Interesting project.

Your idea sounds similar to how strawberries and other small vegetable crops are grown in some areas in the US using what is referred to as "plasti-culture". Its a combination of plastic sheets covering the soil (below soil root warmth), fertigation (water and nutrition), and possibly low poly-tunnels (above soil leaf and stem warmth/protection).

You don't have a risk that plants will die so its more of solution of getting an earlier crop and better prices. This is exactly why the plastic culture/fertigation thing came along.

If incremental revenue is greater than incremental costs than why not try it but that's a calculation that you will need to make based on your local input costs, resources, and revenue opportunities.

Let us know what you do and how it turns out. Very interesting.

Good luck!
