later.
Step 16 - Fit the heater cable(s) - optional
Parts
Heater cable(s)
100mm cable ties
Plug the heater cable(s) into the control box as described in
the control system setup guide.
Weave the cable in and out of the shelf mesh, to provide a
heated platform on which you place your growing containers.
The cable will reach a maximum of 60 degrees C which will not
damage any of the greenhouse frame or plastic.

Step 17 - Install rear panels
Parts
2 x rear panel
1 x PVC H-trim 84cm
2 x long cable tie
Insert the two rear panels with the drilled panel on the le.
If you have a control system to install, complete the next step
before inserting the section of H-trim between the panels.
Step 18 - Fix controls to le rear panel
Parts
2 x M5 x 16mm bolt
2 x M5 washer
2 x M5 nut
Fit the control unit to the rear panel using the 2 holes at the top le
of the panel. Flip the mounting hole covers up on the control unit
to expose the mounting holes. Itʼs easiest to hold the bolts on the
allen key as you push them through the control unit.
Parts
2 x M4 x 16mm bolt
2 x M4 penny washer
2 x M4 nut
Optional : power supply (mains version) : Fit the power supply to
the rear panel using the two holes to the right of the control unit.
The long mains cable goes on the right.
Feed the power cable out through the slot in the rear panel.
Step 19 - Fit the doors
Parts
2 x polycarbonate door
With handles fitted
Flex the doors slightly and pop them into the channels on the
front base.
The le hand door goes in the rear (inside) channel and the right
hand door goes in the front (outside) channel.

Step 20 - Fit the lid prop
Parts
1 x lid prop, 55cm
1 x M5 nyloc nut
Note: The nyloc nut has a little plastic ring
inside to prevent it loosening.
Put the hole in the lid prop over the stud
formed by the bolt on the front crossbar.
Put on the nyloc nut, tightening it just so that
the plastic “bites” the thread. The prop
should be loose enough to move around.
The right hand end of the lid prop rests on the bolt which secures the front bar.
Step 21 - Lid centre bar
This is easiest done on a flat table or worktop.
Parts
1 x hinged ridge assembly
1 x lid centre bar 44cm
2 x square nut
Place the ridge piece with
the black plastic channel
facing down.
Slide the lid centre bar into
the ridge piece (the 20mm
square section), with the
closed side upwards.
Slide the square nuts into the channel opposite the closed
face.
These will hold the automatic lid opener arm.
Tighten the screw at the back.
Step 22 - Lid side bars
Parts
1 x hinged ridge assembly
2 x lid sidebar 44cm
With plastic corner pieces
Slide the lid side bars into
the ends of the front of the
ridge piece, with the closed
side upwards.
Note: The stubs on the plastic corner pieces face inwards,
towards each other.
Tighten the screws.

Step 23 - Insert the lid polycarbonate
Parts
2 x clear lid panel
Slot in the lid polycarbonate sheets.
Make sure the white UV protected side is upwards.
Youʼll need to flex the lid side bars apart slightly.
Step 24 - Fit the lid front bar
Parts
1 x lid front bar 121cm
2 x 30mm screw
Screw the front of the lid
onto the rest of the lid
assembly, with the closed
face up.
Step 25 - Fit the lier arm plate to the lid lier
Parts:
2 x M4 x 12mm bolt
2 x M4 nut
1 x lier arm plate
1 x lid lier
Open the lid lier box and remove the small parts from
the bag.
Fit the lid lier bracket (at the end of the sprung arm)
to the lier arm plate.

Step 26 - Fit the lid lier to the lid
Parts:
2 x M5 x 8mm bolt
1 x lid lier
Turn the lid upside down.
The two square nuts in the centre channel will now be visible.
Refer to the drawing above and fix the lier arm plate to the
square nuts using the bolts, with a 15mm gap to the front bar.
Step 27 - Fit the lid to the greenhouse
Parts
2 x 30mm screw
1 x Lid
Place the lid on top of the greenhouse, making sure that the rear
panel slots into the black channel on the underside of the lid.
Secure it with two 30mm screws into the rear uprights.
Step 28 - Fit lier piston
Parts
1 x lid lier piston
Prop the greenhouse lid open using the lid prop. Insert the black
piston into the lid lier, using the instructions as supplied with the
lid lier.
Taking care not to trap your fingers, squeeze the sides of the lid lier together and insert the
studs into the bracket on the inside of the front upper bar.
Step 29 - Fit the hole caps
Weʼve supplied some small black plastic caps to cover the screw holes in the front of the
greenhouse to make it look smarter. Nowʼs the time to fit the caps, sit back and have a cup of tea.
