The seeds got planted today.
First, the 11L (3gal) fabric pots are filled with BioBizz Lightmix. Because of the lack of definitive information about this, I have estimated that this soil has approximately 10% perlite in it. Therefore, I have added an extra 5% perlite and 10% vermiculite. After adding all substrates together, it is poured over in a large bucket with lid and tumbled to mix everything. When mixed, I added 50gr Biotabs Startrex and tumbled it some more until everything was thoroughly mixed. After which it is put back in the fabric pot. This process is repeated for all 3 pots separately.
Back in the pots all three received 1L of a Bactrex (1gr/L) and Orgatrex (10ml/L) solution. After watering with the solution, the soil compacted a little, so I added ~3 hands of Lightmix to the top and mixed it a bit with the top layer.
After waiting a few hours to let everything set, I have added 2 Biotabs fertiliser tablets, on opposing sides, to each pot.
A hole, of ~10cm wide and ~5cm deep, is made in the middle and 4gr of Mycotrex is sprinkled in. After which the hole was carefully closed again. A new smaller hole (~1cm diameter) is made in the middle in which the remaining 1gr Mycotrex was sprinkled and the Royal Critical auto seed is planted. A little bit of soil is carefully put over the seed, sprayed moist and a clear cup put over it.
The third pot went through the exact same process but, due to not having enough Mycotrex, RQS easy roots Mycorrhiza was used with the same quantities.
2 out of 4 lamps are turned on, on a 24h schedule at a height of ~90cm. The extraction fan and oscillating fan are turned off for now.

All three pots received a thermal pad (5W) under them at 50% power.
Each pot received a few sprays of water on the seed location, to keep the soil moist.
10/12/2025
Sprayed the top layer of each pot with water until moist.
Plant #1 and #2 are showing fungal filaments on the top soil under the cup, indicating that the Mycotrex successfully inoculated.
Carefully removed a bit of soil, to check if the seeds have germinated (I'm impatient). All three seeds appear to have germinated successfully. Although seed #1 and #2 appear to be a bit to deep in the soil. Unfortunately, I can't fix it any more since they both have taken root.
After I was done, I carefully, and loosely, put a bit of soil back on top of the seeds.

Plant #3 officially sprouted today. The seed shell and membrane was still on the plant, so I helped it out carefully with a rounded tweezer.
It appears that I have put too much soil back on top of seed #1 and #2. Because of this the plants appear to have trouble finding the top and are growing downwards a little. To help them out a bit I have removed most of the soil that was on top to let the light penetrate a bit better. This way the plants have a guiding star to find their way out.

#3 is looking very healthy and appears to have had a great start. Sprayed it with a bit of water and made sure no big droplets formed.
#1 and #2 are slowly making their way out of the soil.
13/12/2025
#1 and #2 have finally sprouted. Both still had their seed shell and membrane still on, so I helped them out a little.
#3 is looking very healthy and growing happily.

#1 and #2 are recovering well and both look healthy.
#3 is growing nicely and is almost 5cm tall.

Put some styrofoam under the heating pads.
Soil temperature is, after a few hours, ~23C at a depth of ~10cm.

Plant #3 received 100ml of tap water around the edge of the pot, to promote root growth. This plant is growing well, the second set of leaves is already visible.

Plant #1 and #2 received 100ml of tap water around the edge of the pot, to promote root growth.
After some closer inspection, it appears that plant #1 has a burst stem (hypocotyl). After asking my fellow growers on this platform (see my grow-question), this is probably because of the humidity domes causing a too high humidity. The plant looks healthy otherwise, but a little smaller than the others.
Removed the cups from the plants.

All 3 plants received Biotabs BoomBoom spray. A 100ml solution (5ml/L) was mixed, with which all the leaves where sprayed dripping wet, top and bottom, just after lights on. After only a few hours there was actually a notable difference in the leaf colour. Since these plants don't have that much leaf surface to spray, I used the rest on other house plants and they appeared to be enjoying it as well.
Raised the growing lights to ~80cm from the top of the highest plant (#3). Also turned on the oscillating fan, to increase air quality and strengthen the stems of the young plants (with indirect airflow).

Moved the oscillating fan to the other side of the tent (diagonally), to blow over all three plants more equally.
The signs of overwatering are disappearing and the plants appear to be recovering well.
23/12/2025
Plant #1 and #2 received 250ml of tap water and #3 received 300ml.
Put the oscillating fan on a timer, with 30min on and 30min off.
27/12/2025
Plant #3 received 500ml, #2 received 300ml and #1 received 250ml of tap water.
All three plants look healthy but, #2 and #3 seem a little small, and #1 is noticeably behind. This is probably due to the colder environment and the plants being slightly overwatered in the beginning.

Plant #2 and #3 received 500ml, and #1 received 400ml of tap water.
Plant #3 has started to produce a very faint, but very typical, cannabis smell.

All three plants look healthy, but all are too small, especially Plant #1 is quite a lot behind in development, though its stem has healed nicely. I hope they will still grow out a bit in the coming weeks.

I've decided to give the plants some Biotabs BoomBoom Spray, to help them out a bit.
All three plants got their leaves (top&bottom) sprayed with the solution (5ml/L), until dripping wet.
enjoy your royal critical grow- what happened to the little stem?
i have never seen something- i dont think its because of your humidity domes-
looks like they got some injurie by handling them
@Mia_BIOTABS, Thank you!
Not sure what the cause was, but I was extra careful not to touch the plants before this, so I think I didn't damage the plant directly.
Fortunately, the plant seems to be recovering well. The wound is already closing and becoming more hardened.
