Hi... I have one aspect of my plans That I am not entirely comfortable about and it is the Ceramic heat bulbs ....Will they create enough heat to penetrate the soil and what precautions can I take to ensure there is no risk of damage from the heat to the freezer .....I have used these bulbs and they are really hot when one touches them but I do not consider the heat they emit is dangerous .....of course I will ensure the bulb sockets are positioned safely..

I am hoping that by putting the thermostat probe in the soil in one of the stainless steel pots the bulbs will be controled to provide a constant exact soil temperature???
My pots being washing machine drums have "air holes" round them which should help the soil temperature..and they have been cleaned since photographs were taken..And I will buy Trays that each can sit on to keep water ending up in the freezer .... Regards Ron
