Introduction - 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.
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 - 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 - Fit the door seal
Parts
1 x self adhesive weather strip
Fix the brush weather strip / seal to the inside of the right
hand door, as shown on the drawing above.

Step 4 - 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 5 - 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 6 - Insert the side panels and side cross bars
The lower le side panel has a hole with a grommet in it for an external hose or tank
connection, if you have a solar or 4-season model. The hole is at the top rear of the panel.
Greenhouses with irrigation will have a hole
in one panel. Place this at bottom le.
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.
Slot two panels into the frame, one on each
side. The bars with nuts are on the le.
Slide the bar, 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 x 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
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 35 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.
Step 11 - Fit the shelves
One shelf is supplied as standard for the greenhouse-only and Eco models. Two 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.
The narrower shelf goes in the top slots to allow the lid lier piston to swing clearly. We
recommend putting the front shelf support in upside down to make tray removal easier.

Step 12 - 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. Using standard 4mm micro irrigation pipe, you can choose to
use sprayers under the shelves of the greenhouse, or use drippers instead to feed the soil without
getting leaves wet.
Water can be provided by your choice of:
●Garden hose with an external tap timer
●Garden hose with a Harvst smart controller and electric valves
●Harvst smart controller with water pump
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 13 - Fit the grow lights - optional
The 3-season and 4-season greenhouses can be fitted with grow lights. Up to a maximum of six
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 14 - Fit the heater cable(s) - optional
Parts
Heater cable(s)
100mm cable ties
Fit one heater cable to the top socket on the le hand side of
the control unit. If you have a second heater cable, it goes in
the middle socket.
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 65 degrees C which will not
damage any of the greenhouse frame or plastic.

Step 15 - Fix controls to rear panel
If you have a greenhouse with a control system, mount the control unit (and power supply) to
the rear panel before inserting into the greenhouse, so you can feed the power cable through the
side slot before dropping the panel in.
Parts
2 x M5 x 20mm 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 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 16 - 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 17 - Add the lid prop support bolts
Parts
2 x M5 x 16mm button head bolt
2 x M5 nut
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
nylock nut on it.
The top / rear stud is used to rest the lid prop when not
in use.
Step 18 - Fit the lid prop
Parts
1 x lid prop, 42cm
1 x M5 nylock nut
Note: The nylock 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 nylock nut, tightening it just so
that the plastic “bites” the thread. The prop
should be loose enough to move around.

Step 19 - Lid side bars
This is easiest done on a flat table or worktop.
Parts
1 x hinged ridge assembly
2 x lid sidebar 44cm
With plastic corner pieces
Place the ridge piece with
the black plastic channel
facing down.
Slide the lid side bars into
the ends of the front of the
ridge piece (the 20mm
square section), with the
closed side upwards.
Note: The stubs on the plastic corner pieces face inwards,
towards each other.
Tighten the screws.
Step 20 - 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 21 - 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 22 - 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 23 - 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
Prop the greenhouse lid open. 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 24 - 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.
Step 25 - 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.
Step 26 - 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 27 - 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)

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.
