Lacewings seemed to have mostly killed themselves by flying into hot lights fixtures. Done very little to combat if anything.
Made a concoction of ethanol 70% , equal parts water and cayenne pepper with a couple squirts of dish soap.
Took around an hour of good scrubbing the entire canopy.
Worked 4-5x more effectively and way cheaper.
Scorched earth right now, but it seems to have wiped them out.
If I attached a plant to two separate pots but it was connected by rootzone ,one has a pH of 7.5 ish the other has 4.5. Would the Intelligence of the plant able to dictate each pot separately to uptake the nutrients best suited to pH or would it still try to draw nitrogen from a pot with a pH where nitrogen struggles to uptake?
Food for stoner thought experiments.
What happens when a plant gets too much light?
Well, it burns and curls up leaves.
That's the heat radiation, let's remove excess heat, now what?
I've always read it's just bad, or not good, but when I look for an explanation on a deeper level it's just bad and you shouldn't do it.
So I did.
How much can a cannabis plant absorb, 40 moles in a day, ok I'll give it 60 moles. 80 nothing bad ever happened.
Reactive oxygen species (ROS) are molecules capable of independent existence, containing at least one oxygen atom and one or more unpaired electrons.
"Sunlight is the essential source of energy for most photosynthetic organisms, yet sunlight in excess of the organismβs photosynthetic capacity can generate reactive oxygen species (ROS) that lead to cellular damage. To avoid damage, plants respond to high light (HL) by activating photophysical pathways that safely convert excess energy to heat, which is known as nonphotochemical quenching (NPQ) (Rochaix, 2014). While NPQ allows for healthy growth, it also limits the overall photosynthetic efficiency under many conditions. If NPQ were optimized for biomass, yields would improve dramatically, potentially by up to 30% (Kromdijk et al., 2016; Zhu et al., 2010). However, critical information to guide optimization is still lacking, including the molecular origin of NPQ and the mechanism of regulation."
What I found most interesting was research pointing out that pH is linked to this defense mechanism. The organism can better facilitate "quenching" when oversaturated with light in a low pH.
If I can prevent reactive oxygen species from causing the damage of "too much light".
The extra water needed to keep this level of burn cooled though,
Reactive oxygen species (ROS) are key signaling molecules that enable cells to rapidly respond to different stimuli. In plants, ROS play a crucial role in abiotic and biotic stress sensing, integration of different environmental signals and activation of stress-response networks, thus contributing to the establishment of defence mechanisms and plant resilience. Recent advances in the study of ROS signalling in plants include the identification of ROS receptors and key regulatory hubs that connect ROS signalling with other important stress-response signal transduction pathways and hormones, as well as new roles for ROS in organelle-to-organelle and cell-to-cell signalling. Our understanding of how ROS are regulated in cells by balancing production, scavenging and transport has also increased. In this Review, we discuss these promising developments and how they might be used to increase plant resilience to environmental stress.
Temperature stress is one of the major abiotic stresses that adversely affect agricultural productivity worldwide. Temperatures beyond a plant's physiological optimum can trigger significant physiological and biochemical perturbations, reducing plant growth and tolerance to stress. Improving a plant's tolerance to these temperature fluctuations requires a deep understanding of its responses to environmental change. To adapt to temperature fluctuations, plants tailor their acclimatory signal transduction events, specifically, cellular redox state, that are governed by plant hormones, reactive oxygen species (ROS) regulatory systems, and other molecular components. The role of ROS in plants as important signaling molecules during stress acclimation has recently been established. Here, hormone-triggered ROS produced by NADPH oxidases, feedback regulation, and integrated signaling events during temperature stress activate stress-response pathways and induce acclimation or defense mechanisms. At the other extreme, excess ROS accumulation, following temperature-induced oxidative stress, can have negative consequences on plant growth and stress acclimation. The excessive ROS is regulated by the ROS scavenging system, which subsequently promotes plant tolerance. All these signaling events, including crosstalk between hormones and ROS, modify the plant's transcriptomic, metabolomic, and biochemical states and promote plant acclimation, tolerance, and survival. Here, we provide a comprehensive review of the ROS, hormones, and their joint role in shaping a plant's responses to high and low temperatures, and we conclude by outlining hormone/ROS-regulated plant-responsive strategies for developing stress-tolerant crops to combat temperature changes.
Steady as she goessssssss captain.
