I just recently run into this type of problem with not enough aerated water. I recently moved up from a 24 oz. cup grow to using 1 gallon containers. It takes more water to have the runoff I like to see. I only have a 5 gallon bucket to prepare the water. I also use this water to mix up nutes.
My solution? I have started just using water straight from my sink. Right into the 1 gallon jugs and then right into my plants. I have always heard that this is the wrong thing to do. That is... using chlorinated water from the sink. So far no problmes and I have been doing it since I put my current plants in the flower room.. 26 days now.
Something like: **Tap water PH's around 8.0 and I don't PH down**
1. Water (chlorinated tap water) with runoff and then 1/2 strength nutes. (2 to 3 days to dry out)
2. water (chlorinated tap water) and let dry out (2 to 3 days to dry out)
3. water (chlorinated tap water) with runoff, check PH and then 1/2 strength nutes. (2 to 3 days to dry out) **Sometimes I skip nutes here if I get a nut burn.
Rinse and repeat.
So, I was thinking if you had a hose you could just water from the hose outside. I saw my neighbor who has a bazillion flowers and she was watering straight from her hose. I thought damn! Cannabis is a weed? It should be fine with chlorinated tap water. *I effectively assured myself it was ok*
whew... I need a break.
