Hey guys, I was just wondering, what is the best way to check PH and PPM using a waterfarm or power grower? The top container is a bit heavy filled with hydroton and it seems like a bad idea once the roots reach the water in the res. How do you guys do it? Is it safe to lift it while the roots are hanging down? Also, doesnt light harm the roots? Or does it not matter if its just for a short period amount of time. Thanks!
