gamberro Welcome to my microgrowing project! This is actually my second grow attempt. My first one was outdoors, but sadly the plant didn’t survive while I was away on vacation. This time, I’m taking things indoors with a completely different approach: ultra-limited space, maximum automation, and plenty of enthusiasm. Setup: - Grow space: 35x48x52 cm (yep, almost impossible – it’s originally a clone tent). - Pot: 4-gallon fabric pot cut down to around 5 liters, bonsai-style. The idea is to keep the plant lower and avoid it getting too close to the light, since vertical space is super limited. - Automation: everything is controlled via Home Assistant + OpenGrowBox project . Humidity, climate, and ventilation are all automated as much as possible. Strain: - Gorilla Z Auto (FastBuds) – a strong and popular autoflower. It was a gift from my grow. Germination: I started on Day 1 with the classic paper towel method. Within a couple of days, the seed cracked, showing a healthy white taproot. On Day 3, 48 hours from the germination date, I prepared the soil by moistening it with 100 ml of water, then transplanted the seed into its final pot. To maintain high humidity, I used a cut plastic bottle as a mini greenhouse. Progress: - Day 1: seed placed in paper towel. - Day 3: taproot emerging strong, transplanted into soil after moistening with 100 ml. - Day 4: first sprout breaking through the surface. Grower’s Notes: - The space is ridiculously small, but it's the space that I have, which makes this a fun challenge. - I’m very curious to see how FastBuds genetics will perform in such a restricted setup. It will need a lot of LST. - This will basically be an experiment in extreme microgrowing, trying to make the most out of minimal resources.

gamberro This week marked the very beginning of the journey. On September 11th, the seedling received its very first watering: 50 ml with 0.1 ml of Acti·Vera by BioBizz, to encourage healthy root development and reduce early stress. A few days later, on Sunday the 14th, I repeated the same dose with another 50 ml. Everything is being monitored through OpenGrowBox, and so far I’m really happy with the automation – it keeps the main parameters under control and makes things much easier. When it comes to watering, I still feel a bit uncertain: I’m giving small amounts because I don’t want to overdo it, but the substrate stays evenly moist, which tells me the plant is getting what it needs. The pictures show the seedling evolving day by day: cotyledons opened strong, and within a couple of days the first set of true leaves appeared. The stem stretched a little, which is common in the early stage, but overall she looks healthy, with a nice green color and no signs of stress. A promising start – the plant is settling well and ready to take off. Day by Day – Week 1 Day 1 (Sep 11 – evening) First watering after germination: 50 ml with 0.1 ml Acti·Vera (BioBizz). Cotyledons recently opened. Day 2 The seedling is standing up straight, cotyledons are fully extended. Still small but looking healthy. Day 3–4 The very first pair of true leaves starts to emerge. Stem elongates a bit as she reaches for the light. Day 5 (Sep 14 – morning) Second watering: 50 ml with 0.1 ml Acti·Vera (BioBizz). Leaves show a nice green color, no signs of stress. Day 6 True leaves grow larger, stem looks a little stretched but strong. Substrate stays evenly moist. Day 7 The seedling is settling nicely, developing the second set of true leaves. Healthy start to the journey!

gamberro The seedling looks healthy this week, with a nice green color and good symmetry. The stem is still thin but standing strong, which is normal at this stage. The third set of true leaves is coming in and growth is progressing steadily. The soil looks well-aerated with good drainage, no signs of overwatering. Environment seems stable thanks to the fan and climate control. Overall, she’s reacting well to the root stimulators and starting to build momentum for faster growth in the upcoming week. Watering & Nutrients - Day 8: 150ml of water with Acti-Vera (0.12ml) and Root-Juice (0.22ml). - Day 10: 150ml with the same mix of Acti-Vera + Root-Juice. - Day 14: 100ml of plain water.

gamberrostarted grow question 12d ago
I’m wondering if this is the right moment to do a top cut (apical pruning). Should I wait a bit longer, or is it fine to do it now? Also, is it okay to top a FastBuds autoflower, or is it too risky? I’m dealing with some space limitations, only 52cm of vertical space. Thanks

gamberro This week the girl kept developing nicely — she’s looking stronger and bushier every day. The leaves are a healthy green and she seems to be enjoying the environment so far. On Sunday night I noticed the first signs of pre-flowering: a few little white hairs started showing, which means she’s already switching gears into the next stage. Exciting moment! You can see them clearly in the close-up shots. On Monday I started some light LST (low stress training). The main reason is because of my limited grow space — she’s showing a very bushy structure, and I could already see that light wasn’t reaching the lower leaves properly. By bending her down I’m hoping to improve light penetration and open up the canopy. So far she has reacted well, no stress signs. Watering has been consistent, around 200 ml each time, with nutrients added: - Sep 25 (Day 17, Week 3): Acti-Vera (0.1 ml), Bio-Grow (0.2 ml), Root-Juice (0.4 ml) in 200 ml water. - Sep 29 (Day 22, Week 4): Top-Max (0.2 ml), Bio-Grow (0.4 ml), Bio-Bloom (0.2 ml) in 200 ml water. So far she’s reacting really well to the feeding schedule — no signs of burn or deficiencies. Another thing that makes this grow so smooth is the OpenGrowBox project. Everything is super automated: it keeps perfect control of temperature, humidity and VPD, turning on and off the fans, extractors and humidifier exactly when needed. Honestly, I barely have to keep an eye on her — OpenGrowBox does the job really well and I’m really happy with how it works. The structure is coming along nicely, and thanks to the LST I’m confident she will spread out with a better canopy for the upcoming weeks.

First time trying LST. I have very limited space and my plant is getting bushy, so I used garden wire + clips to bend her down (see pics). Not sure if I did it right. Any tips or corrections are welcome!

You want an anchor at base of plant tied to opposite side -- this prevents the plant from pulling/damaging its roots. It may look fine today, but resistance over time can pull it through the substrate. Training is simply about manipulating apical dominance. Tallest growth tip on more primary branch will take the most resources and grow the fastest. LST is attempting to spread that strongest growth out across more than 1 branch. The more level you make it, the more even the growth distribution will be... Growth may not be perfectly even, initially, but you can further manipulate it by temporary tying the taller branches lower than the shorter ones and it will even out quickly. Release when even. to get a more horizontal bend, try bending in 2-3 spots close together... don't need to damage vascular tissue, so don't do this to the point of feeling it get squishy or anything like that... just creating multiple points in stem that help it create a near-90-degree bend. Now is the time to tie it down with the anchor in place and the bend if mostly formed on its own. The tie-down can pull it down the last little bit to level it out. you usually get too many branches with LST. So, i'd bend it 'on a growth axis' so 1 is pointing up and symmetrical growth is pointing down.. .prune off branches facing down. You can always bend down between growth axes and now you have 2 branches at a 45-degree angle that can both easily grow upward, but like i said, usually don't nee dso many branches emenating from a small stretch of trunk. Also, have a plan. you want 2.5-3 colas per sq ft... divide that by number of plants.. and you know how many colas you want per plant... don't waste time overcrowding beyond that. once you have the right number of vertical or future vertical branches, even it out and let it go. Easy to apply to any size area and any number of plants... just be systematic and it'll save you time, money and effort. Cutting off a bunch of growth is just wasting your money and time. find a path that reaches end goal of canopy with least amount of waste.
