Germination

MAC 1 seeds don’t need fancy tricks, just a clean, controlled environment and the classic paper towel method.

🌱 Step-by-Step Germination

1. Moisten two paper towels (damp, not soaking)
2. Place seeds between the towels
3. Set them between two paper plates or inside a dark drawer, avoid sealing them in plastic
4. Maintain temp at 72–78°F
5. Wait 1–4 days for taproots to appear

Once taproots are about ½ inch long, transfer carefully into your growing medium (soil, coco, or plug).

⚠️ Important:
Sealing your seeds in an airtight container can lead to mold and rot. Always allow airflow.

Week 1: Seedling Stage

Once your MAC 1 seeds have popped and been planted, it’s time to ease them into the world. Keep things gentle; this week is all about root development and light acclimation.

🧪 What to Expect:

• Cotyledons (baby leaves) open
• First serrated leaves appear
• Roots begin spreading below the surface

🌡️ Environment:

• Temp: 72–78°F
• Humidity: 65–70% RH
• Light: 18/6 schedule, ~25% LED intensity or ~18” above canopy
• Medium: Light soil or coco, avoid rich/fertilized soil

💧 Watering Tips:

• Use a spray bottle or syringe
• Keep medium evenly moist (not soaked)
• Water around the edge of the seedling, not directly on the stem

🚫 Don’t:

• Feed nutrients yet (unless using inert medium like coco)
• Transplant or top, wait until roots are stronger

Week 2: Early Veg & First Training Steps

Your MAC 1 seedlings are now ready to stretch out and start stacking leaf sets. This is the week when things start to take shape…literally. If growth is healthy, you can begin low stress training (LST) or prepare for topping.

🌿 What to Expect:

• 3–5 sets of true leaves
• Roots expanding rapidly
• Plants gaining height and structure
• Prepping for early training

🌡️ Environment:

• Temp: 72–80°F
• Humidity: 55–65% RH
• Light: 18/6, increase LED intensity gradually
• Distance: ~16” from canopy

💧 Feed & Water:

• Begin light feeding (¼-strength veg nutrients)
• Optional: Add Cal-Mag if using LED lighting
• Water when top inch of soil is dry

✂️ Training (Optional):

• LST: Begin gently bending side branches outward
• Topping: If plant has 4+ nodes, you can top above 3rd or 4th
• Use soft plant ties and avoid breaking stems

Week 3: Veg Growth & Shaping

MAC 1 loves to bush out, and now’s the time to take advantage of that structure. By Week 3, your plant should be forming strong lateral branches and be fully ready for shaping with LST, topping (if you haven’t yet), and pruning for better airflow.

🌱 What to Expect:

• 6–8 nodes
• Thickening branches
• Noticeable vertical and horizontal growth
• Bushy canopy beginning to form

🌡️ Environment:

• Temp: 72–78°F
• Humidity: 50–60% RH
• Light: Full intensity (18/6 schedule)
• Distance: 12–16” from canopy (watch for light stress)

🌿 Training & Care:

• Continue LST to open canopy
• Light defoliation: remove inner fan leaves blocking light
• Stake or support new growth if needed
• Consider topping again if pursuing a manifold or mainline style grow

💧 Nutrients:

• Feed ½-strength veg nutrients
• Monitor pH and runoff (target: 6.0–6.5 soil, 5.8–6.2 coco)
• Add beneficial microbes or mycorrhizae for root support

Week 4: Late Veg & Pre-Flower Prep

Your MAC 1 plant is now in beast mode, roots are locked in, branches are stretching outward, and it’s time to prepare for the flip to flower. This week is all about maintaining structure and dialing in plant health before you transition to bloom.

🌿 What to Expect:

• Wide, symmetrical canopy
• Pre-flowers may start to show (especially under 18/6)
• Vigorously branching out

🌡️ Environment:

• Temp: 72–78°F
• Humidity: 45–55% RH
• Light: 18/6 schedule, full intensity
• Airflow: Strong but not blasting — keep leaves fluttering

✂️ Training & Pruning:

• Final LST adjustments to keep canopy flat
• Optional second topping if going for bushier shape
• Defoliate 10–15% of fan leaves blocking bud sites
• Check for any signs of pests or stress before flowering

💧 Feed & Water:

• Feed ¾–full strength veg nutrients
• Optional: Add silica to support stronger stems
• Water deeply but allow medium to dry slightly between feeds

Week 5: Transition to Flowering

Time to flip! This week you’ll switch your MAC 1 plant to a 12/12 light schedule to trigger flowering. Over the next several days, expect a surge of vertical growth, known as the stretch, as she shifts energy toward bud production.

🌼 What to Expect:

• Pre-flowers forming at nodes
• Pistils (white hairs) emerging
• 30–50% increase in height
• Strong aroma starting to build

💡 Light & Schedule:

• Change to 12/12 (12 hours light / 12 hours dark)
• Ensure complete darkness during dark hours — no light leaks!

🌿 Training & Care:

• Last week to perform LST adjustments
• Light defoliation if canopy is too dense
• Use plant supports if needed for stretch
• Don’t top or stress your plant at this stage

🌡️ Environment:

• Temp: 70–77°F
• Humidity: 45–50% RH
• Increase airflow and odor control, terp buildup begins!

💧 Feeding:

• Begin transition to bloom nutrients (lower nitrogen, higher P-K)
• Add flowering boosters (like kelp, amino acids, or PK 13/14)

Week 6: Early Flowering (Bud Sites Forming)

MAC 1’s floral engine is now fully engaged. This week you’ll see the first real bud site formation as white pistils cluster and calyxes begin stacking. The plant is still stretching slightly, but vertical growth will start to slow.

🌸 What to Expect:

• Bud sites forming at all major nodes
• Pistils multiplying
• Trichome production begins (very subtle)
• Stretch nearly complete

🌡️ Environment:

• Temp: 70–77°F
• Humidity: 42–48% RH
• Light: Maintain 12/12; increase intensity if needed
• Watch for signs of light burn as flowers become sensitive

💧 Feeding:

• Full bloom nutrients
• Consider adding phosphorus boosters (e.g., bat guano, bloom PK)
• Keep pH steady for optimal nutrient uptake (6.2–6.5 soil)

🌬️ Maintenance Tips:
