Mephisto and Dutch Passion

SpliffyRand After a successful germination process, the four little seedlings are growing steadily. The only one that gave me a bit of trouble was the Headbanger. During germination, it started with its taproot growing upside down, so I had to carefully adjust it. Now it’s the smallest of the group, but it looks like it has recovered from its rough start. I’ll let the Headbanger keep going even if it might end up being the runt of the round. If there’s life, there’s a way, right? Lamp: Set to 25%, 40cm distance Watering: 20 light sprays of water for each seedling every day

SpliffyRand We’re at day 12 now and they’re all still pretty small, especially the Headbanger, just as I mentioned last week. Growth is steady, though a bit slower than expected. Today I gave them their first feeding of BioGrow, around 250 ml per plant. Next time, I’m planning to increase the amount to 1 liter each. I’ll set up the Blumat dripping system and add the BioTabs once they start drinking more. For now, I think the BioTabs would still be too strong for these little ones. Better to take it slow. Light: SANlight @ 40%, ~40 cm distance. Gradually increased from 20% to 40% in week 2 (+5% every 2 days)

SpliffyRand Giving 750 ml last week was too much. Note to self: increase watering in smaller steps next time, about 250 ml at a time. On the next run, I’ll go from 250 ml to 500 ml per plant instead of jumping higher right away. That’s exactly why I’m documenting everything here: just learning and optimizing the small details. But as always, every plant reacts differently, so you always have to adapt. Growing automatics and changing genetics every time makes it hard to maintain a real routine — it’s like starting from zero with every run. Maybe one day I’ll stick to one strain over and over again, but for now, I’m enjoying the process of discovering the world of beautiful flowers and unique terpenes. As you can see, the Forum Stomper × Sour Crack is praying just like the Xtreme Haze, while the other two aren’t doing it in the same way. Maybe it doesn’t even mean they’re unhappy. It could just be genetics. Either way, I know when to water them next. Finding that sweet spot isn’t easy, but screw the sweet spot! It’s Day 19, and these plants are looking pretty damn good. The plan stays the same: -Water when necessary -Aim for a happy, maybe even praying, look a day after giving 1 L per plant, mixed with 1 ml/L BioGrow After that:-Add one BioTab per pot -Install the Blumat drip system -Go fully hands-off -A week or two later: add another BioTab This report was presented by Blue Applez. A nice strain for journaling 👽

SpliffyRand Day 25 – Welcome to the Jungle! The stretch has officially started, and the plants are doing great! Two of them, FS × SC and Dead Lot, are already getting really thirsty, easily drinking about a liter every three days. I’ll probably hand-water them one last time tomorrow and then install the Blumat dripping system around day 30. I can already see a few pistils popping up here and there, so the pre-flowering phase has begun. If things keep going at this pace, they might hit full bloom by week 5!

SpliffyRand Day 32 - System Online Just as planned, I finally installed the Blumat dripping system on Day 30. Now, on Day 32, everything is adjusted the way I want it. After installing the Blumat carrots, I spent some time finding that sweet spot where the water drops hang at the hose tip without falling immediately. A few hours later, the drops started to fall, then stopped again as soon as the soil reached the right moisture level Before installation, I gave all the plants a final manual watering, using 1 ml/L of BioBizz GrowMix and one BioTab per pot. Roughly 1.25 L per plant. A day later, I installed the carrots. So far, the plants are responding very well to the combination of a single BioTab and the drip system. In about a week, I’ll add another BioTab to each pot to keep things slow and steady. During my last autoflower run, I added two tabs at once, and they got a little too much nitrogen, so this time I’m applying what I learned. One step at a time. According to Mephisto’s strain info, the whole cycle could be done in about 40 more days. Still, I’ll stick to my rule of thumb and aim for harvest around Day 84, which lands on December 17th. Perfect timing for Christmas! Twelve weeks on easy mode. Quick Stats Day: 32 Light: SANlight @ 60 % Temp: 23.1 °C rH: 49 % VPD: ≈ 1.44 kPa Water consumption: ~8 L in 3 days → ≈ 0.67 L per plant per day → (8/3)/4=0,666L Next step: Add 2nd BioTab on D40-45

