Day 4. The res temps are stable at 72. Ph is stable at 6.1. The nutes are slowly rising ad the res drops, but I will not go over 800 ppm's. So different from hps/promix rooms, where we let the nutes go to 1200 ppm. growth rate is phenomenal. Roots are coming down the drain tubes. I have pruned off any low nodes, and TOH will be putting the screen on in a few days. We are doing deathstar in promix, under 1000 watt hps, and the led/aero room is far more vigorous. The plants look turgid, but in the best way. The fan leaves are huge, unlike they have ever been in the old school rooms. Omg, I love aero!!!!
