SupaWaw Welcome back, everyone! I'm thrilled to be starting my first grow of the year with a strain from Sweet Seeds. Diablo Rojo XL was chosen to mark the start of the season.
To germinate the seed, I soak it for 24 hours in a solution of 40 ml of water and 10 ml of hydrogen peroxide, maintaining a stabilized pH between 6 and 6.5.
After 24 hours, the seed sprouts its root, showing off its incredible vitality!
Then, it's time to plant the seed in a rockwool cube. Since temperatures in my area are still very cold, I place the seed in an LED dome with a heating mat underneath to maintain temperatures between 20 and 24 °C.
After another 24 hours, the seedling sprouts its cotyledons.

SupaWaw Glad you’re here for this week’s update! This week, I transferred the seedling to the DWC system and adjusted the pH to 5.8.
The plant is still recovering from the change in environment. The roots haven't reached the nutrient solution yet, which is slowing things down for now.
I began light feeding this week using products from Advanced Hydroponics of Holland. Temperatures are on the low side, and the relative humidity is around 65%-75%.
The first few weeks are always slow, but I expect an explosive growth spurt once the roots reach the nutrient solution and the plant settles in. I'll continue to monitor the pH level, root development, and environmental conditions, and I'll share updates as things progress.

SupaWaw Time for this week’s progress report! This week, an unexpected challenge arose that slowed things down a bit. I noticed that something was wrong with the nutrient uptake, and after checking everything, I discovered that the pH meter I was using had a faulty probe. It was giving completely inaccurate readings, which led to several days of nutrient deficiency.
As soon as I realized the problem, I switched to my backup pH meter and corrected the levels immediately. I also replaced the nutrient solution with a fresh mix.
Once the pH issue was resolved, the improvement was almost immediate. The roots have grown dramatically, spreading rapidly throughout the mesh pot and proving that the plant still has plenty of vigor. I hope this minor setback won't have too much of an impact on the overall development of the strain.
I'll be keeping a close eye on the new growth and continuing to monitor the pH carefully to avoid any more surprises. I'm looking forward to seeing how it recovers next week.

SupaWaw It's a new chapter in the growing diary! After last week's pH imbalances, the plant has resumed very solid growth, showing a rapid recovery.
This week, I cut some lower branches to improve the structure and direct energy to the top. I have also renewed the nutrient solution, slightly increasing the doses and stopping the use of root stimulator, as the root system is strong, healthy, and well developed.
The water temperature is starting to rise, but it is still within the safe range.
I will keep an eye on the structure over the next few days to decide whether to prune before flowering.

SupaWaw Another week, another exciting update in the grow diary! The plant has entered a dynamic phase, so this week's work focused on preparing her for what's coming next.
First, I refreshed the nutrient solution and slightly increased the concentration to match her growing appetite. So far, the response has been great, with the pH remaining remarkably stable throughout the week, which is always a good sign that everything is in balance.
I also pruned the plant, removing lower growth and some of the larger fan leaves to open up the structure. This should help the plant focus its energy where it matters most and improve airflow as it gets denser.
In terms of lighting, I increased the intensity to promote vegetative growth a little more before the big transition. With flowering right around the corner, I’ve added a dehumidifier to the setup to control the environment as humidity naturally rises.
Everything is lining up perfectly for the start of bloom, and the plant looks ready for the next chapter. I’m looking forward to seeing how it stretches and transforms in the coming days.

SupaWaw Hey, growers! This week, I refreshed the system by cleaning the reservoir, replacing the nutrient solution, and adjusting everything for the start of flowering. The plant has officially entered the blooming stage and is exhibiting the classic stretching behavior, so I removed some lower branches and a few fan leaves to open up the structure. I also bent a couple of the taller shoots to even out the canopy.
The humidity is under control. I increased the LED intensity for this stage, and I added a flowering booster from Advanced Hydroponics of Holland to the new mix: Natural Power Growth/Bloom Excellarator, to support the transition.
The plant is reacting well so far, building structure and transitioning into the flowering stage nicely.

SupaWaw Hey, everyone, here's a quick update!
This week, the humidity went up a bit, and the temperatures also increased, so I added an extra fan to keep the air moving. I gave the plant the last dose of vegetative nutrients before switching, and next week I'll prepare a fresh solution and introduce a low dose of Canna PK 13/14.
I also did a light defoliation to improve light penetration and help counter the rise in humidity. The strain's aroma is starting to get stronger at this point.
The plant is doing well, adapting to the changes.
See you next week!

SupaWaw Welcome back, everyone! The plant is flowering abundantly this week, and the canopy is filling out nicely.
I started adding a small dose of Canna PK 13/14 to the nutrient solution, and next week, I’ll increase the dosage one last time to promote bud development. So far, the plant is responding well, showing denser pistil formation and a stronger aroma.
The humidity remains a bit high but stable, so I added passive dehumidifiers to support the electronic dehumidifier and prevent moisture spikes. As a consequence of the warmer outdoor weather, temperatures inside the tent are rising, so I’m monitoring the heat closely and keeping the air moving.
The pH of the nutrient solution drops by about 0.2 every 24 hours. When it reaches 5.8 - 5.9, I adjust it back up to 6.2. TDS levels also creep up every 24 - 48 hours, so I add water to bring the solution back down to 1000 TDS and maintain stable EC.
Overall, the plant looks healthy and productive. I’ll continue to closely monitor the pH, TDS, temperature, and humidity, and I’ll report back after the final PK increase next week.
