No flush needed with organic medium 🤟 ---

Apera. The one that does like 4 different things I guess. I told the guy right now I’m just trying to learn ph. Lol got me for $140. It was worth it though. The thing is on point and haven’t had to calibrate it once. ![IMG_1416](https://global.discourse-cdn.com/growingmarijuana/original/4X/e/6/7/e6714d502297c36336e83fce1cd0f18ac2bdcfa4.jpeg) ---

Just an FYI: probe needs to be stored in storage solution or 4.01 PH calibration solution. If you let the glass bulb dry out it will crack and no longer function. ---

@Myfriendis410 Yeah I was told that if I’m using it weekly the moisture from the clean water I use between dips would be sufficient enough. If I take a break and don’t use it for a month or more is when I should use the storage solution…… Is that not correct? ---

I would follow the instructions in the manual, it’s a tool and a pretty expensive investment and if it acts up could cost you even more plus replacing it. Not a risk I would take. ---

There is no need to flush with organics like mentioned by some great growers, have you tested your water ppm you are using? Seems to me it’s hard water? ---

@Autos-only Yeah it says that in the manual as well. ---

@Autos-only I use nestle pure life, reverse osmosis. I haven’t done any research on hard water or testing for ppm. I’m on my first grow and I will be researching a lot as now new quaestions and variables like ppm that have come up as I pushed through the first one. ---

> [@DevanGuy56288](#): > > Is that not correct I would fill the cup with storage solution and when you’re done just put the cup back on the unit. I fill mine only when the liquid level gets low. I would not let it dry out at all. They also indicate that use of distilled or R/O water for storage is a no-no. Has to be storage or 4.01 PH cal solution. ---

Yeah I’m just following the manuals instructions so I don’t know. 🤷‍♂️ [Previous page](https://ilgmforum.com/t/soil-ph-can-you-lower-when-alkaline/102056.md?page=1)
