Who uses artificial light???

[Anthony Darby]

I demonstrate a light meter to 3rd year pupils in our 'Biosphere' biology topic that to equal the light coming in the window on a cloudy day the meter needs to be a foot away from a single tube. Our light bank holds 4 x 4' fluorescents and can be lowered to that distance using a chain and pully.

I hope you all realise that if I take up Tony Goode's idea for putting together a lecture you are all going to have to send me pictures of these green/alpine houses, with or without lights.

All I need now is to get that *#@*~* electrician to wire up the alpine house and I can make a start!
