A single small plant - #7 diary

INTRODUCTION - After approximately 3 years, I'm finally getting back into cultivation! This time, I'm focusing on quality over quantity, choosing to nurture just one plant in a limited space. It's all I can manage at the moment. The grow tent measures 40x40x160 and seems well-built, equipped with everything I need: an extractor running at around 100 cubic meters per hour, a 400W Viparspectra lamp (the trusty one I've always used), and a small ultrasonic dehumidifier that's always on. This time around, I want to have fun and combine my passion for electronics with my love for cannabis cultivation. So, I've set up a control system with Arduino and a 3D printer. Given that I'm still a beginner in both fields, my automated GrowBox doesn't do too much yet: 1) Automatic lamp activation 2) Automatic extractor activation (currently every 10 minutes, running for 3 minutes) 3) Monitoring internal temperature and humidity. That's all I need to get started... the bare essentials. Some future implementations I have in mind include: 1) Air quality control (CO2 sensor) 2) Soil moisture monitoring 3) MicroSD module to save data and create Excel graphs! As for nutrients, I'm sticking with AdvancedNutrients, as I've always had a good experience with their products from start to finish. I'm still deciding which cultivation techniques to use, but definitely considering LST and Topping. This is my first time growing a plant in such a confined space... I still have several doubts and uncertainties that I'll only be able to address once I begin. However, I hope not to cause any harm and improve my skills for potential future endeavors!
