Regarding temperatures i can say that Saturday at 9:00AM the outside ponds were at 12ºC/53ºF, 15ºC/59ºF in the ones inside the green house and 18ºC/64ºF at the ones that are now covered and heated at 22ºC/72ºF.
It's cold, but inside the green house, during the day, the water temperature it's almost the same as the last update. At night the temperature lowers to the 12ºC/53ºF.
Some plants continues flowering, interesting.
Outside the things are more more slower. The fishes come when i give food but it's hard to see them.
