Vinz115 Germination Date: May 12, 2025 Medium: Biobizz Light Mix in 5L pots Feeding: 4 plants on Plagron Easy Pack (Terra Grow + Power Roots) 6 plants with Biotabs mixed into the soil Light: Dimmable LED set to ~20,000 lux (25% of the 720W led pannel) Photoperiod: 18/6 Watering (May 21): 250 mL Plagron group (4 plants): 200 mL per plant with 2.5 mL/L Terra Grow. Biotabs group (6 plants): 250 mL plain water (soil was dry) Observations: All 10 seedlings are up and healthy. No stretching, strong start under good light. First feeding today (for the one that don't have BIOTABS in soil) — everything’s looking dialed in 👌

Vinz115 All 10 seedlings popped on May 12. We're entering Week 3 (including germination) and most plants are now pushing out their 3rd set of true leaves. Growth is looking healthy and even across the board. 6 plants are running on Biotabs, while the remaining 4 just received their first feeding of Plagron Grow (5.0 mL/L at 250 mL per plant). Substrate was dry before watering, and water was applied gently in a wide circle away from the stem to avoid overwatering. 💡 Environment & Light: Light intensity measured around 25,000 lux at canopy level. LEDs were slightly lowered (around 55 / 60 cm) today to increase light exposure and stay in the optimal veg range (target: 30K–35K lux over the next few days). LED is at 290W (25% power of the panel) so I'll drop it a little before increase the power, right now the distance between led and apex is around 60 cm Last veget week before 12/12 cycle ✅ Notes: Plants are showing no signs of stress, with vibrant green leaves and upright stems. Stretch is under control. So far so good! I noticed that my timers did not completely cut off the LED panel, a glow was still visible when it went out....I started to make a control panel to control the power outlets with relays and an Arduino. I can rightnow completely cut off the power to have total darkness and more precise ventilation and air circulation cycles. I also plan to expand this system to create self-regulation via a probe composed of an ESP32 and a BME 680 sensor, all of which can be controlled and monitored via the Adafruit website.
