First Grow of the Season - μSetup

Lights are back at 100 W, I've being watering every 4-5 days, buds are getting fatter, to the touch are very sticky and hard as rock. Forgot this week to take some close-up photos with the flash. See ya! Anyway, after the summer, I got a new bag of coco coir and pots (5L) to avoid overwatering and the return of fungus gnats. 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. 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 3x3ft tent?
