Potting shed base options? Standard wooden base or open to the soil?

I've a potting shed which faces due south. It has a bench along the south side and I use this when I've run out of room in the greenhouse. Perhaps yours is different but the glass only comes down to halfway, the rest being wood. I wouldn't grow tomatoes in it as I they were on the bench they would run out of height. If they were on the floor it is too dark for the first 2-3 feet.

Adding glass to the vertical section too. As you say, it wouldn't be suitable in its current form.

That makes sense now!

...more sense to me too!! Perhaps you could concrete/ flagstone 3/4 and leave a border of bare earth along the glass wall.
