tjaym Germination Week: The Journey Begins! 🚀
Strain: Milky Way F1 Automatic (Royal Queen Seeds)
Success Rate: 1/1 (100%)
Germination Time: 1.5 - 2 Days
Final Container: 15-Liter Fabric Pot
Diary Entry:
Welcome to the start of my first GrowDiary with the Milky Way F1 Automatic by Royal Queen Seeds!
For the germination phase, I used the Cannakan system combined with their own heating mat to ensure the perfect, stable temperature for the seed.
The setup worked flawlessly.
Within just 1.5 to 2 days, the seed popped open and developed a strong, healthy 1 cm taproot.
Since this is an automatic strain and I want to minimize transplant shock, I decided to plant the seedling straight into its final home: a 15-liter Geotextiel fabric pot.
The breathable fabric will ensure great root aeration and prevent root-bound issues later on.
She is now safely tucked into the soil, and I am officially waiting for her to break the surface and show her first leaves.
Exciting times ahead! Stay Tuned!

tjaym Week 1: Seedling Stage & Perfect Environment 🌿
Day of Emergence: Day 5
Light Setup: Spider Farmer SE3000 @ 40 cm distance
Light Schedule: 18/6 (560 µmol/m²/s | 36.29 DLI)
Environment: 25–27°C (Day) / 22–24°C (Night) | ~75% RH (Under dome)
Medium & pH: Plagron Lightmix | Water adjusted to pH 6.0
Height: ~3 cm at the end of the week
Diary Entry:
On day 5, the Milky Way F1 broke through the surface!
She started her life looking incredibly strong, short, and beautifully compact.
No stretching at all, just sitting perfectly upright.
By the end of the week, she reached a height of about 3 cm.
To give her the absolute best start, I placed her under a humidity dome, keeping the relative humidity at a steady 75% both day and night.
Temperatures stayed dialed in at a warm 25–27°C during the day and dropped slightly to a comfortable 22–24°C at night.
For lighting, I have the Spider Farmer SE3000 hanging at a distance of 40 cm from the plant.
Running on an 18/6 schedule, this provides a PPFD of 560 µmol/m²/s, which translates to a solid DLI of 36.29.
She seems to love this light intensity.
Regarding medium and watering: I am growing in Plagron Lightmix.
Before planting the germinated seed, I brought the soil to field capacity.
Because the Lightmix contains enough initial nutrients for the first week and I want the roots to seek out moisture, I didn't add any extra nutrients. From day 3 through day 7, I only gave plain water carefully adjusted to a pH of 6.0.
An amazing, stress-free start for this F1 hybrid!

tjaym Week 2: Steady Growth & Dialing in the VPD 📈
Environment: 27°C (Day) / 22°C (Night) | ~75% RH (Higher at night)
VPD Targets: 0.8 – 1.0 kPa (Day) / 0.4 – 0.6 kPa (Night)
Light Setup: Spider Farmer SE3000 | Ramping up +40 µmol/m²/s daily
Nutrients: 400 PPM (0.8 EC) | Plagron Roots, Alga Grow, and Power Roots/Zym
Height: ~7 cm at the end of the week
Diary Entry:
Week 2 is in the books, and she is moving along nicely!
At the start of this week, she officially outgrew the humidity dome, so it was removed.
She adjusted to the open air effortlessly and grew to a healthy 7 cm by the end of the week.
This week, my main focus was environmental control, specifically targeting the VPD (Vapor Pressure Deficit).
During the day, temperatures stayed at a steady 27°C with 75% RH, allowing me to hit a perfect daytime VPD of 0.8 to 1.0 kPa.
At night, the temperature dropped to 22°C, and without a dehumidifier running yet, the RH spiked a bit higher.
This pushed the nighttime VPD down to around 0.4 to 0.6 kPa, but she is handling it well.
For lighting, I kept the Spider Farmer SE3000 at the same height, but I started gently pushing her limits by ramping up the light intensity by 40 µmol/m²/s per day to steadily increase the DLI.
Near the end of the week, her leaves started showing a slightly lighter green hue, signaling that she had used up the light buffers in the Plagron Lightmix and was hungry for more.
I immediately introduced a light feeding schedule at 400 PPM (0.8 EC), using a mix of Plagron Roots, Grow, and Zym to kickstart root development and vegetative growth.
She is looking strong and ready for the explosive growth phase!

tjaym Week 3: Voedingsstoffen & Milieu Controle Afstemmen
Omgeving: 25–27°C (Dag) / 22–24°C (Nacht) | 70–75% RV
Voedingsstoffen: Opgestart naar 1.8 EC (Plagron Roots, Grow, Zym, Sugar.) | pH 6.0
Water geven: ~250 ml dagelijks (piek op 500 ml op één dag)
Plantgezondheid: Hersteld naar een prachtige rijke groene kleur, kort en compact
Dagboek Invoer:
We hebben Week 3 afgerond, en het was een week van het verfijnen van zowel de omgeving als haar dieet.
Ze laat nu meerdere sets echte bladeren zien terwijl ze prachtig kort, strak en compact blijft.
Aan het begin van de week zag ze er nog iets te lichtgroen uit, wat me liet zien dat ze veel meer voeding wilde dan de aanvankelijke 0.8 EC.
Gedurende de week heb ik de dosering van de voedingsstoffen geleidelijk verhoogd, uiteindelijk piekend op een stevige 1.8 EC.
Dit deed perfect zijn werk! De lichtgroene tint verdween, en ze kwam terug met een prachtige, diepe en gezonde groene kleur.
Mijn nieuwe ontvochtiger arriveerde deze week, wat een enorme game-changer was.
Terwijl de temperaturen overdag tussen de 25–27°C zaten en 's nachts tussen de 22–24°C, kon ik eindelijk de hoge luchtvochtigheidspieken 's nachts onder controle krijgen.
Het strikt rond de 70–75% RV houden, dag en nacht, heeft me in staat gesteld om de VPD veel beter te stabiliseren.
Met haar snelle worteluitbreiding en constante groei, steeg haar waterverbruik aanzienlijk.
Ik gaf haar bijna elke dag 250 ml water met pH 6.0, en op een dag met hoge transpiratie dronk ze gelukkig een volle 500 ml.
Ze drinkt, voedt en groeit als een kampioen!
