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

Discount code NINJABUDS: Air cube GROwACE.com Discount code NINJABUdS: ELUfAH Everything looks healthy for now. Nothing big to update yet I have not chosen which 6 plants I’m going to keep yet. I’m only going to keep one plant of each strain

The candy cush bounced back with resilience this week after the transplant. She is about to go into stretch and seems to be doing well this week.

La verdad que esta semana e notado mucho el cambio se han puesto las flores mas redondas y duras como piedras por no decir la olor que echa

4/9/25 This plant is beyond frosty. Stacking up super nicely. Seems like she will yeild quite a bit. My only gripe is that she has like no smell at all. Using the foil as a soil cover is working quite nicely. the top soil is getting filled with roots quite well. Top dressed 1tsp of Bloom 1tsp microbe charge 1tsp bloom

So I transfered them today a little ahead of time but nothing wrong with that! Roots looked amazing! Added dynomyco into medium on final pots and watered 500ml of solution!

Week 11 Jan. 13 - 19, 2020 Jan. 17, 2020 I'm a few days late updating week 11. So here it goes. I harvested the 3 Zkittlez plants. I enjoyed growing these. They didn't get as tall as I'd liked but that was my fault, I kept my lights too close during the early stages of the grow. I learned that these auto flowers don't not need to be LST'd. My Zkittlez #1 I over stressed and it yielded out only half of what the other plants did. Of the other two plants...one was LST'd and the other was left to grow more naturally with very little training. They both yielded within 1 tenth of an ounce of each other. Final dry weight is 2.5 oz. Could've been better, but it's my first time and I learned a lot. Here's a link to my diary for Zkiitlez if you'd like to check out my first grow experience in more detail. https://growdiaries.com/diaries/44659-fastbuds-zkittlez-auto-grow-journal-by-weedwacker/week/212148 Looking forward to harvesting my Californian Snow plants which still fattening up and putting on major trichomes. No amber trichomes but wow the plants are frosty and they have a strong pungent smell. When the main cola is bent a little sideways it really begins out the smell. The smell is like a gassy fuel, diesel fuel, strong chemically smell. I love it. CS #3 is giving me some problems. The pics might show it. The leaf tips are curling up and thr leaf edges are turning brown. Not sure if I can correct this befor harvest. It's late into flower. I may just ride it out until then. I've topped dress once weekly for the last 4 weeks with kelp, and a blend from roots organic for bloom 4-6-3.

they are all growing great and starting to get taller. a very robust plant and very easy to grow and maintain. they are getiing 1/2 the recommeneded dose of nutrients 3 times a week

Some of my beauties have little bit iron defficiency but.. i just bought FE+ nutritions So IT ill be fine i think Soo ..

Growing without issues. Feeding every 2nd day now. Shes requiring much more nutrients. Switched her to 20/4 light cycle as well. Trying to speed up her growth as she's moving slowly.

PAR 450 PPFD It's all about creating new branches during these weeks of vegetation and LST for me is the best way to achieve that. More branches means more Green Gelato cones at the end of my grow. I try to create about 20 per plant at the end of vegetation.

Seedsman 420 grow off! I was sent a pack of blueberry pie f1 fast seeds and I am germinating 1 seed to fill my tent. I already have 3 gorilla gas seeds going and I wanted to do grow another blueberry strain so I'm really excite for this one too. This tent is gonna be filled out with some really nice flower in the near future.

Apparently the plants have stopped growing taller and now the buds are going fat which is a really good new :D:D:D - The buds are developing good amounts of resin too The smell is stronger now , i don't what is the smell like but it is definitely nice . Day 72 and according to seed vendor it will be ready between 70 and 80 days from germinating so this weekend i will move it outside the tent to observe the trichomes Day 73 - I moved the plants outside to see how it goes and i have decided to remove plant 1 from the tent(is wich i did the topping) due to small size which made nearly impossible to develop buds. The others are great and the 2 where i super cropped multiple times are mora than 100 cm each so i think their real height should be 120cm in a bigger tent. Buds are going heavy everywhere

🌸🍏✨🍭🌸🍏✨🍭🌸🍏✨🍭🌸 Hi and welcome to another Kannabia grow! This time I’m running their Apple Fritter (feminized photoperiod). She’s going to veg under 24hr light and be manifolded.

Ended up with 12 tops, was aiming for less, but she made the call Didn’t fight it, just shaped it the best I could Airflow’s good, structure’s stable 🛑 No more cuts until post-stretch Pics coming shortly 😘 Flip coming soon — we’ll see how she handles it. 20.06.25 VW9 Switched lighting to 12 hours, may the stretch begin 🤞 22.06.25 VW10 Did a good LST session,made some pics, and came to some conclusions and a small change of plans: Originally planned for 8 mains — long, spaced colas and maybe a couple stronger “titans” if she wanted to go that way. But she’s showing me something else, and I’m not here to fight her — just guide her. Now after stretch, I’m keeping side shoots only if they: Fill real canopy gaps Don’t crowd neighboring tops (minimum 15cm spacing) Aren’t growing into walls or toward the next plant Anything too close, too low, or heading into shade gets removed. No point forcing it. Looks like I’ll finish with 14–16 solid tops, depending on how she settles. I’m just trying to give each one enough light and space to stack properly. No overcrowding, no larf — just letting her do her thing with a bit of structure.

Super boof is doing amazing like expected. The nodes are real close and stacking well medium size leaves with fast growth and a super strong smell. I bet this one finishes fast it’s ahead of the others All of the plants have really taken off. Usually I have a couple plants that are much smaller but all of these plants are getting huge. Seeing I got a new eluefah uap1500 the other day and I have my 2 fastbuds plants under that now I have my spider farmer light free. So I popped up another 2x2 and moved 3 of the 10 plants into the 2x2 and left the 7 other in the 2x4.

18 hours of light = 64,800 seconds 624 μmol/m2/s from the PAR meter Micromole μmol/s (micromole) is the unit in which P.A.R (Photosynthetic Active Radiation) is expressed. This unit indicates how many micromoles per second a light source emits. μmol/s is one-millionth of a mol (10−6 mol). 624x64,800=40,435,200
