Not to sure if this is the right place but here we go anyway

Up the garden I have a fridge freezer in my summerhouse and a shed behind it which is properly insulated except for the roof. in the sheds my growtent and in that im planning to put a 400 hps. do you think it will look like the fridge and freezer does to a chopper in the sky if it happened to be browseing, and would you insulate the roof. now its a fairly big roof so i was thinking of just insulateing the bit dirrectly above the tent.

what do you rekon

I would get a piece of 4" kingspan and put it over the full inside of the roof, just to be safe, although I don't think 1 x 400W would give much of a show.

Spliffter

i Will look into that just to be safe

2inch will easily be enough and loads cheaper

i have just done my first grow. in a fridge in my shed i used a 125w cfl not a lot of heat given out off the bulb so no expensive insulation
