  • 1. Making a windowsill light reflector Since light only comes from one direction on a windowsill, plants tend to stretch towards the light, especially seedlings. To prevent this, make a simple cardboard reflector covered in shiny aluminium foil to evenly reflect light so seedlings grow straight.

Take a cardboard box and cut off the top so it is around 15-20cm tall (this height suits trays of seedlings). Alternatively, fold a cardboard sheet in half to create an ‘L’ shape and tape separate diagonal supports to hold cardboard in place. 3 4 3. On the front side of the box, measure 3-4cm up from the base and draw a straight line across. 5 4. Draw a diagonal line from the top of the new front edge to the top corner at the back of the box. 5. Carefully cut along these lines. 6 6. Line the base and sides of the box with plastic and use sticky tape or glue to secure. 7. Line the base and sides of the box with aluminium foil, shiny side showing, again using sticky tape or glue to secure. 7 8. Place your finished light reflector on a windowsill and start growing! 8 2/2
