MANGO FROST AUTO by Atomik Systems

Atomik_water Week 1 – Early Vegetative / Seedling Stage (Day 1) 25.8.2026 Germination Success: 100% (4/4) within 57 hours. All humidity domes removed. Light: Mars Hydro FC3000 EVO running 20/4 photoperiod @ ~120–130 µmol/m²/s PPFD. Adlite supplemental bars on standby. Environment: Temp: 24–26 °C | RH: 75–80% | Target VPD: 0.6–0.8 kPa. Irrigation & Nutrients: Zero runoff / dryback period for the first 2–3 days to encourage taproot development. Pre-buffered Plagron Cocos 70/30 base. Steering: Root zone establishment phase under ATOMIK v6.0 protocol.

Atomik_water Week 2 (Veg) – Day 15 Kickoff & Substrate Steering Week 2 is officially underway! The main photo captures the entire canopy status on Day 15 (Sept 10). I will be continuously updating this entry with more notes and photos as the week unfolds. Environment & Lighting: Main Light: Mars Hydro FC3000 EVO dialed to 50% power (~362 µmol/m²/s PPFD, DLI ~26 mol/m²/day on 20/4 schedule). Supplemental Lighting: Mars Hydro Adlite Blue runs daily between 11:00 and 15:00 for a mid-day blue spectrum peak to maximize stomatal conductance and keep internodal spacing compact. Climate: Stable 26.5–26.9 °C day / 22.4 °C night. VPD dialed in at 1.0–1.1 kPa using a passive air intake from the basement buffer. Having the LED driver mounted outside the tent keeps thermal management effortless. Irrigation & Rootzone Steering (ATOMIK v6.0): Sensor-Guided Dryback: Monitored via the Mars Hydro CA59 soil sensor. Allowed moisture in the outer zone to dry back down to 5.7% Sub Hum to maximize rootzone oxygenation. Feeding: Perimeter feed applied (400 ml per plant in a 15–18 cm ring) calibrated to EC 1.20 mS/cm and pH 6.1. Sub Hum bounced back cleanly to 7.6% with zero pooling at the base. Stem Mounding: Mounded fresh moist coco around the bases of the stems to eliminate leaning, provide mechanical anchor support, and encourage adventitious root development. Canopy Status (Day 15): Vigorous vascular response: all plants showing active 45° praying leaves and flat, expanding leaf blades.
