should I worry much about the temp of the water I water with being to cold? I grow 12/12 from seed and I've read somewhere to use colder water during flowering , don't know if its one of those bad unproven tips that floats around but the idea was the rains colder closer to harvest , so I never worried about the water being to cold for my ladies already flowering but what about the younger ones ? Seedlings and month olders...
my cab stays fairly cool 75 lights on 65 lights off ,
water temperature is probably between 55-60 don't have a way to check it but will get a way if i should be concerned with shocking little ones
