First Grow of the Season - μSetup

Now at 90 w from the wall at 800 par. Flipped the lights 12/12 on the 21st of October, at 500-600 PAR at 75 W. Week 9 (and a half) 1 week of flowering, stopped stretching, going to bend some taller branches to level it out. Stretching is more prominent on the Black Jack CBD. Going a bit heavy with the feeding. Next week I'm going with the recommended dose + some Cal Mag. So, after the summer, I got a new bag of coco coir and pots (5L) to avoid overwatering and the return of the little shits. Same setup as always though, the μSetup (micro), the keyword: efficiency. The Tent is a Zelsius 40x40x120 cm, substrate is Wilma Cocolite, light is Mars Hydro TS1000 dimmed down and the nutes are Terra Aquatica TriPart. Anyway, now I wait for the flower stretch hoping it won't be too much of a hustle. I'm probably going to have problems with watering, humidity and light penetration but still, I wanted to maximize the productivity, I always thought that growing on bigger tents was easier but too inefficient, I don't know, will I regret ditching the 3x3 ft tent?
