The plants have developed well, even the two smaller ones that had a somewhat slower start. Almost all the plants have topped, one now for the second time.
My aim is to tip and stretch the 9 plants so that the space is optimally utilized and the light yield and ventilation are optimal. I also want to get all the plants to approximately the same high level.
Edit:
@SecretTreasures, OK! thx m8! Iam at 2 weeks in flower. I always had the lamp in veg , and to the start of flower at 75% , and 60 cm.
What do you think about that iam gonna turn it up to 100% and make 65cm above the plant? i got like 850-930 PFFD , and a little over 50 k Lux, and 53-57 DLI :D. .... well well well :D
@Polodk, Yes exactly, I use the Zeus 600w 2.9 pro.
So I only have the supplied controller, which works with setting options of 0/25/50/100%.
In general, I tried to hit the recommended ppfd values for the corresponding phases and roughly moved around the recommended distance of around 50cm. I used the 'Photone App' to get a rough estimate of the ppfd value at which I was moving, although this is of course rather inaccurate.
In the seedling stage I started with 25% at a lamp height of about one metre, maybe a little more. As soon as the seedling stage was complete, I lowered the lamp to a distance of about 50cm. Then I let the plants grow a little closer to the lamp and a few days after topping, I think about 5 weeks after germination, I turned it up to 50% and adjusted the height. Then I always kept a distance of around 50cm (+/-10cm) and checked with the app from time to time.
As I defoliated once at the start of flowering, I waited another two or three days and then set it to 75%.
At the end of the 4th week of flowering, I raised the lamp to its maximum height and set it to 100%.
As the 600w already has plenty of power for a 120 cm box, I would just make sure that the lamp has enough distance at 100%; during the growth phase, it can sometimes be closer. Just keep an eye out for signs of light stress. You should also wait a few days after stressful situations, such as defoliation or lollipopping, before rising the power, to allow the plant to regenerate so that it can better adapt to the new light conditions. I hope I was able to help you a little, if you have any further questions please contact 👋🏻
