*ADVISE NEEDED* The day before yesterday I discovered a huge error in my system. I placed filter material in the feed-throughs of the breeding boxes. This is to prevent the roots from growing together over time. However, what I caused with that is very difficult to explain. The bottom line is that the distribution of food and circulation was actually not good at all. This also explained the differences in the water temperature, but also PH and EC values. That is now completely under control because it now runs stably for 2 days. However, you can see that the records have had a bad start. I am thinking about starting over. Week 3. Week 2 was looking for the correct settings for my system. I found out that the temperature in the bins is quite different. When I set the water chiller to 19 degrees, it all flows fine into the first container. There it rises about 0.5 degrees per bin. The margin of the chiller is about 1 degrees, causing too many fluctuations in the system, with tray 1 becoming too cold and the last one too cold. I solved this by shielding the box at the inlet of the tent with heat-protective foil. I also put a fan on the water chiller. If that catches on, the entire loft heats up, whith more fluctiations. However, I have enough space to measure very precisely and I am getting more and more control. I think the brown leaves were the cause of much too hot water. Since I have the water temperature under control, I see that the new leaves are growing nicely. Moreover, since yesterday (13-5) I received the nutrition. 10 days late. I just finish the root scheme I think. That is still 3 days a 70 mm per day combined with BioBizz Heaven. I tried to take some pictures of the roots and some close ups. I hold the lid with my left hand and with my right hand I try to take a picture zoomed in (max). While the wind makes the roots dance past my lens😵 Something different than usual ... Hope you like it. If you see something that needs to be addressed, let us know. It is my first breeding so there will undoubtedly go wrong. This week I also connected the water reservoir with which I can flush the entire system at once. With this I also control the Ph in the system. Will post photos soon.
