3 days. thats way too long. just my thought. like someone said water can go stagnant, but it would be more so after 3 days. I say if you dont know anything about your water test it.My rule of thumb is if you don't have an air stone then let the water sit for 3 days in an open container. But, by no means is that what you have to do.
Im sure an airstone doesnt hurt and they also arent expensive, but if you dont have one its not as though you need to run out and get one or your plants will die. my entire grow has been without an airstone and ive had no ph issues or alkalinity issues. no deficiencies.
