With the last heat wave, I had an answer to one of my questions, clearly my chiller is not doing the trick.
I have water temperatures that went up to 27ยฐ, which is way too much, the plants deprived of oxygen, started to declare several deficiencies due to an assimilation slowed by the lack of oxygen.
It is then that a nasty fungus came to say bijour, it is me MR pythium!
It was necessary to act, at the risk of having to restart the culture.
So I applied hydrogen peroxide and ROOT ROT X, and both products are doing harm to this nasty pythium, things are now back to normal.
On the other hand, the plants had a decreased growth for 10 to 15 days, so I'm going to extend my growth for 10 to 20 days, that is to say 1 or 2 soups, I'll choose according to the root development of the plants. Before going to flowering, I have to catch up this delay in order to make a nice crop.
