Day 71 - Let the new week begin! Removed some fan leaves from the center of the plant today to create more air flow. Day 72 - Good run off today of 13%. Starting to notice the buds fattening up. CalMag decreased to 0.6ml/L. Day 73 - She looks really beautiful today. All the colas are starting to take shape. Day 74 - All the colas are taking shape now. Humidity in my area is high again putting the tent around 58%. Day 75 - Defoliated some of the inner fan leaves today, whilst doing so I touched some of the buds and they are smelling amazing! Fruity/Mimosa smell is already there and super sticky! Day 76 - She's taking up less water these days. My area humidity has gone up really high but still managing around 55% in the tent. I'll be monitoring her to see how she responds to the defoliation over the last couple of days. Day 77 - Getting really smelly now!🍊 That's the end of week 10! Pretty crazy to think! We'll be entering Week 6 of flowering tomorrow. The flowers look great and they are swelling out by the day.

@MephistoGenetics, Hi all the happy people here in GrowDiaries. This is my second cultivation ever and it will be fun to try a bigger space than my closet grow. First, I'm just going to say I'm done with the construction of my new growroom. The room is 2.14 meters by 1.7 meters and has a ceiling height of 2 meters. It provides a floor area of ​​3.6 square meters. I use a 54 Watt Lightwawe T5 for germination and 2 Pcs 400 Watt HPS lamps. I have a channel fan that replaces the room air about 40 times an hour to get a comfortable environment in the room, the air enters a fresh air intake from the outside. The air is purified through a carbon filter to then leave the room to the rest of the basement. Then I use that heat to heat the rest of the basement. I will use 10 pcs 15 liter Autopots to grow with and a 100 liter water tank that supplies the pots of water and nutrition. I will grow completely organically in soil and will watercure my buds to get the best possible medicine for me. But there are no cultivation rooms to be displayed here, so I continue with what is most important. Today I have put my seeds in paper towel and hope the seeds have germinated within a few days. I am very excited to see how the new growroom will work and how this Illuminauto 21 - Sour Crinkle will turn out. Illuminauto 21 - Sour Crinkle (Grape Crinkle x Sour Crack) Two of our fastest and frostiest varieties collide to make a sweet and sour delight! Expect super frosty, compact nugs that won't be a toke for novices. Destined to be a great strain for extraction work too! Plant size - Small - Medium Cycle time - 60-65 days from sprout Indica/Sativa - 80/20 Frost level - Extra Ridiculous https://www.mephistogenetics.com/product-page/illuminauto-21-sour-crinkle ................................................................................................................................................................................................................................................................................................................................................. 2017-08-21.

Sehr schöner gleichmäßiger Wuchs. Ich habe die Pflanze durch Supercropping auf ein relative homogenes Level gebracht und ich muss sagen. Es funktioniert einwandfrei. Außerdem habe ich die Haupttriebe mit Kunststoffbögen fixiert um weiteres abknicken zu verhindern.

Week 5, now we are talking, she is stretching and the roots are growing at a really nice rate. Feeding is almost at the recommended max without her showing signs of overfeeding, I always increase and try to push the plant but you need to go slow, step by step and see how she reacts, always give her 48 hours to see how she copes with the new dose, If she looks healthy stick to dose for the week and increase the following. A good trick to see if you plant wants more of less fertilizer is reading the ppm and check when the res level is lower after 3 days or so, if the ppm rises but the water level doesn't go down quick she has to much feeding. If the PPM stay the same or drop with quick water intake means she takes it in very happy and maybe can take more. Will continue to rise the dose till we reach the recommended max of 2.5ml/l, might play with the ratio later on.

