nutrient film technique

7th week of flowering and this will be last feed then a two week flush and she should be ripe :-) Struggling to get the humidity down in this tent as the plants are to big and I bought myself a humidifier and still struggling to get it down in their night time. It don't help having so much water in there with 3 tanks. I've added some canna boost accelerator today. Tank is 50ltrs as i haven't mentioned it yet
