Litmus paper is more than accurate enough for growing cannabis.
Yes it is as are the drops. I have a meter because my eyesight isn't 100%. I rarely use it though. I don't see any need to check everytime I mix up some nutrient solution. Once you've mixed the same stuff a couple of times if you need to adjust pH it's going to be the same each time.
Local hydro store to me are stocking Apera for this exact reason and not bluelab anymore.
It happens also when like I said you need new or better calibration fluid. Your fluid may be off or old
Yeah I recommend just getting the proper bottled ph solutions for your pens. That guarantees it’s made properly and that the sensitivity is made for that pen
It’s worth emailing blue lab, in the circumstances they might replace it.
Just contact bluelab and theyll replace it. You have to send your pen to them though
Wait isn’t this the one you bought from some third party seller for like half price.
Exactly. I told him there are fakes out there.
Isn’t bluelabs warranty a year?
Shoooo fly
