Out of curiosity, how did you do the internal cabling?

Heavy duty 20mm conduit is tough, but not easily sealed & requires a
drain hole at the lowest point. HiTuf & IP68 cable glands seem to make
best use of IP56-65 rated sockets/lights/switches (ie, maintain IP
rating).


I used 20mm plastic conduit with shallow bends for going through 90
degrees. For the obtuse angles, I warmed lengths of conduit and bent
it around a slightly undersized curved former. On cooling, it
springs back slightly. Joints were made with solvent welding.

conduit runs were arranged to accomodate low points with drain holes.





HiTuf may not be as tough as heavy duty conduit.

Probably not, but would probably be adequate unless one is going to
swing a spade around.


SWA seems either overkill or difficult to install in greenhouses/
sheds.

Both.
