Day 9 – After the Clouds, the Sun Returns
Following a couple of cloudy, cooler days with unpredictable UK spring weather, today we’re back in business – full sunshine bathing the windowsill, and the seedling is clearly appreciating it. On day 9, she’s showing good upward momentum, with a healthy green tone and a nicely elongated, but not overly stretched, stem. The second set of serrated leaves is beginning to open up, and the seedling’s posture is strong and upright.
This morning I gave her 1 litre of clean, pH-balanced tap water. No added nutrients – the organic super soil and Biobizz All Mix are handling that just fine for now. I’m keeping to my minimal-intervention philosophy: no boosters, no chasing perfection – just observation, clean inputs, and natural sunlight.
Observations:
Although the last 48 hours brought overcast skies and some temperature swings (unmeasured near the window), the seedling remained stable – no signs of droop or stress.
Today’s sun is back in full force, with direct light from 07:00 to around 14:00, likely peaking again at ~1350 μmol/m²/s.
Still no supplemental light or artificial environment. Everything remains natural and low-effort.
Thoughts Moving Forward:
It’s always interesting to see how a young autoflower responds to dips in light and ambient temperature – they don’t have time to waste, and yet this one seems to have taken the brief grey spell in stride.
Looking ahead, if the weather holds steady, we should start to see noticeable structural development over the next few days.
She’s holding up well. Calm, steady progress – just the way I like it.
Day 11 – Holding Strong Indoors While the Outdoors Waits.
Here we are on Day 11, and the little CBD Auto 20:1 continues to develop steadily on the sunny windowsill. The first set of true leaves is broadening nicely, and the new growth in the centre is coming in with good symmetry and colour. Stem strength is improving as well, holding the plant upright with no signs of stretching or leaning – exactly what I like to see at this stage.
I’m continuing to water only with clean, pH-balanced tap water, no additives, no boosters. Just letting the super soil mix and Biobizz All Mix do their thing. This “less is more” approach seems to be paying off so far.
Weather notes:
The past few days have been moderately sunny, with occasional clouds, but the windowsill stays consistently warm – definitely warm enough to encourage strong vegetative growth. Outdoors, however, it’s a different story: cold air, unpredictable swings, and… snails. Lots of snails.
This seedling wouldn’t last a night outside right now – she’d be a gourmet treat for any passing mollusc. For now, she stays safe behind glass, soaking up the sun from dawn until early afternoon (~07:00–14:00), and building up strength for the future move outdoors – once the weather is right and the risks are low.
Final thoughts for today:
There’s something satisfying about watching a seedling thrive under low-tech, natural conditions. No grow tents, no supplemental lights – just sunlight, soil, and simple attention. She’s doing well, and the coming week should bring the next round of leaf growth and even more structure.
Slow, steady, and sun-fed – exactly how I imagined this grow would go.
Day 14 – Two Weeks Strong & Natural Salty Signs
Two weeks in, and the CBD Auto 20:1 is holding her own beautifully. After a slow and steady start on the windowsill, she’s now clearly entering a more active vegetative phase. The leaves are spreading wide, looking rich and healthy in colour, with that classic Fast Buds symmetry already taking shape. Stem structure is upright and solid, with no signs of stretching, which tells me she’s perfectly aligned with the available sunlight hours.
Watering & Environment Update:
She continues to receive pH-balanced, clean tap water only, and the pot remains well-drained and breathable thanks to the fabric construction.
Today, I noticed white patches on the fabric pot – a common and harmless sign of mineral salt deposits. This occurs when moisture evaporates through the fabric, leaving behind minerals from the water (mainly calcium and magnesium). It’s cosmetic only and doesn’t affect the plant or roots in any negative way.
Light Conditions:
After a few low-light days earlier this week (we recorded a light intensity drop down to ~30 μmol/m²/s during heavy cloud cover), today brought back that sweet UK sunshine. The plant is once again receiving its reliable 07:00–14:00 window of direct sun, which we’ve measured previously around 1350 μmol/m²/s at peak – ideal for a low-input indoor approach.
Final Thoughts:
She’s looking compact, balanced, and ready to stretch. No signs of stress, deficiency, or pest issues – and I’m really enjoying observing how this plant responds to minimal intervention in a realistic environment.
Not rushing anything, not chasing perfection – just letting nature and a well-prepped soil mix lead the way.
Next week should be an exciting one!
