RQS #3 diary - Hydroponics feminized mix

Hi! This is my third diary. I enjoyed growing in coco during #2 diary, but now i have no time to water the plats every day or once every two days, so i opted for automation. This sistem has 4 pots (11 l) and a 50+ l water/nutrients reservoir. The pump is plugged with a timer, which runs it 30 minutes every 2 hours. Twice a week i check the water level, ph and tds of the solution, which is kept above 22°C by a water heater. Since outside temperature can fall below zero, air extractor doens't work 24/7 or the temp inside the tent would be very low, so it runs only few minutes every hour... despite this is not so good for plants. This is my first time i try with ScrOG combined with Hydroponics, hope plants will grow healty! Enjoy
