[QUOTE="John Slejpner, post: 6930990, member: 819"] Not sure at all but i suspect no. The water thing on a frost / pre frost is all about Entropy, Heat of Fusion and so on. When ice thaws 334 joules of energy needs to be adsorbed per 1 gram of ice...this energy is taken from the immediate surroundings including the leaf the ice is on. In a marginal frost on a delicate leaf this heat of fusion energy draw is enough to damage a leaf that might otherwise be ok...that is why irrigating warmer water, usually ahead of sunrise, sometimes works very effectively.
