I agree. I've chased my tail more with a $20 pen than its worth.and I'm in dirt!!finally gave up on it,don't need it anyhow when using organics (I'm not going to argue with anyone about this lol)If you're serious about your grow, use serious instrumentation. Otherwise you're flying blind.
BlueLab combo meter. Yes, it's expensive. It's also dependable.
<drops mic, walks away>
hahaha that's the same pen I picked up!I did finally get it to read the same (most of time)I found that dipping it in distilled then letting it dry before I retested worked but was time consuming .now I just say fuck it.I have only been growing for nearly 7 years now and the only ph pen I have ever used is the cheap and cheerful 1 that cost me £4.99 from ebay, I renew it every year or so. and I always and I mean always produce top quality smoke from it at ph 6.5 in soil. You know the saying... if it aint broke don't fix it lol. It seems to work for me, like natureboy said, I'm not gonna argue with anyone on here about it either. Got more important things to do like rolling a doobie .
My last crop and my cheap and cheerful ph pen
You know that mate haha, its done the bizz for me. I have heard of people doing that dipping it in distilled water before using, I have also had people telling me that you have to calibrate the pen especially when you first buy it. I don't even do that hahaha, thank you mr post man straight out of the wrapper and I'm using it haha. I would like to just put it out there that I am not mocking anybody what so ever who use more expensive and much better ph pens out there. I am a very fussy person when it comes down to my bud and I don't like cutting corners but my ph pen that I use produces the goods for me every time .hahaha that's the same pen I picked up!I did finally get it to read the same (most of time)I found that dipping it in distilled then letting it dry before I retested worked but was time consuming .now I just say fuck it.
edit nice look8ng plants btw!
