Temperature very low this week. They announce -1°c by the end of the week. No nutrient added at this time. Just clear water and sun light. Growth is very slow due to low temp.
Yea. Same situation as mine.So far this week, there has only been one sunny day, and the rest of the weather has been cloudy, and it has rained for three consecutive days, and the temperature and light have fallen to a low point, and the growth is quite slow
