Same grow box, same LED, same water tank — the only difference is the planting deck you choose.

	15-hole deck	67-hole deck
Best for	Full-size leafy greens and herbs — lettuce, basil, bok choy, kale	Raising seedlings, and narrow-stemmed plants — spring onions, chives
Plant spacing	Wide — room for plants to reach full size	Dense — many small plants at once
Typical use	Sow, grow and harvest mature plants in the box	Start seedlings here, then transplant to your tower or garden — or grow slim herbs to harvest
Harvest style	Fewer, bigger plants	Many small, quick harvests
The box itself	Identical — full-spectrum LED, self-watering tank, same footprint	Identical

Not sure? Most home growers start with the 15-hole deck. Choose the 67-hole if you mainly want to raise seedlings for a bigger system.
