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

Handled the transplant really well , she’s starting to branch out nicely. I’ll start some LST in the next week or so

(END OF QUARANTINE) Now I have put them to finish underground a 600w hps under 12/12 schedule with the Divine Black opium. Luckily no more mould has spread, and all plants look happy healthy and still developing. Day 72 12/09/24 Thursday De-chlorinated tap water pH 6 today with Plagron products. Finally a video and pictures update ✌️💚 Day 74 14/09/24 Saturday De-chlorinated tap water pH 6 only today Day 76 16/09/24 Monday Feed today using de-chlorinated tap water pH 6. Will update all videos and pics tonight 😁 Day 77 17/09/24 Tuesday Feed today using de-chlorinated tap water pH 6. Seeing good developments, buds forming nicely, divines are smaller denser structures but the buds are not lacking! Damn I'm surprised by 2L pots.

:)

08/30/2018 Day 1 of week 2 Flowers are developing nicely should be ready for pollination soon just waiting on little more buds,as I want a good amount of seedlings to choose from 08/31/2018 Feed Fox farms big bloom at heavy feeder dose 1/2 cup per gallon. Getting ready to pollinate maybe mid-week? Pistols popping up every where, almost ready for pollination. 09/02/2018 Not sure if Cherry Pie pollen will take did not look to good,but we will see,Mystery Cookie pollen looked perfectly fresh!

week 6 of flower and she is starting to put on the weight. Buds have not got more frosty, not sure if its the strain or I've missed something. We are going to go with it the strain and not me, LoL. RQS says 8 to 9 weeks for flower. We will see how accurate that is. i'm going to give some Silica this week to see if it will help with trich production.

The Plant was transplanted it 0.5 litre pot..

nous avons eu notre tente vivosun merci vivosun thank you vivosun

Durante esta semana la niña se termino de recuperar del estrés hídrico y tiene un buen pan de raíces. Aumento su consumo de agua y riego cada 3 o 4 días, intercalando riego de pura agua estacionada con ph 6,4 y 1er riego con fertilizante de vegetación. La niña crece frondosa con un gran tallo principal fuerte y grueso, y con poca altura. Realizo la primer defoliación y aplico un lst muy suave para permitir un mejor flujo de aire entre las ramas nuevas y mayor apertura de luz. La planta responde bien a la poda y el lst y se prepara para entrar en la pre floración-

Day 43 12/06/2021- Beginning of week five of flower. She should be done soon, she will also get her final feeding soon. Day 45 12/08/2021- She got her final top dress today from here on out she is on her own all I will do is water with pain water PH to 6.2-6.8 when dry. Day 47 12/10/2021- She is coming along nicely. Very frosty wish she wasn't a auto so I could of clone her for sure. Today she got a nice treat as it rain in my hometown and that's the water she got. Hoping she is ready by the end of the year. I know she looks funny but she was never topped either. Day 49 12/12/2021- End of the week, nothing new.

Defoliation week. Cleaned up under the canopy, and clipped the subpar Bud sites under the canopy. Foliar spray in use until end of week 4. Started to drop the temp to simulate changing of the seasons. 70*f during lights on, about 63*f lights out. Start of the week had an issue with the tent. After watering, the tent humidity went up to 90%. I have my Humidifier set to keep VPD between .8 and 1.2 and the system was trying to balance out between temp and humidity. Got cold one night. 3 days into this week and I haven't watered since last week. Soil still has plenty of water in it.

estos últimos dias estiraron bastante los apicales aumentando la distancia entre nudos. para bajar el PH utilizo ácido cítrico . El agua de grifo de base sale a 8,2 Ph y voy añadiendo hasta bajar a 6,7 áprox. A los 25 y 26 dias estas plantas poco deberian de crecer más y todas ya han elejido por donde crecer y engordar. Llegados a este punto quité alguna hoja y algún chupóptero y até algunas de las ramas a los tutores como buenamente se pudo. El fin no es otro que mirar de acomodarlas por donde seguir creciendo y no tengan que soportar ellas solas el peso que se les viene encima cuando engorden los cogollos. Como puede verse a una de ellas le salió una mutación genética llamada fasciación. una modificación cromosómica .

A nice week without problems i have added a few basil seeds, but posible way too much i migth have to remove them, have you grow other plants on your pots? any advice?

Esta semana ha ido super bien, está creciendo muy fuerte, sana y con buen color. cada vez tiene más pelos blancos esperemos que siga así #GorillaKing😍

Defoilated just a few leaves blocking some light. Increased the bloom nute just bringing my ppm and ec up in my runoff
