Using a ph meter

[weedman420]

How do i use a digital ph meter i just bought one but have no clue what to do now.

[jackel]

u turn it on and put it in ur water and it tells u what ur ph is LOL

[weedman420]

it says something about calibrating?? and to adjust it with a flat screwdriver at 7.01. Do i need to buy that 7.0 solution?

[jackel]

oh, yea u will have to get the solution and calibrate it. fill a shot glass with the solution. theres a 4.0 solution too.

Do i put the ph in the water i use now to water? I did and it said 8.79? Im assuming that i have to go buy the solution? Do i need the 4.0 one too if so why

[jackel]

yea, u need to calibrate it to the 4.0 and the 7.1 also dont forget to put it in plain water between going back n forth to wash off solution. this sets the high and low of ur pen. if you live near a grow shop, u can take it to them and they can calibrate it for u also. once calibrated, it stays good for a while as long as the glass diode doesnt dry out
yes u will want to check the water u are going to water ur plants with. soil isnt as picky as hydro is with ph
