Ye im not going to do anything rash unless im 100% sure its safe.i was running an extension lead from the downstairs socket up through the platerboard but i dont want the family seeing this. wot do u mean by a 'heavy extn lead' i was using a normal extendable roll up one. if i call in a sparks, chances are he's gonna know its a growrrom (its already set up apart from a few minor things). i have a friend who studied mechatronic engineering so maybe he'll know what to do.

what do u think of my oscillating fan-flexihose idea for intake?
