Hey guys
I have recently found some time on my hands so I have taken it upon myself to finally make myself a Racking system to house my 7 Ball Pythons, Plus I would like to have some extra tubs empty for future collection expansion.

I like to do things right the first time around, and use as little materials and money as possible, to save money for expanding my collection

I currently have eight 34 Qt. Sterilite tubs (With latches) found at wal-mart. These seem to be a good size for my current snakes, all being under 800 Grams

My first question - Should I upgrade to the 41 Qt Sterilite tub, also found at wal-mart, for Adults at 1,600+ Grams?
Or will the 34 Qt. Tubs be fine for adults?
If the 34 Qt. tubs are suitable for adults then I will be making these my primary tubs for my racks, If not then I will make a rack with these 34 Qt tubs and use it in for now, and make another rack in the future for adults, and use this rack as a Quarantine rack

Second Question - I am not very good at working with wood, I am planning on taking measurements from the tubs I am using and getting shelves pre-cut somewhere, and then stacking the tubs/shelves accordingly, then using some 1x6's or something similar to hold it all together, I want the tubs to be in the shelving nice and tight.. Anyone have suggestions on the types of material i should be using or where to get them (I live in the GTA in Ontario)

Third Question - I am planning on buying a VE-300 x2 Thermostat.. Would it be safe and efficient if I had approx 16 Lengths of Flexwatt, each one of them wired separately into a power bar, each of them approx 5 feet in length?
16 Lengths is for the future, if I add a second rack with another 8 shelves.
I figure 16x5 = 80 Feet of Flexwatt and is approx 800 Watts if I am using 10W flexwatt.. The Maximum the thermostat is capable of handling is 900W
If this will not work, how can I make it work?

Honestly I will probably have more questions in the future about this home made rack, I'll keep them all on this thread

Thanks guys
