Flushing with garden sulfur

[Jerrodg]

The PH on my soil is a little on the high side, it registers slightly over 7. I am 3 weeks into flowering, and would like to lower it to 6.5 or so. I bought garden sulfur from my greenhouse, and the guy there said to sprinkle a tablespoon or so on my 10" pots and then water. Should I flush the pots with tap water over the sulfur, or just give it a normal watering? I want to make sure that I change all the soil, as the roots are taking up the whole pot. (Which is another thread that I have started and need answers to.) Thanks all.

That could be tastie. Does it smell?

[Jerrodg]

No it doesn't smell, it was reccomended for tomatoes, so I would assume that there is no negative smell or taste associated with it. I opened the package, and they are small water soluble pellets with no smell.

[Sparrow]

Nice, have you got a meter to test the ppm of a recomended dose?

[Jerrodg]

No, I don't.

[Sparrow]

Does the bag say what the sulfer is derived from or the type of sulfer it is to the best of your memory?

[Jerrodg]

It is derived from elemental sulfur.

Thanks

An update on the sulfur. I mixed quite a few pellets in a gallon of water, let them disolve, and added them to a pot of soil with no plant in it. The soil was 7.2 before adding the solution, and has dropped to 6.0 with the solution. I may want to cut back on the amount I end up giving my real plants, but it seems to work fairly quick. I'm just scared now of dropping the PH too far.
