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.
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)
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
4 x door handle
4 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 upper pair of doors.
The longer (taller) doors are the lower pair.

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.
Link the front and rear
assemblies using the 45 cm
side base parts.
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 assemblies over the
screws on the side base parts
and tighten.

Step 4 - extend the rear uprights
Move the frame down onto the floor at this point.
Parts
2 x joining strap
8 x M5 x 8 button head
8 x M5 square nut
2 x top rear upright 58cm
Insert the 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, and tighten the
lower pair of bolts.
It can be a little fiddly to get the square nuts
to slide into the channels. A small pair of
pliers can help keep them aligned.
Slide the top rear uprights down over the square nuts, and tighten the bolts.
The closed face of the bars faces the rear (outside) of the greenhouse.

Step 5 - Insert square nuts into cross bars
These are for you to attach pipe clips for irrigation (which you may add in the future even if you
donʼt have them now).
Parts
4 x side cross bar 45cm
4 x square nut
Insert a square nut into the inside channel of each
crossbar that will go on the le side of the
greenhouse. The inside channel is the one opposite
the closed face.
Step 6 - Side panels and side crossbars
The top side panel on the le 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:
8 x clear side panel
2 x clear top side panel
4 x side cross bar 45cm
4 x side cross bar with nuts 45cm
Peel the protective plastic off the side
panels. Slot the panels into the frame, one
on each side.
The side with the white film should face
outside; it is the UV treated side.
Slide the crossbars, closed face
outwards, down over the clear side
panels.
The bars with the nuts go on the le side.
Tighten the screws.
Finish inserting all the side panels and
cross bars in the same way.

Step 7 - Front crossbar
Parts:
1 x Front cross bar
(60cm with a black channel top and bottom)
Slide the crossbar into the front of the
greenhouse and tighten when the screws line
up with the holes in the uprights.
Closed face forwards.
Step 8 - Lower rear panel and rear crossbar
Parts:
1 x Lower rear panel (the smaller one)
1 x Rear cross bar (60cm with screws in)
Slide the rear panel into the slots on the rear of
the greenhouse, all the way into the channel in
the bottom base part.
Itʼs a snug fit into the base (anti-slug!); knock it
down gently with a so hammer or block of
wood.
Slide the bar into the rear of the greenhouse.
Closed face backwards.
Tighten the screws from the sides.

Step 9 - 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 10 - 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 11 - 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 12a - Fix bracket to front bar : slot method
Parts:
1 x front upper cross 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 12b - 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 cross bar 60cm
1 x bracket assembly from step 9
2 x M5 x 30mm button head
2 x M5 nut
Bolt the bracket to the front bar, through the
two holes.

Step 13 - Front upper cross bar
Parts
2 x M5 x 30 bolt
2 x M5 nut
2 x M5 washer
1 x front bar you have assembled
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 parts):
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 14 - Fit the shelves
Parts:
Mesh shelves
2 x shelf support per shelf
4 x cable tie per shelf
Slide the square nuts for the 13mm water
pipe to the middle of the crossbars on the le
hand side of the frame, before you insert the
shelf supports.
Slot the shelf supports into the slots on the inside of the
side panel cross bars, inserting them at a diagonal and
then straightening up.
Place the mesh shelves onto the shelf supports and secure
with cable ties, one in each corner.
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 15 - Add the lid prop bolts
Parts
2 x M5 x 16mm bolt
2 x M5 nut
Screw the two standard 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
end panel bar, 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 16 - Fit the lid prop
Parts
1 x lid prop, 405 mm
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 17 - Fit storm lock bolts to right lid side
Position the lid le and right sides on the table. L and R will be marked with the corner cubes
facing towards you. The closed face is upwards.
Parts
1 x right lid sidebar
(45cm with corner cubes)
2 x square nut
2 x M5 x 10mm
1 x o-ring
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 on the right.
Screw the 10mm bolts into the nuts
and tighten them by hand to lock
them in place.
Fit the o-ring over the two bolts on the side of the lid.
The drawing above shows what the lock will look like
when in operation, holding the lid down.
Step 18 -Fit lid side bars to lid rear
This is easiest done on a flat table or worktop.
Parts
1 x lid rear
2 x lid side bars
1. Slide the lid sides into the ends of the ridge assembly, with the closed side upwards.
2. Tighten the screws.
Step 19 - 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 20 - 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 21 - 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).
