I am testing rockwool PH with runoff + a syringe, since I killed my first batch of beans I want to get it right on this second $80 batch of beans. Yes I have free seeds I could use but I am stubborn and this shouldnt be hard to germinate.
Anyways the runoff comes out at 6.5+ ( just under 7 ), watering with 5.4 tap. If I soak the cube or water it enough ( ounces of water ) I get the runoff down to 5.7 range.
Now heres a neat trick for drying out the cube after soaking it. sit it ontop of a towel. Wait 60 seconds, half the water will be gone, after 3 minutes the cube will almost be dry, gravity causes the towel to wick all the water down.
SO anyways after I dry the cube I water again and runoff comes back out at 6.4 - 6.5.
Now I did some research and read some hydro books on google books and I am under the impression the 5.6-6.4 PH is only to offset the high PH of the medium, am I under the impression your medium should be 7.0 nuetral? Because these damn cubes seem to want to stay right there.
