自制肥水的pH酸鹼值

以下是我自制的一些肥水, 已經經過幾個月至一年以上時間發酵, pH酸鹼值如下:
米水: pH=3.9
環保垃圾酵素: pH=8.5 (我以為會是酸的)
蕉皮水: pH=5.9
海帶水: pH=6.3
奶水: pH=6.7 (少奶)
花生麩水: pH=  (太臭啦...未Check)
廚餘水:pH=7.5   (菜葉, 蝦殼, 蛋殼,果皮, 植物, 魚骨及腸臟....)
自來水: pH=8.0
山水: pH=6.2  (麥理浩徑10段(屯門) 02 Jan 2012)

"Heinz" Vinegar 5% acidity 醋 pH=2.2  (不知能否用於水培液, 降低pH!!!???)

請問米水浸左幾耐 ?

冇諗到竟然去到 3.9 咁酸

放咗幾個月; 試過有一次浸咗幾個星期, 連玻璃瓶都爆埋...味道似Yogurt.

小時候聽過大人叫它做 臭屁醋

You use pH meter to measure those data?

interesting and very scientific

是的.......

pH 4.000 and pH 7.000 calibration solution, ... well I have the solution, but did not calibrate it, because I have two pH meter and they both read about the same reading, so, trust them..

嘩！咁勁‥‥‥‥兩部pH meters.

養魚用架

養魚要用幾多pH架, pH meter 要成仟一部架。

唔記得啦....
pH meters were bought 7 years ago, was $700 and $250.

有無測過水喉水ph幾多，我買咗ph試紙測倒大槪5.8-6.0; 但參考水務處資料以為會係around 8?

pH metre sold in Philip Harris can be very cheap and robust design
http://www.philipharris.co.uk/se ... -1-hanna/?ev=search  only GBP 29.95

that is around 500 HK dollar, u can approach the local laboratory supplier and quote the reference number, let them quote the price for u

this lab supplier got Hanna product

今日買了五兩海帶,2.00/兩,用了一半,浸了三小時,換了兩次水,洗去鹽份,切碎,然後放入瓶,加了4L水,封囗,...做鉀肥

sigh...上網番查佷多資料,我相信就咁浸海帶做鉀肥糸吾得,要有酵素降解先可以,做鉀肥最好的方法是草木灰,明天將浸左的海帶倒入堆肥桶...

堆肥桶就有酵素了@_@

Thanks magichand, 咁如果我測到~6，係咪即係試紙唔準？定有可能幢幢大廈水ph唔同？
