A conventional electric water heater will come with a black wire and a red wire which are connected to the wires of the same color as described above. The ground wire is attached to the green ground screw which is in the same wiring junction box compartment which is built into the top of the water heater.
Which option is best depends upon several factors. But moving your garden soil pH lower may be as simple as adding fertilizer or mulch. Of course, all methods of changing soil pH involve adding something to the soil. Itâs just a question of the type of soil amendment youâll be using, and in what quantity.
I've even got another soil PH tester and it still reads 7.5. I read that Gypsum is good to lower soil PH but I can not find it over here in the U.K. Is there an alternative that I can mix in / add to with the soil that will drop the PH of the soil. Can someone please help ! Many Thanks.
