Never heard of ice spraying before, but IMO i dont think it would work, as i dont know what cold water could do to a hermy to "change it". What have you heard, or read about it, im curious about it. Iv heard it will help stop the pollen from leaving the plant after it flowers, but other then that, id chop it and eat it or something. You sure dont want a bunch of seeds:thumbsup:

Good luck:rasta:
