Had to modify the Tiny Tim tomato's water reservoir as it required constant refilling.

Gave up the #Kratky in small container ide because it is really hard to handle it for water thirsty plant like tomato, even if it is a midget cherry #tomato, it still requires about a liter of water every other day or so.

Replaced the small 1L container (half the 2L milk ;title in France) with a 5L water bottle from Casino/Leade Price.

Bought a bottle for 1 euro to make sure I have a clean water to feed it for the coming days.

Added 2,4g 4-18-38 #(masterblend) nutrients plus 1g of #Calcium and 1g of #EpsomSalt (magnesium sulfate).

The bottle is not painted right now but I will paint it black and cover it with Aluminum foil later. And I only kept 4L of the water as I cut the top of the bottle to fit the already stable plant in the upper top of the 2L milk bottle to prevent any stress to the already shaky plabt. (Already had 5 delicious tomatoes from it).

To make sure to get the best results, added a small USB airpump with a small aurstobe to turn the system into a DWS instead. The USB will be connected to a solar panel charging a salvaged 18650 LiOn battery from an old laptop, connected to a ESP32 that I use for controlling 3 different #USB airpumps in different containers (via a step up converter to turn 3.7V of the battery to 7V that is the middle of the range of the USB pumps.

I will post about the connection and the program for esp32 code later. I may add low water level warning indicator or even a #Bluetooth or some kind of messaging via #WiFi later but for now I am trying to refresh my rusty coding mind to keep adding new functions to the #esp32 unit.
