ifn a house is not heated during the day(people at work)the plants in cold weather suffer.
is it logical to try to have a light heating spiral underneath. or the kind to 21 degrees also what happens to hydrophonic plants they actually get the temperture of water(the same as the surrounding) how about humidity? does it have any purpose if it is cold .what does it help?i am talking about a home in jerusalem ...at night it can drop to 8 or even 3 celcius.
wich part of the plant actually suffers from the cold?
thank you
