wazighelder Three regular seeds were placed directly in the medium. All three cracked within 48–72 hours.
By day 4, all seedlings broke through the soil with strong curvature and healthy colour.
Two seedlings still carried their seed shell, which is normal and expected to fall off naturally.
Hello cuties! ^^ 💚
Environment:
• Medium is 70% Plagron Promix + 30% cactus mix, watered with SPA
• Bathroom germination at ~22–25°C
• Now moved under the LED at ≈120 PPFD and a VPD of 0.8 kPa
Very vigorous start for a tropical pure sativa hybrid. Medium is kept lightly moist, no nutrients added yet.
Plants will remain in small pots until growth stabilises, then move to 3L Air-Pots.
Humidity will be lowered gradually, and the LED intensity will increase over time.
Why this grow:
I’ve grown autos and mixed indica–sativa strains before, and this is my first true pure sativa project.
I chose ACE Seeds because I wanted something more natural, clean and classic. Honduras × Panama felt like the perfect introduction into tropical sativa growing: uplifting, clear and expressive without being overwhelmingly strong.
The end goal is to grow Congo, probably after this run.
Congo’s reputation for a clean, clear high —no mental mist, energetic, soft and warm —fits with what I enjoy most about cannabis. The strain also carries a cultural and historical dimension that fascinates me.
Everything I learn here (indoor growing, light management, stretch control, LST, VPD, nutrient timing, etc) will help me prepare for that bigger project. I’ve read Congo can be more challenging to grow, while this run is known to be much more stable thanks to the Panama F10 parent (!).

wazighelder All three Honduras × Panama seedlings were left alone for the weekend, without extra watering. Humidity in the tent stayed high enough, and when I came back all three were standing upright, healthy and fresh. Great start. ^^
No stretch issues, cotyledons open, first serrated leaves expanding nicely.
So far: very uniform growth and zero signs of stress —exactly what I hoped for. Just a great result after seven days since sowing. ^^
Week 1 Summary Daily Parameters
Day | Height | Environment | Light | Water | Feed
Day 1 | 1 cm | 21°C / % ?RH (VPD 0.8) | 120 PPFD / ? cm | no | –
Day 4 | 7 cm | 22°C / 70% RH (VPD 0.8) | 150 PPFD / 65 cm | yes | Great White / Mycorrhizae
Day 5 | 8 cm | 23°C / 73% RH (VPD 0.72) | 150 PPFD / 65 cm | no | –
Day 6 | 8 cm | 23°C / 74% RH (VPD 0.72) | 180 PPFD / 55 cm | no | –
In the coming days / weeks I expect to:
- Start Plagron feeding once the root system is properly established.
- Increase light intensity gradually (targeting ~250+ PPFD).
- Lower RH step-by-step as the seedlings get stronger.
- Keep watering slow and minimal.
- Transplant into 3L Air-Pots when the second or third leaf sets are fully open — safer to do later rather than sooner.
- Manage the fact that I'm working in a small 60×60 tent with limited height, which will definitely be a challenge with a tropical sativa.
Any ACE sativa tips are welcome —especially for managing stretch in a small tent. :)
ACE sativa growers: tips for controlling stretch (Honduras × Panama) in a 60×60?
Tent is only 160 cm (~120 usable), so space is very limited.
Planning light training/topping —how do you keep these in check?
I have 3 seedlings but will keep only 1.
To keep it small, keep it horizontal
Flip early 2–3 weeks from sprout. Don’t veg long
Small pot 5–12 L to keep her from turning into a vine tower
Top once at the 4th–5th node, then LST everything sideways. Anytime a branch points up bend it back down
Run the plant like a flat disc not a christmas tree
If needed add a low SCROG 25–30 cm and weave during stretch
Keep light intensity moderate during the first 2 weeks of flower to reduce internode spacing
Do that and she’ll stay around 80–110 cm and fit your tent without drama 👊👍
One can take clones and flower them shortly after they establish roots which will keep them small. Another thing you can do is give them lots of darkness through photoperiodic control, which often (not always) results in shorter internodal spacing and wider plants. One way is give them 12 hours DLI but interrupt the scotoperiod with an hour of light in the middle to keep them in vegetative growth. Alternatively, give them 14 hours DLI. But... In your case the clone hack would be better. This gives you adult plants ready to flower but more the size you decide on.
With 120 cm useable space... a safe guideline would to be to flower plants no taller than 40 cm. They can easily double or triple in size when changed to flowering light schedule.
