After 10 years using soil and GH nutes, we made the switch.
Switched over entirely to Canna coco and all Canna nutes in Autopots. Since switching to Canna all the drama associated with mixing nutes and monitoring pH is over.
I’ve always checked the pH of my water right out of the tap just because it’s something I’ve always done. Gives me a mental baseline of sorts. My tap water always comes in at 7.5-8.
But since switching to Canna, after I mix my nutes, and test the pH, this is the reading I get every time.
A happy medium for me and coco is 6.0. I play the drift using auto pots and think it’s advantageous. Hits all the various nutrient uptake sweet spots. If I’m starting the initial res fill, I add about 2 gallons at 6.0, this fills the trays for starting and my res top off weekly is at 5.7-5.8 so the drift occurs through the week
When I mix my nutes I pH out at 5.7 each time.
I check the reservoir daily, and I pH out at 5.8.
A tenth of a % drift. I attribute it to the Canna nutes. They’re really stabile. It’s so nice not having to add pH up or down anymore.
I use Mega Crop in coco with auto pots. I go in reservoir at 5.6 and over a few days rises to about 6.2 to 6.3, I have tried all ro water, all tap water, and a combo of the 2 and ph drifts up. It doesn’t seem to affect the plants, although in a perfect world, it would be nice to not adjust the res every day or so.
