Cut-and-come-again
Why spinach?
Spinach matures in three to four weeks and does not need replanting after every cut. Take the outer leaves, leave the core growing, and the same plant keeps producing.
The case for it
Four reasons this crop pays for the tower.
Multiple harvests per planting
Cut the outer leaves and let the core run. Continuous yield with minimal downtime between cuts.
3–4 week cycle
Among the fastest crops in the system, with a steady year-round market behind it.
Free of soil-borne disease
Downy mildew and fusarium wilt live in soil. A soil-free system removes the vector entirely.
Longer shelf life
Clean harvesting and no soil contamination mean the leaf holds its colour and crispness longer in transit.
Who buys it
Your buyers are already looking for this.
Grocery, juice bars, frozen and prepared-food manufacturers, restaurants.
What they all have in common is that they need it every week — not in a glut in August and not at all in February. Consistent supply is the thing you are actually selling them, and a controlled system is how you promise it with a straight face.
