Headroom for Tall Plants

A tomato stem runs out of vertical space long before it starts fruiting.

Light Strong Enough to Fruit

Greens forgive weak light, but peppers and tomatoes simply will not set fruit.

Root Volume Per Plant

Mature vegetables need water and root space a small pod cannot hold.

Plant Count Capacity

One salad a week takes several sites, not the pair a herb unit offers.

Trellis or Stem Support

Fruiting stems fall over under their own weight without something to tie to.
