Cuor Di Bue,
We grow tomatoes through plastic that's black underneath, white on top. The black suppresses the weeds, the white reflects the light back up to the plants.
Drip irrigation tape in place under the plastic.
that's about as high tech as it gets around here.
These firm fleshy toms are the best sliced thickly with basil....over 4kg of which, was harvested the morn...mmmmm
