Batch#01 - 15 Jan - Day 37 (Batch redefinition)

Redefining the concept of Batch

I started off by using the term "Batch" to refer to the first batch of seeds, sowed on Dec 09 2020. Over the course of 35+ days, I am convinced that the water and nutrient solution remains relatively rich of the requisite nutrients, and clean, in the sense that there are no signs of algae. Roots of plants remains crisp to the touch, not slimy or rotting.

With this positive solution in place, I thought to experiment with a continuous planting until such time that the water and nutrient mix needs to be flushed out and replaced, and the setup cleaned thoroughly. 

So the term Batch 01 now refers to the first batch of water and nutrient mix.  

Interestingly the EC has increased overnight, while pH remains below 5.5. The lettuces looks pretty much the same, healthy and slightly taller or larger. It would seem that the lettuces are reaching their limits.

Lollas are growing well.

Data

EC1600

- a surprising increase, thought I am not too sure why.

pH5.41

- remained below 5.5. Hopefully, the pH edges into the desirable range.

WT28

Water level: below mid level.
