GreenHobbit Week 0 – The Start of a New Adventure 🌱
While my Laughing Buddha starts its flowering in the 120×120 tent, the next project is already kicking off in the heating cellar.
This time, I want to document three extraordinary autoflowering genetics independently. Each plant will have its own diary, so we can track their development week by week.
Kicking things off is the Auto Malawi × Northern Lights from ACE Seeds.
Why this strain in particular?
ACE Seeds has an excellent reputation among lovers of sativa-dominant genetics. The combination of the legendary Malawi and the tried-and-true Northern Lights immediately piqued my interest. I'm curious to see how the strength, vitality, and structure of this cross will develop.
My goal is to let the plant grow with as little intervention as possible and to learn about its natural characteristics.
The Setup
The three autos are growing together in a 70 × 70 cm tent in the heating cellar.
For the seedling phase, I'm using a Secret Jardin 26 W. With the help of a PPFD sensor, I measured the lamp accurately for the first time and set it to a distance of 25 cm. This gives the seedlings around 160 µmol/m²/s – a value that is ideal for the first few days.
At the moment, they are growing in 0.5-liter pots. As soon as the new 15-liter fabric pots arrive, they will be moved to their final containers.
Germination
The germination went smoothly.
The Auto Malawi × Northern Lights was the first of the three plants to show its taproot and then broke through the soil surface first. A successful start to this new project.
Current Status
The cotyledons have already opened, and the plant looks healthy, compact, and vigorous.
Thanks to the optimized light intensity and high humidity during the germination phase, the conditions for a strong start are looking very good.
I'm looking forward to following the development of this exciting genetics in the coming weeks.
See you next week! 🍀

GreenHobbit 🌱 Auto Malawi × Northern Lights – Week 1
The first week is done, and the Auto Malawi × Northern Lights is making exactly the impression I hoped for.
It was the first to germinate, the first with roots at the bottom of the pot, and it's currently taking the lead above ground as well. After moving from the small seedling pot to its 15-liter final pot, it has continued to grow without any pause. This is exactly how you want a start to go.
At the beginning of the week, I removed the humidity domes. The humidity in the tent is consistently between 60 and over 80% even without the domes, so it no longer needed that extra moisture. Shortly after, I swapped the small Secret Jardin LEDs for the Spider Farmer SE3000. Right now, it's running at 20% power at about 40 cm distance. After noticing some slight light tips on the leaves, I cautiously raised the lamp a few centimeters higher. Since then, it has stopped growing taller and is visibly investing its energy into its leaves.
I particularly like the leaf shape already. For such a young plant, the first true leaves already look a bit longer and narrower. Maybe I'm imagining it, but the Malawi influence seems to be showing slowly.
The journey is starting promisingly, and I'm looking forward to seeing what this African genetics will reveal in the coming weeks.
There was a €25 voucher from zamnesia because they revamped their site. I immediately ordered new 15l fabric pots with it. @zamnesia, thank you very much for that! ☺️

GreenHobbit 🇲🇼 Auto Malawi × Northern Lights – Week 2
The second week is done, and the Auto Malawi × Northern Lights is developing just as I hoped. Already, it shows impressive growth vigor and seems to be the most vital of the three plants.
The stem has gained significant strength in just a few days, and the internodes remain pleasantly short. After I raised the lamp about 3 cm a few days ago, there have been no further signs of light stress. The slightly burned leaf tips from the beginning of the week are practically irrelevant now, and the new growth is completely healthy.
The strong branching is particularly noticeable. Even now, well-defined side shoots are forming at each node, suggesting a bushy structure. The leaf color is a rich green and uniform, indicating that the soil is currently providing the plant excellently.
For week 3, I expect a significant growth spurt. If it maintains this pace, it should quickly become the largest plant in the tent.

GreenHobbit Auto Malawi × Northern Lights — Week 3
Week 3 – The Stretch Begins
The Auto Malawi × Northern Lights was once again the strongest plant in the tent this week.
At the beginning of the week, it already showed a very stable and even structure with short internodal spacing, a strong main stem, and well-developed side branches. The small damage to some leaf tips from the previous week has not progressed, and all the new growth looks healthy.
Throughout the week, its growth has changed significantly. The internodes are starting to stretch, and especially in the last few days, it has gained quite a bit of height. At the same time, strong side branches are developing at practically all nodes, so despite the increasing vertical growth, it maintains a nice branching structure.
By the end of the third week, it is clear that the plant is slowly transitioning from pure vegetative growth to the next phase. More and more new growth points are emerging at the top and on the side branches, and the first signs of pre-flowering are becoming visible.
Since the nutrient reserves in the soil are likely running low after three weeks, I have supplemented with Green House Feeding as planned. The plant has shown no negative reaction to this. The leaf color remains healthy and even, without burnt tips or noticeably dark green.
Currently, I am still letting it grow completely naturally and skipping training. It will be particularly exciting to see how strong the Malawi influence comes through during the stretch.
Very strong third week – and now it seems like it really wants to take off. 💚
@Xonidan I know that. From the 5 autos from the last grow, Blueberry and Hyperion are my favorites. The others are not bad either, but they're just not really my first choice 😅
@GreenHobbit, I want 3 nice plants that won't outgrow the tent and won't take forever. I'm going to top once. Above the 2nd node or the 3rd, and in that case, remove the lowest one.
