You can often google your city's ppm. This leaves a lot of unknowns out there, main reason I went back to DWC. Over watering, CalMag and transplant issues. Thanks for the help though.
No need to transplant whatever you’re growing in mate. Germ and plant in final pot. Done. Can’t see the point of transplanting autos.
Unknowns aren’t really such a problem. For me it’s about learning the plants so I can read them, rather than a meter. Stuff happens quick in coco so easier to see an issue starting and deal with it.
My last grow was photo-period only. Transplanted very healthy plants in coco to Autopots in coco. GH coco bricks claim theres no need for extra CalMag(bullshit) and they fuking drowned in overwatering too. Been growing DWC for so many years that any soil type of medium seems like a huge headache. Thats why I want to try the Biotabs. I am growing a perpetual grow now. Harvesting one auto every 2-3 weeks to stay legal under Nevadas bullshit 2.5 ounce medical possession limit. Otherwise I'd be growing trees.
Your tap water will work,
Biotabs uses Micro organisms and Bacteria, that will lower the PH or EC by it self. Nature will make sure the right levels are available in the soil.
But is is beter to use RO water, although there is going to be missing Cal/Mag. So if you add the Silicium flash to the soil, that issue will be sorted aswel.
I use the Growmax Power grow.
I like that filer due to its efficiency, 1 liter of clean water, 1 liter of dirty water thown out.
Biotabs will tell you tap water s good but RO is better I think. I believe they use RO themselves. I use biotabs and autopots and live in a hard water area, and I just fill the res and get on with it. No issues so far, but this is my first run with autopots.
