W3.Day.1(19)
Painfully and carelessly, but Jessica managed and feels good. I immediately prepared the second level so as not to damage the grown foliage later.
W3.Day.2(20)
Today, I fully assembled the lattice, which will serve as the foundation for further LST (Low-Stress Training) and the placement of LED strips for lighting from the inside.
W3.Day.6(24)
Merry Christmas, Jessica, you've grown a year older. Just kidding!
I've assembled the targeted lighting option. At a surface temperature of around 32-33 degrees, these strips provide nearly 3000 lux at a distance of up to 3 centimeters. This is needed for indoor illumination, where light usually doesn't reach without defoliation.
I hope that the airflow will be sufficient for effective cooling. In any case, it's fun!
I used drying and hardening clay to shield Jessica from the hot resistors, which were eager to show that they could reach 45 degrees. According to my assumptions, after the material dries, its thermal conductivity will decrease, and the heat will be dissipated along the entire length. In any case, I will be adding additional fans to cool down the tree.
W3.Day.7(25)
I checked the condition of the leaves - burns remained only on the two from yesterday. No new burns were detected. I'll continue to isolate the resistors with clay. I will do this gradually.
I also secured the bent edges of the pot to the drainage to reduce the amount of light hitting the pot's walls.
The thing is, in the last grow, the roots grew quite well through the pot and felt pretty good until I started lighting the bush from below and killed those roots with light. This time, I will give them both air and darkness.
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.
