I'm sorry to rub it in to those who didn't see it but Carol Klein's
presentation on digital viewing in the Grand Pavilion, was an utter
delight.

Some of the plants were mouthwatering and mostly, it was easy to
identify
them. I
thought the Drosera from http://www.hampshire-carnivorous-plants.co.uk/
would
be very interesting to those who have problems with whitefly in
greenhouses.

Slightly OT, but the Hampshires webshop's growing conditions refer to 'a
cool greenhouse or a warm one'. Apart from the obvious, can anyone
elaborate
on the difference between cool and warm?

Bertie

Cold or cool greenhouse = unheated, likely to be cold (possibly below zero
in winter)
Warm greenhouse = one in which the temperature is prevented from falling
below freezing, allows for a greater range of plants to be kept.
Hot house = a greenhouse where the minimum temperature is maintained high
enough to keep tropical plants and bankrupt the owner.

Thanks Charlie
Keeping the greenhouse warm in Winter is going to prove too expensive. I
shall google around for a heater say, 100watts (I'm guessing) and build a
coldframe.
