First Grow of the Season - μSetup

I'm back! Had to take a break because of summer and its temps. Turns out I had a big fungus gnats infestation in an old stock of coco coir, I tried to "sterilize" it (on the 2nd diary, RIP that too) but it didn't work. 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. Seeds germinated on water and paper towel the 26 of August. I popped a third one two weeks later because i thought i couldn't fill the tent (big mistake). 18 hours a day with light at 300 PAR, 40 W from the wall. Flipped the lights 12/12 on the 21 October, now at 500-600 PAR at 75 W. I learnt a lot of things in this grow like that too little nutes is almost bad as too much nutes, I tought it was less relevant, but no, better watch the color of the leaves instead of the PPMs. 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 selling the 1x1m tent?
