Miketama Soil Preparation & Organic Amending (20L Fabric Pots)
Recycled Substrate Base: Reconditioned 15L of used light-mix soil per pot.
Nutrient Dry Mix: Thoroughly mixed 110g of Monster Bud Mix, 40ml of Startrex, 20g of Bat Guano, 3g of Mycorrhiza, and 1â2 handfuls of fresh worm castings (humus) into the lower 15L substrate layer.
Slow-Release Core: Placed 1 BioTab per pot at a depth of 10cm within the lower layer, positioned well away from the central stem.
Biological Activation (Lower Layer): Activated the microflora in the old substrate using a solution of Bactrex and Orgatrex, bringing soil moisture to approximately 25% Water Holding Capacity.
Fresh Top Layer Buffer: Covered the amended base with 5L of fresh, unamended Light-Mix soil to create a safe zone for early growth.
Planting Hole & Seedling Zone: Added 3g of Mycotrex directly into the seeding hole and lightly watered the top layer with a diluted Bactrex and Orgatrex solution for instant, safe mycorrhizal colonization.
Irrigation & Nutrient Management Strategy
Base Regime: Water-only routine using decanted tap water for standard daily watering.

Miketama Week 2 Vegetative Summary (Day 17 Plants)
âFoliar Nutrition (Vita Race):
Spraying Vita Race supplies organic iron and key trace elements directly through the leaves. This boosts chlorophyll synthesis, accelerates photosynthesis, and deepens greening to maximize energy production right before the stretch.
âLight Metrics & DLI:
Operating on a 22/2 schedule at 220â250 PPFD, the plants receive a DLI of ~17â19 mol/m²/day. This long photoperiod provides steady daily energy while keeping heat under control and avoiding light stress.
âCanopy & Structure:
The 17-day-old plants are actively establishing their 3rd and 4th nodes with full multi-fingered leaves, building a broad surface area to capture light as they approach the transition phase.
âRoot Development:
Root growth in the 20L pots is accelerating rapidly underground, anchoring the plants and building the capacity needed for upcoming heavy nutrient uptake.
âNext Phase Setup:
With a strong root structure and healthy foliage established, these plants are fully primed to handle a gradual increase in PPFD (towards 300+ Âľmol) as they enter their pre-flower stretch in the coming days.

Miketama Big Demon Auto â Week 3 (Day 22)
âStage: Late Vegetative
âStructure & Development: Remaining noticeably squat and bushy with tight internodal spacing. Energy is evenly distributed across the main stem and central side branches. No pre-flowers visible yet.
âTraining & Maintenance: Too compact for LST at this stage. Removed a few lower baseline leaves touching the substrate to prevent moisture buildup, optimize airflow, and keep the soil surface clean.
âFeeding & Additives:
âPlagron Pure Zym (1x/week): Applied to keep the root zone healthy, clean up organic waste in the substrate, and prepare the root mass for the upcoming bloom phase.
âPlagron Vita Race (1x/week): Applied via foliar spray for essential iron and vitamins, supporting overall plant vigor.

Miketama âPhase: Late Vegetative / Pre-Flower Transition
Lighting & DLI: 22.5h Photoperiod (22h @ 400 PPFD + 30 min sunrise/sunset ramp) | DLI ~32 mol/m²/day
Environment: DIY CO2 Gel/Yeast reactor active, stable VPD and temperature control
âđ§ Substrate, Nutrition & Foliar Care
âDry Back Management: Executed a controlled ~15% dry back to enhance root zone oxygenation before the next watering.
âPenultimate Foliar Application: Performed the penultimate Vita Race foliar treatment using a fine side-spray mist strictly on fan leaves to boost foliage vigor prior to bloom.
ââď¸ Canopy Maintenance & Strategy
âSelective Central Defoliation: Plucked 3â4 large central fan leaves to open up her dense inner core and eliminate micro-humidity pockets.
âFinger Trimming: Nipped off minor shading leaf tips in high-density areas to maintain clean airflow throughout the canopy.
âNatural Structure & Stretch Plan: Currently allowing natural growth with no LST clips or stem bending applied. Awaiting the impending flowering stretch to strategically perform super cropping or apply LST clips as needed.
âđ Overall Status
âBig Demon is building a massive, compact vegetative base with no formed pre-flowers yet. The central leaf removal opened her tight core significantly. She displays vibrant green foliage with strong "praying" leaf posture under 400 PPFD.
