I've decided to grow my own ganja because I'm sick of dealing no good dealers. I'll just run through the list of what I have if I've missed anything important out please tell me so I can buy it. here goes - - I have 5 Dutch passion mazar fem seeds - I have 2 grow pots filled with moist (but not too wet) soil and compost mixed in - I have a Sylvania High pressure grow lamp - I have fertilizer - and finally I have a fan because I was told I need a fan, but I'm not sure what it's purpose is. could someone explain it to me. is this everything I need to get started? or do I need anything else.
