First Grow of the Season - μSetup

Maximizing these last weeks of flowering getting closer with the lamp so that the two Special Queen #1, that are shorter than the Black Jack CBD, would get the last ray of "sun" even if that means that the Black Jack CBD is going to "suffer" and foxtail a bit. Some trichomes are starting to get amber. Buds on the Black Jack CBD are still much emptier than the other two girls. 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?
