Introduction - slotting parts together
The greenhouse is based on parts that slot together using 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.
Every care has been taken during manufacture to avoid sharp edges or burrs, however you
should still take care when handling metal parts.
WARNING DO NOT USE POWER TOOLS TO SCREW IN THE SCREWS. YOU MIGHT SNAP OFF
THE HEAD, WHICH IS NOT COVERED BY WARRANTY.
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 - Fit the door handles
Do this step first to allow the adhesive tape to cure before fitting 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, that the surfaces are clean, dry and free from grease, and
that the UV treated side of the door panels (white film) faces
out.

Step 3 - Assemble the base
Parts:
1 x front assembly
1 x rear assembly
2 x side base 45cm
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 closed faces on the
assembly uprights face
outside the
greenhouse.
The side base parts
have the single channel
facing up, and the
double channel facing
down.
Slot the front assembly over the screws on the
side base parts and tighten the screws.
Do the same for the rear assembly.

Step 4 - Insert square nuts into cross bars
Parts
2 x side cross bar 45cm
2 x square nut
Insert a square nut into the inside channel of each
cross bar that will go on the le side of the
greenhouse.
The inside channel is the one opposite the closed
face.
These nuts are for irrigation parts which you may or
may not add in the future.
Step 5 - Insert the side panels and side cross bars
The upper le side panel has a hole with grommets 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, two with nuts
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.
Insert the bottom two clear side panels.
Slide a bar with nut over the le panel.
Slide a bar without nut over the right panel.
Tighten the screws.
Finish inserting all the side panels and cross
bars in the same way.

Step 6 - Fit the right side panel top assembly
Parts:
1 x Right side panel top assembly
3 x M5 * 8mm button head bolt
3 x M5 square nut
1 x M5 * 10mm button head bolt
Insert the 8mm bolts into the
assembly in positions marked 1,2,3,
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.
Screw the 10mm bolt into the square nut which is already in the outside channel of the assembly
and tighten by hand. This will form part of the storm lock (see end of guide)
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.
Step 7 - Fit the le side panel top assembly
Parts:
1 x Right side panel top assembly
3 x M5 * 8mm button head bolt
3 x M5 square nut
Repeat for the le hand side
(apart from the storm lock bolt which is only on the right
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 60cm
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
place.
Parts:
1 x front upper bar 60cm
1 x bracket assembly from step 9
2 x M5 x 30mm bolt
2 x M5 nut
Bolt the bracket to the front bar, through the
two holes.

Step 10 - Insert the front crossbar
Parts
2 x M5 x 30mm 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.
Tighten securely.
Optional step - fit pipe clips
If you have a greenhouse with self watering, it will be easiest to fit the pipe clips before adding
the mesh shelves.
Parts (from control
system kit):
4 x pipe clip
4 x M5 x 16mm bolt
Fit the pipe clips to the crossbars as shown in the drawing above. The irrigation down-pipe will
clip into these.

Step 11a - Fit the shelves (greenhouse, solar and 3-season)
One mesh shelf is supplied as standard for the greenhouse-only and solar models. Two mesh
shelves are supplied with the 4-season model, since the additional lighting allows plants to be
grown closer together.
Parts, per shelf
2 x shelf support
1 x mesh shelf
4 x cable tie
Slot the shelf supports into the slots on the inside of the side
panel cross bars.
Place the mesh shelves onto the shelf supports and secure
with cable ties.
NOTE: The mesh shelf with a slot cut out goes in the top level to allow the lid lier piston to
swing clearly. The front shelf support goes in upside down.

Step 11b (4-season model with LED lights)
1. Slot the combination shelf support / LED lights into the side cross bars in the same way
as in step 10a above, with the wires coming out of the le hand side.
2. Secure the mesh shelves to the lights using the cable tie holes.
If you have heater cables, leave the attachment of the mesh shelves until aer you have added
the heating cable.
If you donʼt have heater cables, place the mesh shelves onto the shelf supports and secure them
with cable ties.
Step 12 - Install rear panel
Parts
1 x rear panel
Drop the rear panel into the inner slots of the
rear uprights.
Ensure it goes fully into the lower base part -
itʼs a tight fit.

