How to build a propagation table
This propagation station is waist height for ease of use, and has weather-resistant UV plastic and mesh sides for ventilation. It’s possible to adapt these plans by upcycling an old barbecue frame and repurposing a disused outdoor table as the stand. An o

18m of 45 x 45mm gauged wood, cut into lengths of 4 x 1m, 4 x 1.2m, 6 x 300mm, 4 x 1110mm and 2 x 390mm

Stand STEP 1
For each front and back frame side, vertically lay 2 x 1m lengths of 45 x 45mm and place 2 x 1.2m lengths horizontally on top: one 45mm and one 670mm from base of verticals. Affix each connecting length with 2 x 75mm screws.
Stand frames upright to face each other (the horizontal lengths facing inwards). Chock with blocks so they stand self-supported.
Shelves STEP 3
Cut decking into 22 lengths of 390mm slats. To make the lower shelf, place 11 slats between the front and back frames, on lower horizontal supports. Evenly space slats (about 12mm between each), adjusting to ensure edges sit flush with the outside legs of the frame. Use a length of wood clamped to each leg as a straight edge for the slats.
Screw slats into place with 4 x 65mm screws per slat.
To make the upper shelf, repeat as above with the remaining 11 slats, spacing them evenly apart and screwing into place.
Seedling box STEP 6
Screw a 300mm x 45 x 45mm length of timber onto each narrow end of the frame to box it in: lower shelf, upper shelf and top of frame. Repeat on the other side. To complete the box frame, screw a 1110m length of 45 x 45mm onto each long side of the top frame. For strength and rigidity, screw an L-bracket into each corner under the top of the frame, connecting the horizontal length with each adjoining vertical leg.
Use a stanley knife to cut 2 x 170 x 270mm pieces of mesh for the sides and 2 x 360 x 270mm for the ends. Staple to the outside of the upper shelf, enclosing the box on all four sides.
To make the lid, screw 2 x 390mm and 2 x 1110mm lengths together to fit the top of the frame. Secure with 8 x 75mm screws.
Cut and attach a 1.2x. 5m piece of plastic over the outside of the lid, stapling and trimming where necessary.
Attach the handle to the front of the lid and hinges to the back.
‘Gauged’ timber is cut, then a planer is used to trim it to the right size and to give it a smooth finish.
