Window Box Planters

We have two choices for the box planters that are readily available at Home Depot/Lowes:

1. 24" L x 5.5" H x (7.5"/4.5" tapered) W
2. 30" L x 5.5" H x (7.5"/4.5" tapered) W

Around the outside is a slight lip (~.5") where the edges are curled under.

Given the plant spacing (5 cm apart) we can fit 36 plants in the smaller one and 45 plants in the larger one. The disadvantage to using the larger one is that it seems rather long, and may be problematic when transferring during the flight. I feel like the 24" would be best. Dr. Zhou's idea earlier was to plant them in pots in 3 x 3 rows, and use 3 or 4 pots at a time. This setup would yield 36 plants at a time, so the 24" planter would accomplish this. If Dr. Zhou feels we need more plants, we can just strap on a second planter or use the 30".

The price for the 24" planter was $6.23 ea, and for the 36" planter was $6.73 ea.

Let me know if you see problems with this, or have any other ideas that would work better.
