Slight mistake with feed but I think everything should be ok.
My main issue at the moment is trying to keep the DWC solution at 18c. I have started to freeze bottles of water. In the hope that adding a sealed frozen ice cube can help reduce the temp.
Day 9 I made thermal coat which allowed me to put the ice packs in between the bucket and the jacket. Which worked perfectly, bringing the solution temp down to 18/19c without touching the roots.
The roots are already taking hold. 4/5 main roots are 3+inches long and looking very healthy
Highly recommend Hydroguard, allows me to grow DWC in the desert with high water temps. Also should help with that brown root rot that's starting to show on your roots in pic 4. GL growmie!
@LuckSackGrows, Hydroguard isn't in stock anywhere in my country at the moment. Super annoying but making look at alternative solutions.
Like solution temp, more air, and I have now changed the solution and tweaked it by adding Advanced Nutrients tarantula. Which has the same microbes as Hydroguard.
So far everything root wise is looking ok now
