setting

G'day guys, just a question about nutrient levels. First time growing in doors, used to just put seeds in with the vegies and just water in but growing now medically for personal use. I bought an EC metre and was told on setting mS that it should be reading 1.9 , just wondering what all this...

Hi All, great site!! I'm setting up my first grow tent ,it's 31cf I have a 1000w led on order ,I just want to know what CFM inline fan to get for Carbon filter to suit this size tent . Cheers Kev
