Hi All,

Hoping a fellow farmer can help me out. I built a simple bubbler clone bucket but have noticed rising PH with Ro water - I also tried a mix with tap and still got a similar rise. It goes from 6.0 to 7.0 in a matter of hours.:worried

Is this normal? Do I need to keep adjusting the PH or can I let it run?

Simple set up

20ltr bucket
7 net pots in lid with neoprene sleeves.
1 submersible air pump.
1 external air pump feeding porporus pipe.

any help, comments would be appreciated - am due to drop my clones in it tonight!

thanks all,

Normal when CO2 is driven out and water column is saturated well with O2, so that alone can cause a good bit of shift. The more alkaline the water, the greater the tendency to land at a certain pH range, so I would stick with RO water and then adjust it down, allowing for a bit of bounce. Bubble the water first, as it appears you're doing (very good idea! too many people just jump in), then adjust.
