Planted about 1 month ago in Aerogarden Farm. The tank is about 10L (2.5 gallons).
I use Advanced Nutrients Sensi system which is quite good at keeping pH levels in check. I also use Cannazym (converts dead roots into food) and Hydroguard.
BUT… we had some very warm weather here and the tank must have gotten too hot. The leaves on one plant started to droop. Checked it and lo and behold the roots were looking gnarly… Don’t know if this was the right thing to do but I did the following:
Completely emptied tank and cleaned it with bleach
Trashed the dead one (pic below) with it in my hand
Stuck other two infected plant roots into a cup with hydrogen peroxide for 10 minutes. Rinsed w water
Cut bottom part of dead roots off… You’ll see the healthy plants and the infected ones (the one with two roots vs the one with the roots and bottle of water next to it)
I’ve never seen bubbles either… I guess I’d have to use an external fish tank pump (I have one but never bothered to connect it).
I already use Hydroguard and keep temps under 70F… I also added Mycorr (good bacteria) and Cannazym…
Is that enough to keep the roots healthy at this point?
Amazing how a few days in the 90s can completely ruin your tank if you aren’t careful!!!
Everything you used sounds good but it is extremely important to have an air pump with an air stone in tank.
A rolling boil look to the surface is best for air bubbles. Oxygen is also needed in water for the plant to survive a healthy growth cycle.
Low oxygen and hot water temps are perfect conditions for root rot. Always keep an eye on roots. The rot starts as browning but once its slimy you for sure have a problem with the system.
I used to use cannazym but now I use sensizym for the same purpose with better results. Use what you have is fine. I mention that as a future option for you.
I also run a crazy system so it’s a bit different than your aero garden which is primarily made for growing herbs. As you progress in growing I’m sure you will upgrade but everything you have happen that seems so bad is actually the best way to learn and become a pro grower. So keep up the great work and never give up !!
