HoneyBlunt42 Soaked one seed in a shot glass with Simplex SeedX
Day 3
The seed sprouted a 5mm taproot. Soaked a Simplex Coco Plug with RO water mixed with 2 drops of Simplex SeedX. Used tweezers to place the seed in the center. Put it in a greenhouse made from a 1.5L plastic bottle. Made a hole in the cap for air circulation, placed it near the radiator at home in a dark, warm spot. Soaked another seed.
Day 4
The second seed bit off its own 2mm tail, which is now at the bottom of the glass. Most likely won't germinate.
Day 5
Soaked a third seed.
Day 6
The third one pushed out a 1mm taproot. The first one rose 4cm in the plug. Haven't shed the shell yet, bringing it inside to warmth at night so the young sprout doesn't freeze. The seed that bit off its tail isn't growing any further.

HoneyBlunt42 Day 10
Yesterday, on day 9, transplanted into a 1-liter basket with coco substrate (buffered with CalMag, flushed with Simplex Coco A+B mineral salt solution at 1ml/l).
The sprout stretched 2cm and shed its shell. The sprout is stunted because I didn't keep a close eye and the taproot escaped from the coco plug. It was wasting energy trying to grip and lift the stem. Now it's sitting in 1L of coco under a greenhouse dome - a cup with holes in the lid. Below, the reservoir bubbles with solution during the day.
Overall, I'm glad it survived. The two other siblings died. One bit off its own taproot 24 hours after soaking. The second showed a 1mm taproot after 24 hours and froze. These hybrids of unprecedented strength are noticeably weaker than established strains like Sour Diesel or Durban Poison, which I grew before.
I hope to raise this sprout, take some clones. Let the genetics live with me forever. Really looking forward to a strong monster with 30-35% THC.

HoneyBlunt42 My friend is struggling with the heat. Growing slowly but surely.
Only after installing the Xiaomi temperature and humidity sensor did I see on the graph that the temperature often exceeds 30°C. This is causing the slow growth.
The plant is in a grow box, which itself serves as a heater and dehumidifier for the balcony. It has a 250W HPS lamp — it heats the balcony to +20°C when it's -20°C outside.
I started opening the windows and ventilating down to +10°C so the box stays at +27°C — a good temperature for a young seedling. Humidity stays at 30-35%, so for now I'm keeping a 0.5L cup as a humidity dome over it with holes in the bottom.
A few days ago, new equipment arrived: a pH meter and TDS meter. I was mixing osmotic water with CalMag and SilicX, then mistakenly added too much acid. pH 2.6 in the solution tank — that's no joke.
I took a liter of that solution and refilled with fresh RO water with CalMag 1 ml/l. Added a liter of water with pH 2.5 and got pH 6.2 as a result. Moving forward, I'll carefully add 2 ml of pH Down at a time and measure. Goal — bring it down to 5.6. During the vegetative stage, this is a good pH level for the solution.

HoneyBlunt42 Seedling update
Watering the seedling with a spray bottle — water mixed with CalMag and Simplex Start Up, pH pre-adjusted to 6.3. The plant is coming up slowly but steadily. Keeping the heat down by opening windows — sometimes managing to hold it at +27°C. The stretch during veg is due to the high temps.

HoneyBlunt42 The seedling has stretched 1–2 cm and is slowly recovering from heat stress. Keeping a stable 26–28°C with 50% humidity isn't always easy — cooling and humidifying the tent with a 250W HPS lamp is quite a challenge.
That said, the lamp has its advantages: it heats two adjacent tents for other projects and provides a powerful light output for the mother plants, the new plant, and the rooting of 6 clones from the previous grow (Durban Poison sativa).
I'll be opening the tent more often for ventilation and misting with a spray bottle to try to speed up growth.
The larger plant next to it is doing great and handles the heat much better than the young seedling.
