I browsed for a little while on this topic and couldnt find the answer I was looking for... I currenty use the reptile whatever UTH's and this weekend is the start of building new homes for my balls... The enclosures I will be building are 4ft x 2ft x 18inchs and I need to know how many flex watt feet I am going to need? Right now I will be building 4 custom enclosures over the next 3-4 months pending how long it takes to put one together and Id like to just buy all the flex watt at one time... Anyone have any guesses as to how much flexwatt im going to need? I've never used the stuff before and am kinda lost as to how you hook it up and what not if you can just cut it wherever.... Anyone have any info on Flex Watt? Thank you.
