In the market for some cheap PH testing equipment

I need something to test PH and raise/lower levels if necessary before I start feeding my plants nutes. I was considering this: http://htgsupply.com/viewproduct.asp?productID=52934 , but am unsure of the accuracy.

Would a small kit like that be enough to raise or lower the PH levels of a gallon of water?

Thanks in advance!

Onegow, I use a drop test kit like that and it works OK for me. Will you be able to tell the difference between 5.5 and 5.7? No. You will use an eye dropper or something like that to adjust one gallon of water. Those bottles of up and down will last a long, long time doing one gallon at a time. Good luck.

that would last u ages man .... ages .... and there not that accurate because its your eyes that have to match the colours if i know what i mean , but its accurate enuf.

search ebay you can find um for like $20 the digital kind...

Thanks guys. I just ordered those strips. I would prefer the digital one, but then I'd still need calibration solution and the drops to lower and raise ph. Cash is kind of tight.

if you're using soil:


just get the water ph tested at a local pet shop. say it's your aquarium, get some of the water you're gonna water the plants with.

your tap water will be either alkaline, acid, or neutral. if it's alkaline, you can use distilled white vinegar or lime juice to raise it's PH. if it's too acid, you can use a bit of baking soda to bring the PH down. if it's neutral, just add 2-3 drops of vinegar to a gallon of water.

peace!

p.s. if you use tap water, it's probably alkaline, so you'll only need ph down....
