H2O questions

Can anyone tell me if water temperature should be a concern? Also I know that overwatering is a common problem, how often is too often and how much is too much? I've been giving my babies 150ml once the soil gets dry which seems to be about every 3 days. Right now they are in 16oz plastic cups with a couple of little holes, 150ml saturates the soil pretty well and there is a little run off. Also I've heard that spraying the girls with tonic water will give them CO2 is there any truth to this? And if so how often should I do it.

Never spray your plants with carbonated water. You will leach nutrients from the leaves. This is called 'reverse foliar feeding'.

Water should be comfortable for you to put your hand in- cool and refreshing, not cold, and definitely not hot.

Don't worry about CO2 unless you are running all other variables at optimum... this comes later.

Thanks I kinda guessed that room temp was the best way to go. I was going to use this filtered water out of my fridge but instead I just used tap which is probably better for the plants anyway. I checked the ph and it was gtg

You can use the filtered water.Just let is stand,and become room temp.The tap water has chlorine in it.If you not using a well.So let it stand for 24 hours,the chlorine will evaporate.
