yes sir i use rice water on my plants i have photos of her growth that i will be posting soon. the ph stays in tact and the plants seem to thrive from it. i am now in the process of doing a side by side grow to better show results, but the one plant i have been feeding stands over 2 feet tall and it is a little under 2 months old. She was sprouted on July 26, 2010 from bag seed and it is Sept. 21, 2010
