Yep, i should of said that... whatever container you have it in should not be sealed, otherwise as the chlorine evaporates the gas will not be able to escape the container, effectively stopping its evaporation until you open the container and it can 'breath'

if you need faster results you can also boil the water... make sure its not boiling hot when you give it to the plants though! you can also just leave it sitting in the sun for awhile... basically the warmer the water is, the faster the chlorine will evaporate... of course, the water will evaporate faster as well, but not nearly at the same rate as the water..if you go this route, just make sure you boil a larger amount of water than you actually need, because you will lose some of it... IMO, boiling is just a waste of energy though... just plan ahead and let it sit on the counter for a couple days... boiling it might also remove some other harmful products from the water too... but it will also kill any micro-organisms that may be living in the water, some of which may be beneficial... but i am neither a biologist or a chemist, so...

the other option is buying dechlorination drops/tablets to add to the water that will remove it... you can generally get these from any pet store that have aquarium supplies
