I have bought my Grobo Premium last month. I was very happy as i thought i would grow anything i want in my room.
When i started my Grobo I was extremely disappointed as Grobo makes extremely annoying noise! Then i have decided to upgrade the noisy items by myself!
When i open the device i found that manufacturing quality is very low! Many errors and even i found that manufacturing company was hesitated a lot to put screws into some holes. maybe he saved 1-2 cents!
anyhow i have changed air pump + fans with the silent ones and now i could have reduced the noise levels around %75. To make it %100 quite i need more space to work and need to design the device from the beginning.
Current Grobo can’t stay in your room ! you will get crazy with the annoying zzzzzzz noises!
Second thing is that we can’t check the temperature and Ph sensor levels on the App! It should be written for our reference!
You must definitely upgrade it. You should make the Grobo %100 quite!
It is %100000 possible to make it.
Hope you can take this feedback seriously.