Step 13 - Add the lid prop support bolts
Parts
2 x M5 x 16mm button head bolt
2 x M5 nut
The nyloc nut has a little plastic
ring inside to prevent it loosening
over time.
Screw the two nuts onto the bolts until they are 2mm
away from being fully tightened.
Slide the heads of the bolts down the inner slot on the
top right of the greenhouse, as shown in the drawing
below.
Slide one all the way to 40mm off the bottom and leave
the other one near the top.
Holding the bolt thread, tighten the nut to create a stud.
The lower / front stud goes through the lid prop with a
nyloc nut on it.
The top / rear stud is used to rest the lid prop when not
in use.
Step 14 - Fit the lid prop
Parts
1 x lid prop, 40cm
1 x M5 nyloc nut
Note: The nyloc nut has a little plastic ring
inside to prevent it loosening over time.
Put the hole in the lid prop over the lower
stud that you inserted above.
Put on the nyloc nut, tightening it just so that
the plastic “bites” the thread. The prop
should be loose enough to move around.

Step 15 - Lid side bars
This is easiest done on a flat table or worktop.
Parts
1 x lid rear
2 x square nut
2 x M5 x 10mm
2 x lid sidebar 45cm with corner cubes
1 x o-ring
Le and Right lid sides will be marked with the corner cubes facing towards you, as per the
drawing above.
1. Slide two square nuts into the outside channel of the right lid sidebar. These will form
the top bolts for the storm lock as per drawing below.
2. Screw the 10mm bolts into the nuts and tighten them by hand to lock them in place.
3. Fit the o-ring over the two bolts on the side of the lid. This is what the lock will look like
when in operation, holding the lid down:
1. Slide the lid sides into the ends of the lid rear, with the closed side upwards.
2. Tighten the screws.
Step 16 - Insert the lid polycarbonate
Parts
1 x clear lid panel
Slot in the lid polycarbonate sheet, with the holes at the front.
Make sure the white UV protected side is upwards.
Youʼll need to flex the lid side bars apart slightly.

Step 17 - Complete the lid
Parts
1 x lid front bar
2 x 30mm screw
Screw the front of the lid
onto the rest of the lid
assembly, with the closed
face up.
Step 18 - Fit the lid lier to the lid
Place the lid upside down on a table (with the black channel facing up), with the holes over
the edge.
Parts:
2 x M4 x 16mm bolt
2 x M4 nut
1 x lid top plate
1 x lid lier
Place the lid lier so that the bracket with slots in is above the
two holes in the front of the lid.
The slotted bracket is shown in the diagram above without the
lid lier, for clarity.
Bolt the lid lier to the bottom of the lid, using the top plate on
the other side (underneath the upturned lid).

Step 19 - Fit lier piston
WARNING - the lid lier has powerful springs and should be treated with care.
Parts
1 x lid lier piston
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. Watch a video at
www.harvst.co.uk/setup for more tips.
Step 20 - Fit the ridge to the lid
Parts
1 x assembled lid
1 x ridge
2 x plugs
Fit the blanking plugs when
the screws are fully
tightened.
Step 21 - Fit the lid
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.
Before you tighten the screws, ensure
the sides of the greenhouse are firmly
pushed together to secure the rear
panels in place.
Tighten the screws well.

Step 22 - Fit the doors
Parts
2 x polycarbonate door
With handles fitted
Pop the doors into the sliding channels by flexing them slightly.
The le hand door goes in the rear (inside) channel and the right
hand door goes in the front (outside) channel. Refer to the door
drawing at the beginning of the guide.
Tip: If the doors are too tight, you can loosen the crossbar mounting bolts to let the bar come up
a little. Tighten them in a suitable position so that the doors slide well.
Step 23 - 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.
Step 24 - Secure the greenhouse down
If you are in an exposed location, we recommend that you secure the greenhouse to the ground,
a wall or a fence.
Parts
2 x Angle bracket
2 x Square nut
2 x M5 x 8mm bolt
Use the spare square nuts in the rear upright side slots, with an M5 x
8mm bolt and the stainless steel angle bracket (or a bracket of your
choice to suit what youʼre mounting to)

Storm lock
In very strong winds, you may want to lock the lid so that it doesnʼt blow open. The o-ring fitted
to the right side of the lid should be stretched over the frame bolt as shown below:
Note: When the storm lock is fitted, you must disengage the automatic lid lier from the pegs
on the lower mounting bracket.
Regular maintenance
The materials and design of your greenhouse means that it does not need much maintenance.
●The automatic lid lier will need oiling from time to time to prevent corrosion.
●Clean the inside of the panels from time to time, especially if you have hard water.
To extend the life of your automatic lid lier, avoid opening the lid against the pressure of the
piston too frequently. Open the front doors, unclip the lier mechanism, and then open the
lid. The lid opener piston is not covered under our manufacturer's guarantee.
