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

The lower budsites have come in nicely over the last couple weeks and I finally got a digital microscope to inspect the trichomes. I have a few amber so far with some cloudy but majority are still clear. I think I have a week or two left before I chop her. She has one more watering+feeding left before I start the flush in about this time next week assuming I get some more cloudy+amber trichomes before then, if not I will continue with current feeding schedule until I'm satisfied.

Day 1 - Popped into glass of water. Will leave in dark warm place for 24-48 hrs till they sink. Day 2 - seed sank, now decided to place in paper towel, in a bag in the cupboard. Will wait 24 hrs for tap root to emerge and to 2-3cm this time. Day 3- transplanted into final 3gal fabric pot. Water only pH balanced. Day 6- still nothing to see, first time using fast buds... But the name is not doing this seed justice 🤦‍♂️🤣 hopefully she'll break through by end of weekend 🙌✌️💚 Day 10 still no sign of her. Marking it as failed to germ 🤦‍♂️💚

27/02/19 - This one is great, I popped the seed 24hrs after the gelato and this one seems to be developing its leaves a lot faster than the rest, so far really happy with DNA and with mills nutrients, it’s a lot easier to mix and I no longer have to use ph down because once all mixed it’s at a 5.8/5.9. 👌🏻 02/03/19 - Just transplanted all into their final pot, just in time I think as it looked like the roots were starting to circle at the bottoms of the pot, sprinkled half a tea spoon of Mykos on each hole prior to the transplant & fed them 2.5 litres each. I was going to saturate the whole pot but I’ll do that next feeding.

I swapped over to organic nutes part way through this grow cocked up with the medium I used anyway she's doing alright and has produced some very nice solid buds

WEEK 2 DAY 14 Since last week the babies have taken off! They didn’t have much light until yesterday when I added another 100w led and since then I’ve seen a huge difference ! They are looking super healthy the roots said fuck the pot and grew right through it I’m actually super interested in seeing how these grow up.. The 3 clones that were separate last week are now moved into one single pot to further develop the experiment. They are on the same feed as the mother with flora grow/micro/bloom and cal-mag . And In the last picture you can see my ghettos man way of cloning .. going to see which 2 out of 4 are better rooted and I will move those to a pot in about a week or so. If you guys have any questions or want to know where I got these exotic seeds message me!! Or comment below !

Esa familia, nuestras crazy cookies están algo sobre fertilizadas y por ello le practicamos un lavado de raíces para eliminar los nutrientes sobrantes. Ph controlado unos días sin regar la próxima semana y veremos que tal avanzan , floración lenta imagino que por culpa de la sobrefertilización aunque tiene solución fumetillas.

Well... week 3 these babies are really taking off.. I started all 4 on 1/8th dose of foxfarms.. all 4 taking about 20oz water each.

Another good week. Watered them twice. I'm not planning on feeding them again. A little defoliation. I definitely think they are in the last 2 weeks before harvest. Still seeing some nutrient burn developing on the leaves. I don't think I watered enough through the whole grow! I'd love to hear opinions on this! Took some videos of the buds with an iPhone 12 at 6X magnification. Decent quality! Otherwise, still looking to successfully harvest these plants! Thinking about the next grow. Probably going to be Auto Strawberry Cheesecake and Auto Anesthesia. Peace!