SpliffyRand Day 39 – Frost shows up This run is starting to feel almost too easy. From now on, all I really have to do is refill the water reservoir and watch them do their thing. After I noticed a bit of yellowing on the lower leaves, I decided to add the second BioTab on Day 36. So far, that was the right move. A little fade from the bottom isn’t worrying me at all – it mostly tells me the plants are actively using what’s in the soil. You can also see it in the water consumption: they’re drinking more than before. Right now they’re taking in about 10 liters every 3 days for all 4 plants, which is roughly 0.8–1.0 L per plant per day. Since the Blumat carrots are regulating individually, it’s hard to tell which one is the thirstiest, which is exactly how it’s supposed to be. The stretch seems to be done for all of them. Funny enough: Headbanger 505 stretched a few extra centimeters this week and is now the second tallest plant in the tent. Considering I almost tossed her after the awkward germination, I’m really glad I kept her. She’s a beauty and just a few days behind the others in flower development. ±45 days to go – perfect timing. Going to be an epic Christmas harvest for myself. Quick Stats Day: 39 Light: SANlight @ 70% Temp: 23.1°C rH: 61% VPD: ≈ 1.10 kPa Water consumption: 10 L / 3 days / 4 plants → ~0.83 L per plant per day Feeding: 2× BioTabs per pot (2nd tab on Day 36) System: Blumat drip – stabilised Medium: BioBizz Light Mix Flip-to-harvest plan: ~45 days left → Harvest around Dec 17 Next step: I’ll add some beneficial insects as a preventive measure. I brought a plant in from the balcony earlier this year, so I’d rather be safe than sorry.

SpliffyRand Day 46 - It’s Getting Stinky After applying the beneficial insect sachets, I didn’t spot any of them on the tops at first, but I did notice some suspicious marks on a few leaf fingers here and there. After reading a bit more about how to use beneficial insects properly, I decided to open one sachet of each type and scatter them loosely over the canopy. You can see the flakes in most of the pictures. They look a bit like dried hay. Now, a day later, I can finally see some results. In picture #2 you can clearly spot an Amblyseius californicus. These little hunters are known for preying on spider mites, and I’m confident that, even if the marks I saw were caused by mites, there’s no real threat to this grow anymore. From now on, beneficial insects will definitely be a must-have for all my future runs. As for the plants’ development, they’re doing fantastic. Considering the minimal effort I’ve put in (basically zero), they’re absolutely thriving. Sure, some rusty spots have appeared here and there, probably from a light phosphorus deficiency, but that’s no big deal. This grow is supposed to be hands-off, and that’s exactly what I’m doing. The plants are right on track, and judging by their current appearance, they’re going to be straight fire. When inspecting Dead Lot, I’m already a bit intimidated. The pistils stand upright like the plant’s a living flame, or maybe even a Super Saiyan. The same trait shows up on Headbanger 505. Both look stunning. And this week, the smell really kicked in. They’re getting insanely stinky in the best possible way. I can’t quite identify the terps yet, but it’s definitely something special. Last note: the Blumat dripping system is still running flawlessly. Sometimes the pots feel a little too heavy, but the plants seem happy with it, so I’m not touching a thing. Quick stats: Day: 46Light: SANlight EVO 3-80 @ 75 %, ~40 cm distance → estimated PPFD ~720 µmol/m²/s, DLI ~47 mol/m²/day (18 h) Temp: 25 °C (increased heating in my grow room) rH: 50 % VPD: ≈ 1.20 kPa Pest management: Beneficial insects (Amblyseius californicus and cucumeris) introduced and active Development: Stretch complete Harvest: ~38 days left

SpliffyRand Day 53 – Waiting for Harvest Nothing much this week besides monitoring. Conditions are steady, the drip system is behaving perfectly, and the plants are happily drinking. I added another round of beneficial insects as a late-flower precaution against pests. Judging by Dead Lot and FS × SC, harvest doesn’t feel far off. I doubt they’ll need a full month from here. A lot of Mephisto runs I’ve seen wrap up around ~day 75. Let’s see who finishes first! Ideally I’d like to harvest all plants together so I don’t have to dry/trim in multiple rounds. For now: let them thicken up and ripen fully. Quick Stats Light: SANlight EVO 3-80 @ 75%, ~40 cm distance, 5% tilt, 18 h → estimated PPFD ≈ 720 µmol/m²/s → DLI ≈ 46.7 mol/m²/day Temp: 25 °C rH: 55% VPD: ≈ 1.30 kPa (calc with leaf ≈ air −1.5 °C) — great for mid/late bloom Pest management: Fresh sachets applied; occasional spider-mite traces only, predators (Cucumeris & Californicus) active
