Hi there I'm a newbie to the whole grow tent thing and it's cost me an arm and a leg-im making rookie mistakes like I couldn't afford vermiculite and the other draining one- I've germinated my LA Amnesia seeds very well. One has 4 small leaves and the other looks like its a gunner.....its really scary and their like my babies. I thought I was over watering so I've cut it down to once a day-18 hrs of light 4hrs darkness even though their autoflowering. When do you put in the ventilation system and ducting/fan? I feel their too small-makes me feel like crying like a proper girl-yeah yeah I know I am a girl but this is daunting-any help welcome. Ps I've canna coco soil mixed with compost high in phosphorous with bone meal and rose feed mixed into it
