eta- a 6 inch fan is no good with a 4 inch filter , the only difference u can have is a filter one size too big for ur fan not the other way round it will create too much drag, u need a 6 inch filter mate, either that or get a 5 inch fan and filter which should be fine for a 400 watt light, if ur space is not tiny u cud get away with buying a 4 inch ruck for ur 4 inch filter, hope this helps
im using cana tera plus, im doing just about everything that my mates do. i know coco a and b is for coco soil but my mates use it in cana tera and they get really good results.
the plants in the pic are 1x skunk no1 1x blue dream and the rest are ice.
