ok so i have just got back from holiday and before i left my grow room was stripped back to the bare walls and everything was packed away iam going to give it a thorough clean and get ready to start again, i was having a little look at a few different things to try and upgrade my room a little and i came across some of this http://www.charlieshydro.co.uk/store/DIAMOND-MYLAR-REFLECTIVE-SHEETING-1m-x-1.4m-203.html has anyone ever used any of this and do you think it would be better than plain mylar? any advice would be appreciated
