Finding a water tank

I can't think of anything commercial that would use something that size. The

Any good?

How about a water carrier of the sort used by campers - poly bottle basically with large filling cap and tap on front face.

AWEM

A made to measure fish tank (fairly easy DIY)?

Or just knock something up from plywood, and put a layer of glass cloth and resin on the inside to proof it.

Or gets some styrene sheet and cement, and make one.

Or solder one up from tinplate, copper or brass..the number of fuel tanks for model planes one could get out of a Colman's mustard tin was amazing..

Also try Tupperware boxes...may find something suitable

Also various guttering bits may be usable..a standard hopper with the middle cut out and glued back together maybe..

But given that it's long, deep and narrow, I think making it from scratch is the most sensible approach.

Model railway suppliers will do you styrene sheet that you can cut with scissors and glue wit styrene cement.

Thank you all for the suggestions. I particularly like the idea of buying something bigger and cutting the middle out - obvious in retrospect but it never occured to me.

This sounds easy too - only question is whether the glue or styrene cement might leach toxins into the water that could upset my plants.

well polystyrene is used a lot in plant propagation, so I doubt its harmful The cement is just the plastic dissolved in a solvent and that evaporates after making you high and giving you a headache.

Polystyrene dies IIRC degrade in sunlight over time though. UV etc.

Sealing the take-off tap in isn't so trivial. Very do-able, but the camping water-bag is easier, to my mind. (I use a different water-carrier in my camping kit, but I recognise the ones described. Very effective.)

Or tent fabric and make your own water-bag, as per original suggestion. Still going to be fun getting the valve to fit tightly.

silicone is good.
