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

Started LST

Day one of week 4. Nutes (BioBizz Grow) 50% of recommended dose have gone in today, I will increase the dose to 1ml for the next watering in 2/3 days. Will introduce BioBizz Bloom next week if no Nutes burn this week. Will do some more LST training tomorrow after another full 18 hrs of sun.. UPDATE - 13th September: Day 2 of week 4, gave the girls a very little trim and some more LST today.. New growth coming through nicely.. UPDATE - 14th September: Day 3 of week 4, Nutes (BioBizz Grow) went in today at 1ml per litre. A little more LST and I finally topped the girls 😍.. UPDATE: 16th September: Day 5 of week 4, 3rd lot of BioBizz Grow Nutes at 1ml/l per plant. Pleased with my four ladies progress so far! Peace ✌️🏼 🍃

Week 5 started July 24, 2022 Growth is still strong into week five, I see no pre flowering, I think that is because she started really slowly due to me getting used to this new light, etc. July 27, 2022 Smells like lime sherbet up in here. LST, light defoliation to get some light on the lower colas. Really watered in today for the first time soaking the media, she is stretching and I see maybe some hairs for pre-flower - hope not too too soon though, I'd like more height than nine inches before she fully stretched

[ Information ] For all grow information, including strain and room details, please see the first week of veg. [ Updates ] (Flower) Day 1 - Light intensity increased to 65%. C02 increased to 1300ppm average. Day temp/humidity 85/70 (1-1.2VPD), night temp/humidity 75/65 (.8-1VPD). Fed a diluted compost tea mixture before lights on. Base water was R/O and tap water mixed lightly with silica and Tribus microbes. Tea was a mixture of Fish Hydrolysate, Bat Guano, Molasses, Fulvic/Humic, Kelp, and Earthworm Castings. 8 gallons of tea were added to 72 gallons of water mixture for an 80gal batch total. The batch was mixed for a half hour before feeding to the room. I did not PH or PPM test the mixture, organic material is hard to get an accurate PPM reading so the numbers are useless to me. I will be working to bring the lights to 100% power over this first week of flower. Day 4 - Light intensity increased daily, currently at 90%. Will raise to full power tomorrow. C02 increased to 1800ppm average. Temp and humidity for day and night are still the same. Lights were raised slightly to maintain 12 inches from canopy height, and a few growth nodes that were above the canopy got topped. Watered today with an 80gal (1.25gal p/pot) mixture, 10% tap 90% r/o water. 6.8 PH, 2.2ec. Foliar sprayed yesterday before lights off with a neem mixture for weekly IPM. Canopies are stretching relatively evenly, though I will be adding in support nets within a few days to help maintain the even spread. I've run this strain before so I'm fairly confident that I know what to expect during these few stretch weeks. Day 7 - Lights have been at 100% since day 5. C02 still 1800-2000ppm on average. Plants are stretching quickly into the lights, I have yet to readjust their height. The best growth usually happens when I do nothing, and I've done almost nothing the past couple days besides enjoy the unusually warm spring weather my area is currently experiencing. Watered today, 100gal (1.5gal p/pot) mixture, <1ec. Mainly an organic feeding for microbe health, also wanted a bit more runoff than normal due to the high ec feeding previously.

Day 28- business as usual. May top dress end of this week, not sure. But smells and trichs are setting up and no signs of deficiencies. I probably could push them more but it’s all good for now. Day 30- ditched the trellis and did a heavier defol as the humidity would reach 73 with lights off. See if we can get some better airflow and fatter lowers.

Not much water just a drizzle and she seems to be doing better this week. She is only about 10 cm but she looks like she’s co

Late flowering smels is awesome like sweet and spiecy both on melane aroma tricome heads are coloured and ready to harvest

Diese Woche haben die Ladys einen schönen Wachstums Schub bekommen , sowie ihre ersten schönen Gesichter angefangen zu zeigen, Habe noch einmal schon entlaubt und 2 scrog artige Netze installiert um die gesamte Fläche zu nutzen. Frisches Futter gab es auch und sie entwickeln sich einfach wundervoll . Wünsche euch eine wundervolle Woche growdiary Community

Semana 8: Estamos en su ultima semana de vegetación. Despues de muchas apicales y desfoliaciones, decidimos probar el producto DELTA 9, el cual lo recomiendo ya que acelera el proceso de nuevos brotes y a la vez ayudará en su período de floración a que los cogollos sean mas resinosos y compactos. Despues de un lindo y largo trabajo de paciencia , las plantas quedaron con 32 puntas,. a su vez , se le realizó desfoliació de las hojas por debajo de las apicales para favorecer el crecimiento . En unos dias entran en flora. Nutrientes: kawsay Ph:5.9 Ppm: 1000 Semana 8.

Solo una parola..... CARINISSIMA!!!! almeno a me piace!

Hi guys been a way for a while but I'm back, the ladys are well into flower now. The strawberry chemdawg ogz are beasts and super frosty there a bit behind the blackberry moonrock. But alot bigger.

This strain is doing great and agent shown any signs of stress of deficiency she is doing great . Today I put her into the home she will stay in for the remainder of the grow and have given her some more nutes the organic kind and she loves it .. This girl is a great plant and will be full of surprises no dought. Cheers and thanks for checking in ...

Well they definitely made progress in the flowering dept over the weekend! I came back home to find a nice amount of bud sites and pistil growth all around. Bubba ya gotten so big it can’t fit under my lights in the tent with fan & filter, so it’s now been moved to the other tent. Kind of fucks with my auto grow I had planned, but not much I can do

Lo sapevo che il tempo aspettato sarebbe stato ripagato...sta volando

Hey guys back with the update, everything is going smooth the buds are forming very well. They're all golfball size. Just ordered a microscope so I follow up the trichome development. If I had to guess I'm gonna feed for a week and then I'll start flushing the ladies. I'll keep y'all posted and thanks for your support Keep on growing 💯🍀❤️

Really boring week, nothing changed, nothing exciting happened, just food and water. There's some really nice purples coming through the flower right now and I can make out the tell tale signs of the cookies on both phenos, they may not look the same but the smell coming of both plants is identical..
