Kalini Asia, First grow, 0,36m², Mars Hydro TS 1000, Autopot Easy2Grow 8,5l

Starting week 1 on 18.12.23 with ca. 5 cm high seedlings. In the following days I noticed very fast growing and thin tribes. My assumption is, that this happend to high temperatures during a failure of the control system (~30°C) or/and to high distance to the lamp (ca. 30 cm). I reacted with lowering the lamp and got the temperature under reliable control, which sucessfully stopped the growing in height.

After a good start in week 1 I started to experiment a lot with my grow setup. Due to my impatience I removed the lid of my cultivation box. After a few days I noticed a relative slow growth compared to the first week. My assumption is, that the relative humidity was to low (30-40%). I didn't want to put back the lid of the cultivation box (don't know why ... Im dumb :)). So I tried to bring back high relative humidity with alternative ways (wet towel, lower temperature, on/off switching of ventilation). Nothing worked really well so I finally decided on day 16 to put back the lid of the cultivation box. Simultaneously I raised the temperature (Day 25°C, Night 20°C) and raised also the PPFD from 300 to 600. P.S. Sorry for the bad quality of photos. My smartphone has broken and I had to switch transitionally to an older smartphone which has unfortnunateley camera issues. Waiting anxiously for my new smartphone.

First days of this week were mainly about tuning my grow setup for the new targetvalues for temperature (Day 25°C, Night 20°C), humidity (60%) and light (600 PPFD). I think the plants had a good response to the changes. They look healthier as before. I saw roots at the bottom of the cultivation pots so it's time to transplant into bigger and final 8,5l Autopot's. Day 20: Transplantation to Autopot's Holy....This was a stressfull. I washed the cultivation soil off the plants and tried my very best to not make anything wrong. We'll see if the plants will recover from this. Made a big mistake and forgot the root control disc of the Autopots, which prevents roots to grow out of the pot and in the tray. When I noticed, that I forgot the RCD's the plants were already transplanted. I thought it is to hard for the plants to be transplanted again out of the hydro medium (Coco and clay pebbles 60/40 btw). So I made the decission to not transplant them again and just put the disc between the pot sock and the pot. I hope this will also be fine. When root are really conquering the tray I will simply cut them I guess. In addition to the transplantation I cleaned up my growbox and changed the multiple plug against a bigger one. Now I have 3 free plugs, which I may need for other electric devices. One of them will be an ESP32-CAM, which will make photos every hour. No photos from my new setup yet, but I will make some in the next days.

_____________________ Day 21: -------- Today, as promised, I'm showing you the first pictures of my two transplanted plants in my new growbox setup. Plant No.3 didn't get a place in the new setup and is now standing in the house to be admired :). Fortunately, my new smartphone arrived today and I was able to take some very nice photos of my ladies. On picture 3 you can see the recovery of Plant No.1 on day 21. I think they both survived the transplantation well. Picture 5 is a special addition from me this week. You can see a complete description of my setup. If you have any questions, I will of course be happy to answer them. I would also be very grateful for any helpful hints. ________________ Day 22: Plants have still hanging leaves, but I think they are stable and still curing from the transplantation. I try to disturb as little as possible and keep conditions stable. Unfortunately temperatures are below 0° C so I will take less photos to avoid large temperature deviations in the growbox. _________________ Day 23: On the second day after transplanting, it becomes clear that the plants are not doing well. In my opinion, the signs point to too much fertilizer. I followed the instructions on the fertilizers, but it seems to have been a bit too much for the little ones. I added 0.5 liters of pure rainwater from above near the plant. _________________ Day 25: Watering with pure rainwater has helped. The yellowing of the leaves has slowed down considerably. Nevertheless, yellow tips still appear here and there. I watered again with 0.5 liters of pure rainwater and this time measured the EC value of the drain. This was 1.5 ms/cm, as it should be according to the fertilization scheme. However, the value is 1.5 after the second flushing, which indicates an overdosage before flushing. I think that flushing is enough for now. I will continue to monitor the plants very closely. ________________ Day 26, 27: Little adjustments of ventilator and temperature control.
