THE BIG QUESTION
What in the world you do if you tested the DO in your rez water and discovered that your DO is way too low, not safe and everything in your rez water was suffocating?
Would you punt, hope and pray, make teas or fix the low DO problem and urgently increase your DO up to a safe range? And who in the world really knows what the safe DO range is anyway?
Some growers claim that rez water temp is very important – you got to buy a thermometer and test the water temp.
Others claim the rez water pH is really important too, you got to buy a pH meter and use it.
There’s a big crowd that claim you got to buy a water chiller, got to keep the rez water temp 65F to 70F, you got to buy a water chiller and use it throughout months of the growing season.
And if you do that, well that cold chilled water will insure plenty dissolved oxygen in your rez water because the DO chart proves it. And maintaining minimal safe DO is very important for the root balls, the Bennies to thrive and to prevent fungal infestations that come to eat dead and dying roots.
MORE QUESTIONS
So, cutting to the chase now, do you really believe that insuring minimal safe DO is really all that important in rez your water for the root balls and Bennies to thrive and to prevent them from suffocating?
If minimal safe DO is really that big of a deal for aerobic plants and microbes in DWC pot grows, do any of you ever actually test the DO in your rez water?
What do you use to test the DO with? And how often do you test the DO in a DWC pot grow?
