Part 1 (Beginning of week 7): The last few days in the 23l pots have been very good for the plants. They have grown up to 4-5cm a day and have recovered amazing from my fail with the humidifier. I have slowly turned up the 320W lamp from 5-10% to about 20%, my temperature is between 24 and 28 degrees while the humidity is somewhere between 45% and 55%. Next time I water, I will give a little more than 500ml per pot. Fertilizer is set out for about one more week after the plagron all mix has been well pre-fertilized.
I'm also planning to switch to 12/12 tomorrow (beginning of week 7) and before that I used LST on two of them. I used simple wire from the DIY store and lightly "pre-massaged" the stems of the two plants I wanted to tie down so that they wouldn't break off. at first I tried to wrap the wire around the stem, which didn't work out so well, so I just made a small gate which worked really well.
I then moved the two tied-down plants and pot a little closer to the light and to the same height as the others. and now I'm really excited to see how the difference will be noticeable (and whether I'll have any space problems) :D
Part 2 (Endof week 7):
As I switched lights to 12/12 the progress is just amazing. The stretch looks healthy, the leaves have turned a juicy green and the plants have grown a strong stem and beautiful side shoots.
At the beginning of the week I was struggling a bit with the temperature, probably because my growbox is located in a very small room which heats up quite a lot. I realigned the fans and adjusted the openings on the sides, which helped a bit. What helped the most, however, was hanging the exhaust hose as far out of the window as possible and leaving the window open 24/7. This allowed me to keep the temperature below 30 degrees.
Even if I'm not quite sure what I'm doing, the plants take the LST well. One of them has developed two beautiful shoots which I have tied down.
Besides that... I am having so much fun watching the daily progress and I am excited to see what week 8 will bring.
Cheers
@AutoflowersSucK, Because of the hanging leaves?
In the first 4 pictures they were very stressed from the DHL trip and from my humidifier fail. I took the last pictures today just before watering. I've generally made sure to give them enough water, but not too much.
