Refurbished soil HVAC system, and increased airflow. To maximize your yield, always aim for 40 moles, or 40,000,000 μmol, per day. Here is how much PPFD is needed per second for each phase of cannabis growth to achieve the DLI of 40 moles of light per day. I picked up a Quantum PAR Meter, very happy!😁 PAR Meter will show me how much useful radiation between 4-700nm the plant is getting from any given direction. Seedling phase (18hr cycle): 200–300 μmol m-2 s-1 Vegetative phase (18hr cycle): 617 μmol m-2 s-1 Flowering phase (12hr cycle): 925 μmol m-2 s-1, (1500 μmol m-2 s-1 @1500ppm co2) (ballpark). Anything above 2000 PPM is harmful to both the grower and the crops. The tent is currently reaching 3-400umol ms 1s at soil level (42" inches from light) and 1100umol-1300umol @ 25" Inches.

Welp, this is not a September plant😆 This girl is still going for at least another week. Pistils are starting to brown but trichs are still clear and cloudy, no amber yet. I'm hoping to get a little more sugar on her before she finishes. Hopefully it doesn't get too cold and rainy before she's done. All I can say is that I've been impressed with how strong this plant is and I'm looking forward to seeing what kind of numbers she puts out. She's been very healthy and easy to care for so I'm happy so far! She has a little bit of a spicy undertone, so definitely high in Myrcene (which is a pretty safe assumption) and maybe caryophyllene.

The outdoor grow continues to come along nicely! Temps were up last week, getting in the 30's with the humidex, so the ladies got some extra water. Thanks for stopping by growfessors 👽🌳💚

Esta semana notamos que los Led estaban demasiado cerca de las copas cuando los apicales mostraron un inicio de albinismo así que tocó alejarlos un poco, a 40 ctms áprox. igual poco menos. Las dos Amarettotarmac muestran una diferencia notable en la morfología de los cogollos pero de olor ambas afrutadas, cereza, fresa, algo muy rico y notable a larga distancia, que huelen mucho. xd

Clones taken from my last LH currently flowering outdoor diary. vegged under 50-50 sun and led. Now transplanted to 5L pot and 1.5 weeks more vegging under led and then will go to flower Led setup is 1 Mars Reflector 192 along with two units of BloomSpect 300 veg under veg switch on mars with bloomspect (only on-off switch) will flower with bloom switch on also. bloomspect true watt is 130w Mars true watt is 280w veg and 450w veg w/bloom

Week 3. This is where the fun begins. The smell is amazing. The stretch is crazy and the stems are stiff like bamboo. There's no loss in terps. They're actually getting a lot stronger!!

