The rope lights are especially cool for indoor hydro pole installations. Still, $1000 + 1$/day in electricity, it could grow let's say 100 kg of strawberries / year with that much light (that's an optimistic estimate), which would cost say 500$ to buy in a supermarket. That's not counting the cost of the rest of the installation, fertilizer etc. Could make sense at huge scale, but not for home sized installations, I think.
