When a clear snot forms on roots in a DWC, and the normal course of treatment for root disease doesn't work, you probably have something called brown slime algae, which actually isn't algae at all, but a cyanobacteria. It loves oxygen and doesn't need light to grow. It doesn't care if your res is chilled or not. Safe levels of H202 slows it a bit but doesn't cure it. It can show up for DWC growers for no apparent reason even after years of successful grows. Once it shows up it's often a nightmare
PH Electrode Care and MaintenanceYour pH electrode is the most sensitive component of your pH instrument. Correct calibration procedures combined with proper maintenance will provide years of reliable measurement. Calibration Since glass pH electrodes measure H+ (hydrogen ion) concentration relative to their reference
I usually get an email from time to time from someone who is experiencing wild pH swings in their hydroponic reservoirs. Growers usually tell me that their pH was around 6.2 one day and then 8.0 by the next morning or some similar story. This situation becomes a little bit frustrating as the grower does a huge effort to keep the solution at a certain pH level
Over the years I have collected some interesting info on growing and thought this is a good spot to share it, so I will post it all here, something different every week. If you have some good info feel free to post. Peace and good growing to you all.
Here is the first one on Bud Rot
Here is some info on Botrytis, I use an Ozone generator and follow the steps below and have not had any