Hope you are well. Thanks for taking the time. Little main line defoliation to focus growth. A cell is a quantum measuring device for light’s frequency to make order from the chaos that light frequencies bring from our environment. A cell performs mechanical resonance, where its intrinsic structures vibrate at specific resonant frequencies when exposed to external mechanical stimulation. Cells possess the ability to sense and respond to mechanical cues from their environment, a process known as mechanosensing. This can involve the activation of signaling pathways and changes in gene expression. Cellular resonance is a component of mechanotransduction, the process by which cells convert mechanical force into a biochemical signal that triggers a cellular response. Plants perceive mechanosensory stimuli, such as vibration and touch, through structures like trichomes (hairs) and specialized ion channels embedded in their cell membranes. Plants are sensitive to frequencies ranging from ultrasound to lower sound waves, such as 250 Hz. The perception depends on various factors, including the stiffness of the underlying tissue, which can be tuned by the plant to perceive specific frequencies associated with environmental cues like insect herbivory. While the exact molecular mechanisms are still being explored, scientists have identified several potential pathways that may be affected by acoustic vibrations in this frequency range: 4000-5000 Hz. Enzyme activity: Sound waves can increase the activity of certain enzymes, such as amylase, and elevate the content of soluble sugars and proteins. Increased stomatal opening in response to specific frequencies can optimize photosynthesis by increasing the plant's absorption of water and CO2. In addition to enhancing drought tolerance, sound vibrations can strengthen plants' overall resistance to stress. Studies have shown that some genes related to stress response can be activated by sound stimulation. The Emerson effect is a phenomenon where the combination of red and far-red light increases the rate of photosynthesis beyond the sum of the two wavelengths used separately. This synergy is important for understanding Extended Photosynthetically Active Radiation (ePAR), which includes the far-red spectrum, because it means a more comprehensive measurement is needed to fully understand light's effect on plant growth. ePAR meters measure light up to 750 nm, which is necessary to capture the far-red light that participates in the Emerson effect. The human eye can detect more shades of green than any other color due to a combination of our cone cell sensitivity and evolutionary history. Our eyes are most sensitive to the yellow-green part of the spectrum, which is the peak of our visual sensitivity, and a large part of our ancestry was spent needing to distinguish subtle variations in greenery for survival. or our primate ancestors, being able to discern subtle differences in green was crucial for survival. It helped them identify edible plants and avoid poisonous ones, as well as detect predators hiding in foliage. This constant need to distinguish shades of green drove the evolution of our color perception to become most sensitive to it. S-cones: Detect short wavelengths, perceived as blues and violets. M-cones: Detect medium wavelengths, perceived as greens. L-cones: Detect long wavelengths, perceived as reds and yellows. The primary reason for our enhanced sensitivity to green is that the peak sensitivities of the M-cones and L-cones are very close together in the green-yellow region of the visible spectrum. This overlap means that green light stimulates both the M-cones and L-cones, creating a more robust and detailed signal for the brain to interpret. In contrast, the S-cones are more isolated and respond to a much narrower band of light, leading to less sensitivity for blues. The brain's visual processing pathways also play a role. Our visual system processes color differences through "opponent channels," which compare the signals from different types of cones. The opponent channel that processes red versus green has a more precise and intricate system than the blue versus yellow channel, leading to finer discrimination in the green part of the spectrum.

1 day of 9 flowering week: They look nice even with 3 weeks calcium deficiency and still swelling. I only water these plant with water ;). In one of the Hulks a blueberry breaks through i see on the leafs. Smell is really strong, thick and rich in terps. 3 day of 9 flowering week: Going to mature, dying very rough 7 day of 9 flowering week: One SB is out, next day is last of their lives, next week: Harvest!

Week 8 for Mango Merengue, week 7 for Afghan Hash, and week 6 for Sour Diesel. I'm taking down Pheno #1 of the Mango Merengue today, it was faster to mature then Pheno #2 & #3. Pheno #2 & #3 have around 1-2 weeks left of flower. Mango Merengue - Small to Medium buds, strong Gassy/Melon smell, and packed with trichomes, average flowering time 8-9 weeks. Afghan Hash Plant- Medium buds, packed with trichomes, and has a Sweet/Earty smell. Average flowering time 8-9 weeks. Sour Diesel - Medium to Large buds, also packed with trichomes, really close bud formation, smells Gassy/Sweet. Average flowering time 10 weeks.

July 19: first night of force flowering last night. Plants in dark garage at 9:30 pm and out again at 7:30 am for 10 h darkness. Also using 730 nm far red light at transition to dark which puts the plant into dark mode two hours faster so it’s like getting a 26 h day with 12 h of darkness. Force flowering for 2-3 weeks to make a solid transition into flowering and to get the buds ripening under the stronger summer sun. July 22: Foliar spray with Epsom salts and potassium silicate this morning. The magnesium in the Epsom salts seems to help with yellowing on the new growth. July 23: added another loose Scrog net layer. Tied to water bottles to open up the canopy to sunlight. July 25: watering yesterday included some water leftover over from steaming beets for dinner. That likely contained lots of N because beets are high in nitrate and the plants are very green this morning.
