I’ve been around for the last 2 months perusing the forums and am on the struggle bus with my grobo. I totally understand that I am not a person with a green thumb, but I am slowly losing my patience with the grobo. I have tried to create the perfect environment for the grobo and continually get the same response from support regarding the readings of my grobo. As of today these are the things I have done to help my plant and I am still running into issues with how she is responding.
For starters I live in Arizona where humidity is pretty low. I have since purchased a cool humidifier for the backside of the grobo. This humidifier was recommended in a thread I came across for low humidity inside the grobo: TaoTronics Humidifiers 6L Cool Mist Humidifier with Humidistat LED Display 26dB Whisper Quiet Wide Opening Humidifier for Large Bedroom Black TT-AH044
My humidity has since gone from 25% to 60% since putting this outside the unit.
Additionally, I changed the air stone to an air stone circle as the stone was not putting out enough air bubbles.
My current readings are such:
Ambient Temp and Humidity are 75.5 degrees and 34%
Inside the unit near the plant are 70 degrees and 60%
The Water Temp is 68.5 degrees as well.
Our water mixture is 50/50 RO and Distilled Water
We treat the water with the start-up nutrients every water change courtesy grobo and also put in 2 tsp of hydro guard as well.
The problems we are experiencing are of 3 variety.
Browning of the roots, typically a problem of too warm of water or lacking of oxygen/air in hydroponics. I don’t know how to fix this.
The plant is growing very slow and touching the base with its leave edges. I cannot seem to get the plant to grow as fast or keep the leaves from touching, as other plants on the forum or look as healthy. It’s really upsetting me.
I have burning or browning on the edging of the leaves which is the most frustrating part because grobo support is telling me my unit is within specifications when it comes to pH levels and in general of what the sensors read.
I’ve had a plant fail, which was my first, and now I seem to be struggling to diagnose this plant. I tried feminized which was expert mode and now I am trying an auto which is supposed to be easier.
Any help would be ideal, because I really don’t want to sink anymore money into this thing. It’s turning into a money pit and is demoralizing at the moment.
Thank you kindly for your insight.
