Bernd_Bonaparte Great news—my Banana Kush seed has popped and is standing tall! 🎉 Tiny cotyledons are already showing a healthy green, and I’m excited to watch this girl take off over the next few days. Here’s to a strong start! #BananaKush #Seedling #GrowDiaries
**Day 5 – Seedling Update**
Great news: all three Banana Kush seedlings are settling into veg! 🌱
The cotyledons look bright and healthy, and each plant has its first true leaf set. They did stretch a touch at the start, but the lowered light and steady airflow should help them thicken up fast.

### Environment
* **Temp / RH:** 25 °C day – 21 °C night / **75 % RH**
* **Light:** LED at 35 %, now **20 cm** above the canopy, 18/6 schedule
* **Airflow:** Two fans have been running unfortunatley only since yesterday to keep fresh air moving and strengthen the stems
* **Medium:** Light mix with extra perlite in 0.5 L peat pots on a seed-heat mat
### Watering & Feed
* Still giving only **plain Gerolsteiner Naturell** (pH ≈ 6.2 out of the bottle) – no nutrients yet; runoff looks clean.
### Observations
* Stems are a little lanky from the earlier light distance, but colour is good and the new growth looks happy.
* Roots should start circling the peat pots soon; a gentle tug already shows light resistance.
### Next Moves
1. **Up-pot in 3–4 days** into 3 L Air-Pots and bury an extra couple of centimetres of stem to fix the stretch.
2. Keep RH around 70–75 % for another week, then start lowering to ~60 % as they bulk up.
3. Gradually ramp the light to 40–45 % once they’re settled in the new pots.
So far, so sweet—here’s hoping for chunky Banana Kush colas down the road! 🍌✨

Bernd_Bonaparte Big picture: two Banana Kush girls are back on track after the “swamp-soil” episode.
Day What happened Take-aways
7 Transplanted all three into 3 L Air-Pots; culled the runt (planned). Found the mix soaking—lesson learned: water less!
8-10 Zero watering to let the new pots dry and roots breathe. Pots felt light again by the end of Day 10.
11 First drink since transplant – plain Gerolsteiner (≈ pH 6.2), ~250 ml per pot, tiny runoff. Both seedlings perked up quickly; colour deepening.
Current setup
Temp: 24 °C day / 21 °C night
RH: 70 – 75 %
Light: LED 35 % @ 20 cm (18/6) – will gradually raise intensity over the coming week.
Airflow: two small fans running 24 h
Plant health
New growth looks clean and turgid; internodes tightening since the light was lowered.
No feed, no top-dress, no Cal-Mag planned yet—just letting the roots colonise the fresh medium.
Next week
Keep monitoring pot weight; water only when the upper layer is dry and pots feel ~30 % lighter.
Bump the light to ~40 % in small steps if the leaves keep praying.
Stay the course with plain water until the plants ask for more.
Wrapping up: the week started soggy but ends with two happy Banana Kush seedlings ready to hit real veg growth. Onward and upward! 🌱💪

Bernd_Bonaparte Both Banana Kush girls are settling nicely into their 3 L Air-Pots. Temps / RH stay around 25 °C / 74 %, LED 40 % at 30 cm, plain water only. Growth is steady and the 5th node is showing—thinking about topping soon but still undecided. Pics show their current size and shape. 🌱

Bernd_Bonaparte **Veg Week 3 (Day 15 → 21)**
* Avg temp **26.4 °C**, RH **72 %**
* Still in the 3 L Air-Pots – transplant is on hold for ~4 days while I wait for the missing centre-lid on the FlexiPot air-base.

### What went down
| Day
| Action
| Result
|
| ------ | --------------------------------------- | -------------------------------------- |
| **15** | **Topped above the 4th node**
| Two new mains visible within 48 h
|
| 16-17 | LED 35 % → **40 %** (20 cm height)
| Leaves lightly praying, no stress
|
| 18-19 | 350 ml plain Gerolsteiner, light runoff | Pots dry in ±48 h – roots filling fast |
| 20-21 | Snipped a couple of big fan leaves
| Centre opened up, bushier profile
|
---
### Current status
* Mid-green colour, no nutes yet.
* Slightly root-bound; stems thickening nicely.
* No heat issues despite the warmer tent.
---
### Next up
1. Water sparingly until the FlexiPot base arrives.
2. **Up-pot** & give a first light veg feed (~0.6 EC) the same day.
3. Start gentle LST on the two new mains.
Girls are charging ahead—just need their bigger homes. 🌱💪

Bernd_Bonaparte Week 4 – Recap & assessment (Day 22 → 28)
Key events: late arrival of the FlexiPot AirBase → transplant was pushed back; finally up-potted, then applied a first round of low-stress-training (white branch clips).
Stress factors: three unplanned “dry” days right after the move, extractor down for a while, temps spiked to an avg 29 °C – one plant shows clear drought/heat stress (yellowing lowers, slight claw).
Outlook: roots should rebound fast now that moisture is back. Trim any fully yellow fan leaves, keep the medium evenly moist (not wet), and consider a mild, N-heavy veg feed next watering to replace what was sucked from the lowers. Aim to pull temps back to ≤ 27 °C and RH 65-70 % for smoother VPD.