A great replacement strain from Barney's. If you can't find the old exodus UK cheese which is almost impossible these days, this variant gives you everything you want. Definitely keeping this strain since its such an easy plant to grow. I have two more phenos to test with a full diary already begun! Thanks Everyone! First diary done 🎉 SM

The plants are starting to recover from the N excess 2 weeks ago, this delayed a bit the starting of flower from some plants but im sure that the rest of flowering will be ok, i gave only water this week and applied a small amount of guanokalong nutrients as these are slowly absorbed to ensure the plant continues to receive some nutrients until next 2 weeks when we will start to give some extra PK

Plants are 5 weeks old and I decided to switch to flowering for week 6. Plants are all in good shape and the screen is in place to train them to fill the tent. I will be changing out the veg bulb this week and installing the 1000w HPS bulb for flowering. I’m still playing with the light rail speeds and pause times but I seem to have it dialled in now I think. I will also be doing another water change and adding flower nutrients sometime this week. ****Added 7 gal of fresh water to the reservoir on day 38. Added full strength Remo lineup for flowering to the 7 gal added to reservoir. I started to tie down/tuck the larger branches to the net as well.

✨ Week 6 in bloom and our White Widow is pure poetry in motion — compact, dark, and sparkling with trichomes under her 11/13 light dance. She’s living proof that beauty and strength can thrive even under a 12-12 from seed rhythm. Join the journey, feel the energy, and come see her story unfold in 4K on YouTube. 🎥💚 🌿 White Widow – Week 6 Flower Lighting: 11/13 Shuttle (12-12 from Seed) Strain: White Widow by Zamnesia Grow Style: Living Super Soil + Aptus x Plagron Recipe Series: Ongoing on YouTube (in 4K 🎥) ⸻ 🌸 The Queen in Her Prime Our White Widow is officially in full bloom — Week 6 Flower, and she’s breathtaking. Compact, dark, resinous, and powerful — a perfect example of what’s possible when we trust the process. Her leaves are deep green, her buds are tight and frosty, and her structure shows the elegance of genetics and discipline combined. Despite being a 12/12 (11/13) from seed grow, she’s performing like a true photoperiod queen. Every detail on her — from the sugar-coated fan leaves to the symmetry of her bud sites — tells a story of health and balance. ⸻ 💡 The Emerson Effect — Science Meets Soul This week we’re diving deep into one of the coolest aspects of this grow: The Emerson Effect 🌞 Every morning, the red spectrum (around 660 nm) turns on 15 minutes before the main lights. Every evening, it stays on 15 minutes longer than the rest. Why? Because we’re mimicking nature — sunrise and sunset — and activating one of the most fascinating plant processes ever discovered. 🌱 What It Does The Emerson Effect is the enhanced rate of photosynthesis that occurs when red and far-red light (around 730 nm) are present together. In simple terms: red light excites one photosystem, far-red excites the other, and when both are active, the plant runs its photosynthesis engine at maximum efficiency. ⚗️ The Results • Faster and smoother metabolic transitions • Reduced light stress during on/off cycles • Increased photosynthetic efficiency • Denser, more resinous buds • Slightly faster maturity under 11/13 schedules We’re not just flipping lights — we’re syncing biology with physics. 🌞🌙 ⸻ ⚙️ Technical Deep Dive: Emerson Effect + 11/13 Light Shuttle For the enthusiasts — when using 11 hours of light and 13 of dark, you simulate tropical photoperiods where cannabis evolved naturally. This encourages faster flower initiation and more compact plant structure. By extending the far-red light 15 minutes on both sides of the cycle, we’re signaling the plant that the sun is just beyond the horizon. It’s like whispering: “Keep going a little longer, but rest well.” This combination strengthens the balance between flower hormone production (phytochrome response) and photosynthetic drive, leading to better overall bud development. Science + intuition = success. 🌿 ⸻ 💧 Feeding & Nutrition This week’s feeding schedule continues the successful Aptus x Plagron symbiosis. From Plagron: 🌸 Power Buds – flower development booster 🍯 Sugar Royal – enhancing aroma, oil, and terpene profile 💎 Green Sensation – late-phase bulking and resin enhancer From Aptus: 🌿 All-in-One Liquid – full-spectrum nutrition 💧 CalMag Boost – mineral support and stability ⚖️ Regulator – nutrient balance and plant stress protection Even with the soil’s natural nutrient reserve (NPK still holding around 5.75), we’re gently pushing — testing how much she can handle under this 12/12 rhythm. She’s loving it: no burn, no droop, no stress — just pure growth. ⸻ 🌡️ Environmental Conditions Even with 45°C (110°F) heat outdoors, the grow room remains stable and healthy thanks to proper airflow and control. 📊 Environment Stats: 🌡️ Temperature: 28–30°C 💧 Humidity: 55–60% ☁️ CO₂: 450–800 ppm (natural fluctuation) 📈 VPD: ~1.3–1.8 kPa This is near-perfect for mid-flower — warm enough to boost metabolism, yet steady enough to maintain trichome production. ⸻ 📸 Photos & Videos This week’s gallery includes: 📷 Detailed studio shots of her canopy and buds 🎥 Clips showing her daily environment 🌿 A moment of me sharing medicine with her — part of our daily ritual of connection and gratitude Screenshots from TrolMaster TM+ app, showing the red-light pre-dawn and sunset cycles Every frame captures her strength and personality. No micro lens this time, but the natural look says it all — she’s glowing. ⸻ 🔮 What to Expect Next Expect: ✨ Buds bulking and trichomes stacking heavily 🌬️ Aroma deepening and resin turning more opaque 🌿 Leaf color possibly darkening further Not to Expect: 🌱 Any major new growth — stretch phase is over 🍂 Fade just yet — that will come closer to flush She’s now in the consolidation phase: weight, flavor, and resin. ⸻ 🌱 Quick Recap • Germination: After early setbacks, she became the solo survivor — and a star. • Veg: Compact and steady. • Transition: Adapted perfectly to 11/13 shuttle. • Early Flower: Tight nodes, dense frost. • Now: Week 6 — full bloom, full potential. ⸻ 🙏 Gratitude & Shoutouts 💚 Zamnesia – for the legendary genetics that started it all. 💧 Aptus – for consistent balance and vitality. 🌸 Plagron – for the boosters that bring color and resin to life. ⚙️ TrolMaster & ThinkGrow – for giving precision and control. 🌍 And most of all — to you, the readers, growers, friends, lovers, haters, and believers — thank you. This community keeps the passion alive. ⸻ 🎥 Watch in 4K on YouTube 🌿 The full White Widow 12/12 from Seed Series is live in 4K resolution on YouTube.

