A really explosive week of growth. I pushed PPFD up to 310umols. Dimmers are at 60% which is drawing 224w plus 18w of DRRB. I have alos started Emerson effect ... Another The Emerson effect is triggered by the simultaneous exposure of plants to light in the deep red and far-red spectra Deep Red 660 nm /Far-Red 700 nm . A bit of boring science that explains why you need both far red and deep red in order to trigger Emerson. The effect occurs because photosynthesis is driven by two distinct pigment systems working in series:Photosystem II (PSII): Absorbs energy most efficiently at shorter wavelengths (higher frequencies), like 680 nm (441 THz). Photosystem I (PSI): Absorbs energy most efficiently at longer wavelengths (lower frequencies), specifically 700 nm (428 THz). When you provide only the higher frequency (deep red), PSI becomes a bottleneck. When you provide only the lower frequency (far-red), PSII is not sufficiently excited to provide electrons. Providing both frequencies simultaneously allows both systems to work at peak efficiency, resulting in a rate of photosynthesis that is greater than the sum of the two lights used individually. To understand the Emerson Effect, think of photosynthesis not as a single engine, but as a two-stage assembly line. What is the Emerson Effect? Discovered by Robert Emerson in 1957, this phenomenon shows that plants perform photosynthesis much more efficiently when they are hit by two specific types of light at the same time: Deep Red (660 nm) and Far-Red (700+ nm). If you give a plant only Far-Red light, photosynthesis is very slow. If you give it only Deep Red, it's better but still limited. However, when you give it both at once, the total rate of photosynthesis is significantly higher than if you just added the two results together (1+1=3). What is Happening? (The "Assembly Line") Inside the plant's chloroplasts, there are two "workstations" called Photosystem II (PSII) and Photosystem I (PSI). They work in series, meaning the first one must pass "parts" to the second one. PSII (The First Station): This station is tuned to catch Deep Red light (660 nm). It harvests electrons from water. PSI (The Second Station): This station is tuned to catch Far-Red light (700 nm). It takes the electrons from the first station and uses them to create energy (ATP and NADPH). The Problem: If you only provide Deep Red light, the first station works fast, but the second station can't keep up because it isn't being "powered" efficiently by that specific frequency. This creates a traffic jam of electrons. The Solution: By adding Far-Red light, you power up the second station. It now "pulls" the electrons from the first station much faster, clearing the traffic jam and making the whole assembly line run at full speed. The Benefits for The Grow.. Because i am using the Biotabs water-only method, my plants already have a steady supply of organic nutrients. Implementing the Emerson Effect offers several distinct advantages: Increased Biomass: Because the "engine" is running faster, the plant produces more sugars and carbohydrates, leading to heavier fruits or flowers. Faster Finishing: Plants often reach maturity sooner because they have more surplus energy to complete their life cycle. Better Light Penetration: Far-Red light is very good at passing through the upper leaves. This "wakes up" the lower parts of the plant that would otherwise be shaded, allowing the whole plant to contribute to growth. Enhanced Secondary Metabolites: In many crops, this synergistic light can stimulate the production of terpenes and antioxidants, improving the "quality" (smell, taste, and potency) of the final harvest. The "Sunrise/Sunset" Trick I am using 4x Invisible sun Far red/Deep red bars,they use high-quality Samsung LH351H (660nm Deep Red) and specific Far-Red (730nm) diodes for 10–15 minutes at the start or end of the light cycle. This mimics the natural shift in light at sunrise and sunset, "waking up" the photosystems or signaling the plant to go into "sleep mode" faster, which can further optimize the flowering cycle. Enviromentally i am chasing a VPD of about 1,1kpa. My room seem to sit nicely at lights on at 24c with no real drama and a little help from a 220W greenhouse bar radiator. Its using abot 4kw/h a day atm because my room is attached to the side of my house and its been -5c.. I have had to add some humidity as its also very dry atm. Im aiming for RH of 65% with my 24c but it is more around the 62s.. VPD is crucial and is the focus for this grow for me. The autopots and Biotabs make it so easy ican really just focus on perfect enviroment. A VPD of 1.0–1.2 kPa provides enough "atmospheric pull" to move calcium and magnesium up from the roots, which is critical for the rapid cell division happening now.. Plants will be flipped on Saturday which is their week 5 as im a bit behind.. As this happens i will push PPFD upto 4-500umols. by week 2 of flower. Thats the plan anyway..

