BCN Critical XXL Autoflower

Okay soo this is my first proper set up grow. I Will be using 2 x 450W Viparspectra LED panels. Only one panel is being used now, but ill set up the second one during the second week! Im growing 3 Seedstockers BCN Critical XXL Autoflower. Ive heard good reviews about this fast growing strain. Hope i get good yields for them. They say it grows around 70-75 days from seed in good environments. Im using BioBizz Lightmix soil. I will be using Biobizz nutrients too but on small doses. The plants will be in 8 litre pots (6 litres filled). Ive got a 5” RVK with Rhino Pro filter, and a cheap 5” inline fan for the intake. Im just missing a fan controller for the perfect environment. Also got a 5 litre Humidifier, with a controllable stat. Dehumidifier is soon to arrive in the mail. Ive also added MYKOS Root Enchancher at the third day around the plant. Ive got given this by my local hydroponic store as a freebie. Apparently its a organic fungal root enchancher. Its better to be mixed with the soil around 1-2 teaspoons per pot.
