Idiots guide to grow lights

I look on blue Peter crafting as the highlight! I have the box and the foil, now need to find the inclination. I still smile at the colour of the lights emanating from my study (the spare room). There are various ribald comments from P as you can imagine.
Actually today is an exciting day (all things relative) will be gaffer's mate when P replaces nextdoor's outside light for them this afternoon.
