What is the cheapest way to heat those sterilite 34qtz?

i think i'll go for the flex watt, i just find those heat mat (zilla and zoo med type) pretty expensive... thanks everyone!

I agree, you can order 5 heat pads and clips and wire it up for the same price as 1 zoo-med or equivalent pad.
Flexwatt is def the way to go IMO
