Slotting parts together
The greenhouse is based on parts that slot together using 30mm stainless steel screws, as shown
in the diagram below. These are self tapping screws which require a little bit of force to get them
fully seated.
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.
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)
This step is optional, but is recommended.
Twin wall polycarbonate panels act like double glazing for your mini greenhouse. To improve the
insulation characteristics, itʼs good to seal the ends of the channels using the foil tape provided.
It also helps prevent bugs from crawling into the plastic.
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 / open ends.
3. Fold down the sides to seal the tape to the panels.
The white film is on the UV protected side which should face outwards when you place the
panels into the greenhouse.
Step 2 - Assembling the base
Parts:
1 x le assembly
1 x right assembly
1 x front base 121cm
1 x rear base 121cm
The le and right
assemblies are
interchangeable.
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.
NOTE:
The rear base part has
the single channel
facing up, and the
front has the double
channel facing up.
10

Slot the le and right assemblies over the
screws on the front and rear base parts and
tighten the screws using the screwdriver.
11

Step 3 - Fit the rear upright joining straps
Move the frame down onto the floor.
Parts
2 x joining strap
8 x M5 x 8 button head
8 x M5 square nu5
2 x top rear upright 55.8cm
Insert the 8mm bolts into the joining straps, and put a
square nut on the back of each, loosely.
Slide the square nuts into the outside channel of the
rear uprights.
The outside channel is the far le or far right channel;
the joining straps will be on the outside of the
greenhouse.
Tighten the lower pair of bolts.
12

Step 4 - Fit the top rear uprights
Parts
2 x top rear upright 55.8cm
With the holes as shown in the drawing below, slide the top rear
uprights down over the joining straps.
The closed face should be to the rear of the greenhouse.
Tighten the upper pair of bolts.
Step 5 - Insert square nuts to side cross bars
Parts
8 x side cross bar 45cm
8 x square nuts
Insert square nuts into the inside channel of each cross bar according to the following quantities
per cross bar:
- 3 lengths with 1 square nut
- 1 length with 3 square nuts
- 1 length with 2 square nuts
Please refer to the diagram in step 6 for reference.
13

Step 6 - Insert the side panels and side cross bars
Parts:
8 x clear side panel
8 x side cross bar 45cm
2 x top clear side panel. Two holes in the Le
panel
Note the sequence of cross bars, with
the number of nuts in the diagram
below.
Peel the protective plastic off both sides of
the side panels, remembering which side has
the white film; it should face outside as it is
UV treated.
Slot two panels into the frame, one on each
side.
Slide the bars, closed face outwards, down
over the clear side panels. Tighten the
screws.
Finish inserting all the side panels and cross
bars in the same way.
The top le panel has two holes, for
greenhouses with automated watering.
14

Step 7 - 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 lower 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 for more
info.) Ensure the second square nut in the channel is further up towards the rear of the
extrusion.
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).
Tighten the bolts.
Step 8 - Fit the le side panel top assembly
Repeat step 7 for the le hand side.
15

Step 9 - Fix lid lier bracket to adapter plate
This step is only relevant if you have purchased an automatic lid opener.
Parts in Lier Box :
1 x Piston Clip (end of box)
1 x Piston
1 x Arm
1 x Lier Bracket
The lid lier bracket is in the lid opener box.
Parts needed for Step 9:
1 x lid lier bracket
1 x adapter plate
2 x M5 x 10mm button head
2 x M5 nyloc nut
Bolt the lier bracket to the adapter plate as
shown in the diagram to the right, with the
nyloc nuts on the inside of the bracket.
Step 10 - Fix bracket to front crossbar
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 (the side opposite
the closed face). Bolt the bracket
assembly in the exact centre of
the bar.
16

Step 11 - Insert the front crossbar
Parts
2 x M5 x 30mm bolt
2 x M5 nyloc nut
2 x M5 washer
Bolt the front crossbar to the rear of the
brackets on the front of the greenhouse,
using the M5 x 30 bolts through the front.
Fix them in place with a washer and nyloc
nut on the rear.
Tighten by hand (youʼll remove one bolt
later to li the crossbar to fit the doors).
17

Step 12 - Understand how the shelves fit
Refer to the drawing below to see which shelves are bolted and which shelves simply slot into
the greenhouse only frame.
Note: If you have a 4 seasons model please refer to your smart control guide for layout of
additional shelves.
A short section of 4mm tube pressed into the channel prevents the front shelf from sliding
forwards. When the mesh shelves are in place, the other shelf supports will not slide out.
Use 160mm in front of the top shelf and 90mm in the rest that arenʼt bolted in.
18

Step 13 - Fit the shelf supports
The shelf with the double holes half way along is fitted to the rear of the greenhouse.
The shelf without the holes is fitted to the front. This step can be easier with an additional pair
of hands to support the bars whilst positioning.
Parts
4 x M5 x 8mm cap head bolt
4 x M5 nyloc nut
1 x pair drilled shelf supports 121cm
4 x shelf angle bracket
Tools
4mm allen key
8mm spanner
Fix the shelf angle brackets to your drilled
shelves using the m5 x 8 cap head bolts and
m5 nyloc nuts. Tighten up just enough so
that there is some movement to make the
next step easier.
Step 14 - Fit assemblies from step 13 to your frame
Parts
4 x M5 x 8mm cap head bolt
NOTE: Where the end panel has three
nuts, leave the middle one unused.
Locate the square nuts in the 45cm sidebar
channel and secure the shelf supports from
step 14 using the m5 x 8 cap head bolts.
Fit the rear shelf bar assembly so the shelf
support vertical face is flush with the frame
upright as pictured below..
With the rear shelf bar in place use a mesh
panel to ensure the correct spacing between
the front and rear shelf bars. Alternatively
use a tape measure and measure 14”
distance between the two.
19

Top tip: Once you have the bolted shelf supports in place, use a long strip of masking tape (or
similar) across the back of the greenhouse to hold the sides vertical.
Without the tape there is a tendency for the sides to splay out, and the slotted shelf supports
and rear panels may fall out. When the lid is screwed on later, you can remove the tape.
