Master_weeda Hello to all the padawans and Jedi masters!
First of all, thanks to Greenhouse for allowing me to do this grow by providing me with the Greenhouse feeding and seeds.
I remind you that I am simultaneously growing 9 pots of 10 and 11 liters in a box designed for 4, and I only use the bare minimum of equipment necessary for a proper grow at the lowest possible price.
EQUIPMENT CONFIGURATION
Box 80ร80ร160
Lamp LED Lampwin 300 watts ร2
Clip fan 15 watts
Xiaomi Deerma humidifiers 5L
Hygrometer thermometer
Extractor PROFAN 107 m3/h - 100
Programmable electronic socket ร2
1 black square pot 10 liters
Greenhouse feeding enhancer
Greenhouse feeding biobloom
Greenhouse feeding biogrow
Biobizz lightmix substrate

GROW STEP BY STEP
First, I germinated my seed with the Easy Start from Royal Queen Seeds, and I am pleasantly surprised because honestly, the success rate is very high (17 seeds out of 19), easy to use, and very effective.
Once the seedling is out and about 2 or 3 centimeters tall, I gently take it and place it directly into its final pot. I recommend pots between 10 liters and 15 liters for autoflowers grown indoors.
The pot will have been previously prepared (video in diary) with 30 grams of Greenhouse feeding biobloom and 30 grams of Greenhouse feeding biogrow, which is the equivalent of 3 grams per liter of substrate.
I then place the seedling in its final pot, cover it a bit with soil, lightly compact it, and water it to keep the substrate moist, no more.
I place my 300-watt LED lamp about 90 centimeters above the seedling with a light cycle of 24/24 for a week. At the beginning of week 2, the light cycle will switch to 20/4 thanks to a timer, as this is the light cycle that offers the best yield for an autoflower.
Day 1: light watering
Day 2: light watering
Day 3: the seedling starts to become more vigorous, setting up ventilation to increase its root mass, and light watering
Day 4: watering with one and a half liters of water pH 6.3 to which I added 0.9 grams of Greenhouse feeding enhancer (thatโs 0.6 grams per liter of water)
Day 5: no special technique
Day 6: no special technique
A pleasantly calm week with no apparent problems or deficiencies.
May the force be with you!

Master_weeda Hello to all the padawans and Jedi masters
For this week 2, no techniques practiced, I just monitored that the humidity stays at a rate of 70%. I did a light watering until day 10 because transplanting the autoflowering plants into their final pots increases the risk of overwatering the substrate. ๐ค
To mitigate this risk, it's better to water with 10 or 20 centiliters of water at pH 6.3 during the first 10 days of the seedling. On day 11, I water my pot normally with a quarter of its volume in water (for a 10-liter pot, 2.5 liters) still with a pH of 6.3, I add to this water 0.6 grams of greenhouse feeding enhancer per liter of water.๐
Enhancer is a mix of humic acids, seaweed extracts, strains of Trichoderma harzianum, and Bacillus subtilis.
It increases the vitality of the plant, improves nutrient absorption, and enhances soil quality.๐
I will do a similar watering in 2 weeks

Master_weeda Hello to all the padawans and Jedi masters!
For this week, Iโm not planning any special technique, just some watering. I'm taking advantage of this relatively calm week to remind you of what I think is the best technique for watering an autoflower.
By following these simple tips, you'll achieve optimal results throughout your grow:
Cannabis is a plant that doesn't like to receive light watering continuously. It's imperative to water it in large quantities, then wait for the soil to be well dry before watering again!
To calculate the amount of water needed for each plant, follow this rule:
The volume of water to give during each watering should represent at least about a quarter of the pot's volume!!
Examples:
for a 1L pot, give 0.25L of water at each watering; for a 4L pot, give 1L of water at each watering; for a 12L pot, give 3L of water at each watering; for a 30L pot, give 7.5L of water at each watering! etc...
To give such a volume of water, it is often necessary to water in two (or even three) times, slowly and evenly over the entire surface. Place good saucers under the pots; they will fill with water that will rise into the pot by capillarity in less than a day. It is also very important to use good quality potting soil, with good water retention capacity but also ensuring good drainage (it should contain perlite, and/or coco, etc.)
You then need to wait a few days while regularly lifting the pots with your arms. When they become very light again, you can water once more!!
Indeed, since water weighs much more than soil, a pot soaked with water weighs several times the weight of a pot of a plant ready to be watered. With a little practice, you will quickly learn to lift your pots to know when a plant is thirsty.
Itโs a technique that is both very easy and very effective, and can be applied to all potted plants!
By watering this way, in general, you should water your plants every 3 to 6 days.