*This is not pictures of the 4 leaf baby*. That one died…moving on With This OG Kush auto pictured I haven’t done anything other than a few feedings and some water. I didn’t do any lst, topping or stress training. I am using air pots with some vermiculite, a bit of worm compost mix from local store, and a dash of 20/20/20 when it was a seedling.

Hello, my amazing green-thumbed friends! Welcome to the Week 1 flower report for our beloved P.C.R.s. The transition from veg to flower is a magical time, and our plants are already showing signs of their future glory. Let’s dive into the exciting details of this week! Entering the Flower Stage Our P.C.R.s have officially entered the flowering stage, and the transformation is already visible. The stretch has begun, and you can see the plants reaching up, preparing to produce those beautiful buds we’re all waiting for. This stage is all about supporting their growth and ensuring they have everything they need to thrive. NutriSpray Magic This week, we’ve been diligently spraying Aptus Holland NutriSpray, and the results are phenomenal. NutriSpray is like a spa treatment for our plants, providing essential micronutrients directly to the leaves. It helps with nutrient uptake, reduces stress, and boosts overall plant health. Our P.C.R.s are absolutely loving it, standing tall and proud with their leaves praying to the light. Nutrient Transition With the start of the flowering stage, we’ve made some important adjustments to our nutrient regimen. We’ve stopped using StartBooster and replaced it with TopBooster, which promotes flowering and bud formation. Additionally, we’ve introduced P-Boost, a phosphorus booster that enhances root development and flower production. TopBooster: Encourages larger and more abundant flowers. P-Boost: Provides essential phosphorus for robust root and flower development. NutriSpray: Continues to support overall plant health and stress reduction. Optimal Conditions Maintaining the perfect environment is crucial as we move into the flowering stage. Our TDS is now at 360, with a pH of 5.9 and a temperature of 21°C for watering. These conditions are optimal for nutrient uptake and overall plant health, ensuring our P.C.R.s have everything they need to produce those beautiful, resinous buds. Care and Attention Paying close attention to our plants during this stage is key. Regularly inspecting for any signs of stress or nutrient deficiencies and adjusting care as needed ensures our plants stay happy and healthy. The love and care we put into this process are reflected in the vibrant health of our plants. In Conclusion Week 1 of flowering has been all about setting the stage for a bountiful harvest. With the help of Aptus Holland NutriSpray, TopBooster, and P-Boost, along with our careful attention, our P.C.R.s are off to a fantastic start. The excitement is building, and I can’t wait to see how they develop in the coming weeks. Shout Outs A huge shout out to @aptusholland, our main sponsor, for their incredible products that keep our plants thriving. Another big thank you to @artgenetix for creating the phenomenal P.C.R. strain. And to the wonderful community at Grow Diaries and all our followers, your support and enthusiasm keep us going.

End of week 7 Last 2-3 days crystals/sugar leaves started appearing slowly. i have added another 125 Watt CFL for extra supplemental light . Breeder says plant needs 65-70 days from seed. Thats like 20 days more for the buds to get as big as possible. cant wait for this week to check these buds stay tuned :)

So i gave her last feeding of grow and bloom nutes at the end of week @1600ppm, Ph@ 6.5 and on the next ill only be giving ripen and drop the ph to 6.0 to fatten her up a bit more before i chop her. She's absolutely stinking up the place with some sweet gummy lemon gas coming thru. Think ill call this strain 🍋🍭Lemon lightning🍭🍋

Wow, another week done. It's become an absolute jungle in my greenhouse. A few of the GG4/Sherbets tops had to be mainlined since they're hitting the top of the greenhouse at 7ft8in tall. The smell is definitely getting stronger every day and it goes from super pungent, to sweet, to almost tropical. They're all still looking nice and healthy. The Athena Blended Line works wonders with my well water as the plants couldn't be happier. All in all Happy Growing.

Partially drained the tank at the start of the week and topped up with ro water and 1ml of final solution per Litre. Last 2.5 days were in darkness. I trimmed the majority of fan leaves before hanging up to dry in the tent today. Started out trimming with the plants in the tent and soon realised it would be much easier to just cut them down whole, hang them upside down outside the tent and trim them up a bit. I have a small dehumidifier and a small fan heater setup in the tent and they have been keeping a humidity level of about 60% and a temp of 16 Celsius for the last few days while the lights have been off. I figure that's a good starting point for drying and I can increase the temperature if needed, that will drop the humidity also. Intake fan at the bottom and extract fan at the top are running constantly as they have been since the grow started (low power 4" fans). I might add back in a fan for circulation depending on how the drying goes, or maybe even trim or hang the plants better to get more airflow around the buds