Last days, getting fat and frosty. Switching to 24 hr for the final few days before chop. Last water was on day 85. I feel like I could actually wait another week or 2 but want to have some Xmas gift for friends so that clock is ticking. Easily 10% amber trichs at the moment and will likely get more with full light and no water for the next couple of days. Harvest coming right up!

So this week after I gave it under nutrients I apparently gave it too much nitrogen while having a potassium deficiency. Shiney dark leaves, So i fixed that, but some didn't bounce back, and I tried nitrogen. I think they are doing pretty good considering everything I've put them through SO FAR. lol. Nutrients are NPK Raw's total lineup, follow their instructions at first, Fastbuds adjustments as of this week.

Plucked a few more leaves but other than that just feed them this week including bloom. Also gave them some rice starch (from boiled rice water collection) on day 42 as a boost for the microbes 👍 Turned the IR off now and turned up to 34000lux

Vamos familia sexta semana de floración de estás apollo black cherry de SeedStockers. Que ganas tengo de ver el progreso de esta variedad, las plantas están sanas, se ven con buen color. La cantidad de agua cada 48h entre riegos. Esta semana añadimos nutrientes de la gama Agrobeta. Las plantas están bastante bien subió algo la temperatura esta semana pero por el momento no les afectó, a ver si consigo bajar un poco la temperatura estas próximas semanas y acabamos todo bien. Me pasé de mano con la comida pero solucionaré con agua destilada en un riego. Estas próximas semanas veremos como avanzan y como engordan las flores.