Master_weeda Hello to all the padawans and Jedi masters
Week 4 is going to be crucial for this young lady because I'm going to practice main-lining and LST on her. I want to clarify that main-lining is not recommended for autoflowering strains because its predefined life cycle doesn't allow it to fully recover. This will definitely impact its yield; for aesthetic reasons and limited growing space, I have no other choice. For this main-lining, I waited until day 24 and the appearance of the seventh node. Once the main-lining is done, I will practice the LST technique, which will allow me to have a more uniform canopy, thus better light penetration and consequently a better yield. You can see a video of my main-lining detailing how I proceed to perform this technique. A little reminder and explanation about this technique: Main-lining has always been a very popular technique among growers, as with simple adjustments during the first stage of growth, you guarantee yourself more than productive harvests. It involves growing the plant vertically and symmetrically to maximize light and space, which are highly sought after aspects in indoor cultivation. By guiding the branches with strings and a series of initial trims, you will establish vigorous growth patterns for your plants.
HOW TO SET UP MAIN-LINING
Starting from the seed, wait until your plant has developed at least 5 nodes. Once they are formed, trim the plant at the third node. Remove everything that has developed below the third node (I only remove the first and keep the second and third). This will form the initial Y or T shape you are looking for. Allow your plant to recover from this imposed stress for a few days before moving on to the next step.
Your plant now has two main shoots (or 4 if you keep the second node). These should be tied down with wire or string (or garden wire). This will direct the growth horizontally. Be very careful when tying the branches, do not break them. Be gentle.
Once the plant has developed a bit, you will end up with 4 main stems. You can repeat this process as many times as you wish, thus accessing larger yields. However, remember that the more you repeat this process, the longer the growth period will be. Except for autoflowering strains, as given the extra time they need, main-lining is not compatible with autoflowering varieties. Autoflowers have very fast growth cycles, and by the time the technique is implemented, half of their development will already be over. This could potentially damage the harvests and affect the yield. As soon as you have produced the desired amount of separations, it will just be a matter of time before uniform buds start to appear. A slight regular defoliation during the growth cycle will also ensure an even distribution of light and prevent your plant from wasting energy on large unnecessary leaves. Remove those leaves as soon as they start taking up too much space.

Master_weeda Hello to all the padawans and jedi masters
For this week 5, I'm finalizing my mainlining and for this, I'm removing leaves and branches from the second nodes, keeping only the nodes on the horizontal branches for aesthetic reasons and greater ease in practicing LST. I repeat the operation until I achieve the desired shape and number of colas. I limit the number of nodes because, as a reminder, this technique is not very suitable for autoflowering strains.
For more information on this technique, refer to week 4.
I regularly weigh my pot to monitor my plant's water needs.
I'm pleasantly surprised by the recovery capacity of this autoflowering strain, which handles the mainlining quite well.
Day 31: The plant's growth is vigorous; I'm letting it recover from the stress of the mainlining it has undergone. I'm just in time to finalize the shape of my plant, which will soon enter flowering.
Day 33: Watering with 2.5 liters of water at pH 6.3 to which I add 0.5ml of TopMax from Biobizz per liter of water.

Iโm keeping an eye on humidity and watering as usual. Iโm fine-tuning my LST while stressing my plant as little as possible. Iโm combining my LST with apex pinching, which will help me achieve a more uniform canopy, leading to better light penetration and consequently a better yield.
A little reminder about apex pinching:
Pinching cannabis plants
Close to apex topping in principle, this technique has several advantages, the main one being to maintain the large central bud of the plant, with maximum production and quality.
Pinching cannabis plants
Apex pinching (the top of the plant) simply involves gently pinching the stem of the top tier of the plant between your thumb and index finger until you feel the fiber crush under your fingers with a characteristic little crunch sound. If the available space on the stem of the top tier doesnโt allow you to comfortably place your fingers, you should pinch the tier below instead.
Pinching will significantly slow down the vertical growth of the plant while stimulating the development of secondary branches, thus giving the plant a bushy shape. The plant will take a few days to repair this pinching, forming a knot at that spot, and will then continue its growth normally. Pinching can then be repeated if necessary on the newly formed next tier, as well as on any secondary branches that might exceed the apex.
Pinching is therefore an excellent technique for achieving a nice uniform canopy of the sea of green type. By regularly pinching the apex of the larger plants in your space during the growth phase and at the beginning of flowering (stretch), you will easily obtain plants of uniform height in full bloom, which will facilitate cultivation and increase final production, especially if you are simultaneously growing multiple cannabis varieties.
With a bit of practice, pinching can be done as quickly as effectively. In the case of overly aggressive pinching that results in a torn apex, it will simply yield the same results as a classic topping of the apex, which wonโt be dramatic.
