The shop, explained
Four by Four
16 positions · 5 L each
The Four by Four is the larger stack: four quad planters, sixteen five-litre positions, sixteen of the eighteen catalogue varieties in the box. Dill and pea have treatises; they are not in this kit. Same soil-and-open-seeds system as the Three by Four. Three by Four is the beginner kit.
The kit
Four stacked quads. Sixteen five-litre positions. Sixteen of the eighteen catalogue varieties ship in the box. Dill and pea have treatises; they are not in this kit.
Sixteen of eighteen
Sixteen packs: sixteen of the eighteen catalogue varieties. Dill and pea have treatises; they are not in this kit. Same open-seed doctrine. Same one-saucer stack. Same 5 L position. Fertiliser and Halo remain separate Range pages.
The larger start
Sixteen positions are still a courtyard or a wide sill, not a smallholding. They are the larger start of the same practice as the Three by Four: leaves and herbs you stop buying because you cut them here. The planter is still the pot.
