W8.Day.1(54)
โShe drunk about 4 liters per day before defoliation. After the stress she drinking less.
W8.Day.3(56)
โAll seems fine. No significant burns appeared on the bud with cropped leaves over several days.
W8.Day.5(58)
โGradually and carefully, to avoid causing severe stress, I remove the oldest fan leaves from the upper inflorescences. Those that are already covered in "snow," I do not touch.
โThis girl is really smart. It turns all the lower leaves towards the lower light!
W8.Day.7(60)
โThe week went pretty well. The girl is actively developing, but there are two aspects that concern me:
โโ- The tips of the leaves are slowly but surely continuing to yellow, and somewhere, claw-like formations are appearing.
โโ- There is an increase in TDS in the drainage by +200 TDS; by the end of the week, I slightly reduced the amount of fertilizers to 1000 TDS.
โThe temperature of the top buds rose to 31.5 degrees on some of the hot days. To ensure that the temperature of even the top buds does not exceed 30 degrees, I turn off one of the top 40-watt sources of blue light during the hot hours.
โDue to the new rules from GrowDiaries regarding images, I have removed all neural network-generated images. ๐

I like the craftiness ๐! I have made good experiences with Scr.o.G ing and lights under the canopy. Would only add them in flower though, I had added somewhere around 90w at 30 cm distance on a lollipopped plant. No fluff or popcorn buds anywhere to be found.
@MyDearDiary, always a pleasure, but again, itโs mostly about the individuals preferences. I just wanted to highlight to you that from my perspective there should be no issues to start carefully removing old leaves, without worrying that youโll stunt your plant. The more you grow the better youโll be able to read your plants. Seems like the curiosity is there already ;) any other questions, you can always DM me directly, if I can, Iโm always happy to help.
@Salokin, Thank you very much for this article
It seems that in a home setting, it's quite challenging to determine the photosynthetic activity of leaves and identify the moment it decreases. Making such decisions should be based on experience and the age of the plant and its individual leaves. I would be happy to conduct a series of studies.
Is there a university somewhere that studies marijuana growth? ๐
@MyDearDiary, hey growmie, I read this a while back, which was studied on sativa plants and their leaf photosynthesis rate with age
โ Compared with the maximum estimated y-intercept value, Amax and Rd decreased by 50% and 75% after approximately 9 and 28 days (Figure 1 and Figure 2). Similarly, Ls and ฯCO2 decreased by 50% and 75% after approximately 8 and 22 days. Although photosynthetic capacity declined steadily after leaf full expansion, we note that the compensatory metabolic activity of Rd decreased.โ

A wouldnโt deny that a mature leaf has a higher photosynthesis rate, however, as soon as maturity is reached the rate will go down, but also their metabolic consumption.
what is nice colour for your eyes, maybe far away from spectrum plant needs.
What ever cool leds you would use, they still heat up, that will play up with plant, because they touch each other.
output of such strip will make maybe brighter for your eye, but wont bring any countable result. through all strip its 10-15 W maybe, so what it brings ??? plus spectrum ;)))
i thought its one of photo contest attemps, but by your description - you are serious with it.
Hope it will work for you, but by pure math and facts - it should not.
All the Best !
@AsNoriu, The issue of temperature is not a concern for me, as I regularly use an infrared thermometer and make sure everything is within acceptable limits. Besides, the garland doesn't operate throughout the entire light day.
I treat this as a fun experiment.
