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

Didn’t manage to get a pic of all my autos this week cos we were in a rush. Will take pics of every strain on the weekend. Crazy smells coming of these plants now and they are getting very frosty. Will start feeding bottled nutes to make the most out of them.

Day 7 from light flip

plans have been ready since a few weeks ago but because I have other plants also in my tent I wanted to harvest them all at the same time I have given 36 hours to eat up on nutrients after the flush and now is Harvest Time thank you for reading and have a happy grow

I love this strain. Really strong genetics. Nice fruity and og kush like smell. Cant wait to harvest and try them.

Papaya cookies are incredible! All the pistils turn purple, incredible beauty of this plant. We are so happy to have caught this extraordinary phenotype and are looking forward to an early harvest in about 2 weeks time.

17.7 inches/week Usual summer week here in the south, every day above 86 ° F (max 100 ° F). By now the main cola is no longer dominant, my Gorilla is unstoppable , the youngest of the batch is grown almost 2 inches per day by drinking 2 gallons per day of spring water showing only few signs of heat stress. She's in full stretch and had fill every spaces with her thick branches. I fed her half the recommended dose of Biobizz Griw 'cause is too hot and don't want to burn her. I think we are 10 days before flowering. I covered her with a PVC net in order to give her a little shield from the sun and give me more privacy ;-)

🌌 Galactic Bloom – Auto Moon Rock Entering Her Final Orbit 🚀💫 Time flies, and here we are already in Week 8 with my beautiful Auto Moon Rock from Divine Seeds – now stepping into her fourth and penultimate week of bloom. 🌸 What a journey it has been so far! From the very beginning she’s shown herself to be a strong, resilient, and incredibly rewarding plant, and this week she continues to amaze me with her progress. The buds are swelling beautifully, stacking up tighter and frostier each day. Their density and aroma are reaching new heights – I’m experiencing terpene notes unlike anything I’ve grown before, absolutely unique and mesmerizing. The whole tent is filling with a fragrance that keeps me coming back just to breathe it in. One of the highlights this week is definitely the Growlapse video 🎥, where you can literally watch her day-by-day transformation. The footage captures how her colas are fattening up, pistils dancing under the light, and how she’s steadily pushing all her energy into flower production. A joy to watch and an even bigger joy to grow. 🌱 Feeding & Care This week I’ve kept things consistent and she’s been thriving under the same organic regimen as before: 🔸BioBizz Grow – 3 ml/L 🔸BioBizz Bloom – 2 ml/L 🔸BioBizz TopMax – 1 ml/L 🔸CalMag – 0.5 ml/L 🔸Dechlorinated water to keep the microbes happy No compost tea this round, just clean, balanced feeding. Her response has been fantastic, with lush green foliage and no signs of stress. ⚖️ Parameters & Environment 🔸EC: 2000 µS 🔸pH: 6.1 🔸VPD: 1.0 – 1.4 kPa The environment is dialed in perfectly, and she’s loving every bit of it. Strong light penetration, good airflow, and a stable climate are helping her buds reach their maximum potential. 🌬️💡 All in all, I can’t praise Divine Seeds enough – their Auto Moon Rock has been a rock-solid performer from the start. Despite being advertised as a strain not ideal for topping, she took training like a champ earlier on, and has rewarded me with a bushy structure that’s now turning into a canopy full of weighty, sparkling buds. I can wholeheartedly recommend her to anyone looking for an exotic terpene experience and a reliable autoflower with serious potential. 💎🌌 The end is in sight, and I couldn’t be more excited to see what the next (and final) weeks will bring. Harvest is creeping closer, and I have a feeling this one will be something truly special. 🙏✨

Last week for these ladies. Kept the soil moisture levels very low leading up and did a final heavy de leaf of pretty much anything that doesn’t have trichomes growing on it and will be shutting the lights and turning the heat off for the last 48 hours. Keeping a lot of the sweet leaf on to keep the moisture throughout drying and will do a dry trim. Will be aiming to have a long slow drying period (12-15 days hanging) before I jar them up for curing. Won’t be adding many quality pictures this week since half the time they’re in the dark but will post harvest pictures as they come down :)

Some are swelling , one is smelling very different to the others . I seem to have 6 phenos from small to tall and rounded buds to thin spear shaped buds. I'm not sure which is my favourite yet but one has a very unique smell almost like pineapple and exodus cheese , it could be that one but I also like the bud formation on another,, we will see

Second week of overdrive , and getting ready to flush for next next week res has been topped up and diluted down the mixture to ensure no over feeding or blockages happening and also to encourage the purple n black colours to come through . More comments said on the video as well

Another good week ticked off... No sign of fungus gnats since the daily neem oil and diac...’ earth. Seems to have done the trick but I stay vigilant! All the girls starting to fill out a bit. And getting covered in trichomes. Pics don’t do justice even the stems are covered. The other 2 plants in the grow stretched crazy and a bit later than these. Happily I think they’ve stopped. Nothing exciting planned from here other than a top dress later this week and just watering and an odd compost tea till the finish. Thanks for reading, have a great week 😊

Наконец примудрил обдув для растихи. На днях придет изолонтейп для шумоизоляции. Немного переделаю выдув и поменяю уголь в фильтре 6й день от перевода на 12/12. Растет активно, но я ее загибаю в ковёр, так как неоднократно были проблемы с недостаточностью высоты бокса. Так что пусть лучше будет поменьше)) По опыту могу сказать, что до зацветания ещё больше 10ти дней. За это время успеет несколько раз ещё порвать бокс. Лью сейчас удобрения Simplex Coco в минимальной дозе на вегу. Растению хорошо, и в дренаже ппм не растёт. Так что едем дальше))) Из проблем, только отсутствие нормального обдува для расты. Со дня на день придется что-то решать с этим.

Next week harvest!!!

10th week, the smaller Strawberry G was already harvested. 5 grams dry weight. Twig snap two days ago I was out smoked it. Head buzz, Strawberry taste was light and delicious. High lasted about 4 hours. I have a habit of harvesting with hardly any amber so the potency is at its peak.

What a quick and easy run! I always appreciate autoflower's speed, going from seed to harvest within 8 weeks always impresses me. Pretty happy with the flowers that I could recommend to novice stoners or as a daytime smoke. Thanks for stopping-by!

Gushers is looking good with the Spider Farmer G5000/UVR40 lights. She got the usual training today. Nothing else is really going on.
