Should you use led's or mh/ hps

Hps is much better

But will the light heat up the tubes I was thinking of covering them with Mylar

Is LED sufficient to complete an entire grow cycle?

Yes the light will heat up the tubes, it's called radiant heat. I run both LPA (low pressure) and HPA (high pressure), and I have found that the evaporative cooling I get when I atomize my nutrient solution as with HPA, works to cool the roots zone and I can run warmer water temps and consequently warmer room temps. With LPA you don't really get the evap cooling effect but more less a very humid airy environment that's drenched periodically. If you were to allow warmer temp water it would reduce your DO levels and encourage root nasties.

So a long story short..... run HID's, use mylar. If you run LED then no worries. Just pick up a 4x8 sheet of white poly foam and lay it on top of the rails and make holes for plant sites. Now you got an insulator(kinda), but you also have a reflector to bounce the light up inside the plants. This is a huge benefit to growers because the futher from the light source the less the intensity of refracted photons. Basically don't let the light rays get to far from the plants before it is reflected back onto them. Varying spectral wavelengths (colors) also vary in wavelength frequency which determines the way in which they move and how far they move.

For the lazy grower who wants to reaffirm that they aren't complete idiots, use HIDS. They like to rely on others success and methods instead of trying to understand plant botany in depth. A MH or HPS will produce but LEDS are better in my opinion, and allow the grower an oppourtunity to learn and master cultivation methods based on the individual species of plants being grown.

Led's are better? Hahahahahahahahahahahahahahahah

leds have improved a fair bit over the last few years never used them myself, from the info out there from growers that are using them
they seem to give pretty comparable performance these days albeit they do have a higher setup cost etc

Im not calling you and idiot btw. And I ment no offense, to each their own.

Heat should really not become an issue if your HIDs are properly ducted to an exhaust
