You can't do that.

It has to be either wire with a coating rated for direct burial, or you have to dig a trench and run conduit.

I'm a to-code fanatic... sorry...

This just seems like the most overcomplicated idea ever for how little space you will be afforded.

If I were going to do an underground grow, it would be with an excavator and a steel shipping container... a REAL growroom that I could walk around in comfortably.
