Cabbage Kratky

So i finally did a full nutrient change and tub cleaning on my cabbage kratky tub. I started this up some time last spring/summer and only did one top up. Using a 26 gallon tub with 6 plants really was hands off. At one point it was completely dry so i toped it off.

So cleaning the tub was a fun time. Im not ready to reset just yet, but ill refill when i have plants ready. Im sure i could have better results if i spent more time changing nutrients, but its nice to have a system that just exists in the garage and im not worried about leaving for long periods of time.

I do get some really good, but small heads of cabbage in about 3 or so months. Heads are just the right size for individual meals. Not sure if its just the variety or the way they are growing. Im also not sure if i potentially should be providing more light to get them bigger.

Ive been starting the nutrient solution out at 2.4-3.0 ec. I have not been adjusting or checking ph as much between refills. I also add some H2O2 from time to time trying to keep the bacteria at bay.

I am trying to grow secondary heads after picking the primary, it has worked but the last ones began to rot before i could pick them. Not sure why since they are dry and low humidity.
