Plants with more direct UV showed much more purple across all 3 plants. The data shows that the number of terpenes in dried Cannabis flowers increases with a “No Red” light treatment for the final three days of production. Based upon these findings, we feel confident in recommending a spectrum control program that eliminates red light output from fixtures for the final 72 hours of the Cannabis flowering cycle. Terpenes are aromatic compounds that give cannabis some of its most distinct aromas from citrus and berry, to more earthy tones. Many species of plants produce and emit terpenes in a diurnal, or daily cycle that is regulated by a complex web of signaling. There are also many plants that emit terpenes at night to attract nocturnal pollinators (Marinho et al., 2014346). Regardless of when the terpenes are produced or emitted, these processes are often dependent upon cues derived from natural light/dark cycles via a native circadian clock (Dudareva et al., 2004). Several light-sensitive pigments are involved in these processes of production and emission, and the different photoreceptors are dependent upon different wavelengths of light to be activated or deactivated. Emission of terpenes is a process that is entirely dependent upon phytochromes and red/far-red light cues in most plant species (Flores and Doskey, 2015). For example, repeated light/dark phytochrome signaling is necessary for the emission of terpenes in tobacco plants (Roeder et al., 2007). Based on previous findings, we hypothesized that a lack of red light and phytochrome-mediated light/dark signaling on the part of the plant is responsible for an increase in terpene content in cannabis. The plant continues to synthesize terpenes, but a lack of red light to trigger the Pr-Pfr shift results in a lack of terpene emission by the plant, thus causing the terpenes to accumulate in the maturing flowers.

Plant Mol Biol 65: 107-12 Abstract Sound waves technology has been applied to different plants. It has been found that sound waves were at different frequencies, sound pressure levels (SPLs), exposure periods, and distances from the source of sound influence plant growth. Experiments have been conducted in the open field and under greenhouse growing conditions with different levels of audible sound frequencies and sound pressure levels. Sound waves at 1 kHz and 100 dB for 1 h within a distance of 0.20 m could significantly promote the division and cell wall fluidity of callus cells and also significantly enhance the activity of protective enzymes and endogenous hormones. Sound waves stimulation could increase the plant plasma-membrane H+-ATPase activity, the contents of soluble sugar, soluble protein, and amylase activity of callus. Moreover, sound waves could increase the content of RNA and the level of transcription. Stress-induced genes could switch on under sound stimulation. Sound waves at 0.1–1 kHz and SPL of (70±5) dB for 3 h from plant acoustic frequency technology (PAFT) generator within a distance ranged from 30 to 60 m every other day significantly increased the yield of sweet pepper, cucumber and tomato by 30.05, 37.1 and 13.2%, respectively. Furthermore, the yield of lettuce, spinach, cotton, rice, and wheat were increased by 19.6, 22.7, 11.4, 5.7, and 17.0%, respectively. Sound waves may also strengthen plant immune systems. It has been proved that spider mite, aphids, gray mold, late blight and virus disease of tomatoes in the greenhouses decreased by 6.0, 8.0, 9.0, 11.0, and 8.0%, respectively, and the sheath blight of rice was reduced by 50%. This paper provides an overview of literature for the effects of sound waves on various growth parameters of plant at different growth stages. https://doi.org/10.1016/S2095-3119(13)60492-X

DAY 36 All right got some aggressive growth this week. Sorted out the mag and calcium issues for the most part. Few plants are still showing minor deficiency symptoms. Punch Line #1 is a male. Identified at day 31 or so which is crazy to me that it showed signs that quickly. Put him outside - will initiate reproductive phase and I will harvest pollen in 3-4 weeks hopefully. So I used these LST clips I’ve used on dozens and dozens of plants now and they went on fine. But when I came back 12-24 hours later they had snapped the fuckin plant stem on the branch it was on. WTF. So one plant - #5 - has only one node left cuz it snapped its own branches!! So crazy man. I’m debating when to initiate flower on these babies. They’re gonna be beasts if I go much longer in veg. Probably won’t be able to do all these in this 4x4 realistically These are easily the best looking plants I’ve seen at 30 days in. Stalks on these are massive for their age. Nodes are huge and tight. Fan leaves bigger than my hands. Big ups to ETHOS on these. UPDATE October 1 - punch line to 12/12 Stay tuned and check out my Instagram @ezzjaybruh

I pistilli iniziano a colorarsi di arancione ed anche cime e foglie iniziano a prendere un po' di colore, per il momento la pianta con il top è la più colorata ed è bellissima, continuo con i fertilizzanti per sfruttare queste ultime settimane per recuperare un poco

She’s coming around but I believe the yield is very low. Learning experience with this one. She was neglected and stunned many times

First set of leaves were a bit light and what appears as some decent tip burn? Bucket was running hot on week two, but left it alone. She’s happy now that she’s starting to get the munchies. Most of the growth is looking decent. I’m going to top above the fourth node, and take the lower branches leaving 6 main branches to train. She’s topped but it looks like I will end up with 8 branches to play with. I may remove the bottom two?

Looking nice 👍 I will transplant into 19 l this week Could this b3 the rarest of rare ? Is this the triauanna plant ? 🌱 OMG IT COULD BE THE ONE Before everyone tells me how wonderful they’ve had a triple Leaf before , that might be the case but you’ve never had a triple Stem structure , EVERYONE has had the plant with three primary leaves , that grow funny , and end up normal , if thus is a true triuanna plant it’s so strong 💪 we will see Change reservoir Fridays 75 cm away from SF4000 30 cm away from SF1000

Hello Growers 👋 👋 👋 At last I am doing an update 😇 It's Day 49th big changes occur in my tent. NYC diesel is still the smallest in the team but like her sisters start showing signs that the bloom will start soon 🌻 🌻 🌻 She is more sativa then her two sisters, I hope extra weeks on bloom stage make her big and tall 😁 🙏 😇 Please have a proper afternoon rest 🙏 You Lovely Girls Growers 😇 🌻

She is definitely bushing out smell increasing definitely a good cultivar

Now she is spread out more the larfy buds may bulk up slightly before I chop her down. Tops are pretty much done looking at the trichomes, just them lowers I want a bit better. Maybe another week. Back soon. Take it easy.

Another rough week. Thought I got aphids but now as I'm posting this after some more research it looks like I may actually have Neoseilulus fallacis. I only sprayed them down with water and got lady bugs. Been sick the last week as well so I cant really smell whats going on. Been having a hard time keeping the humidity below 60% at night but i finally found a budget dehumidifier that works okay

Normally I allow two days in the paper towel germination. This one after only 24 hours.

Got the guy separated and hopefully the other three are female so I can still flower two of them. Will be doing small pheno hunts with this strain in the future so ill be needing the seeds.
