Five-pot expansion kit for The Urban Farm 5-Granite.

It's easy to expand your Granite Series 5-pot Urban Farm to a 10-pot system. Kit includes:

-5 x 4gal Granitized grow containers.
-5 grow basket inserts.
-tubing harness to make connections.
-float extension for reservoir level control.

Rockwool is not included in the expansion kit.

(the reason we don't include rockwool is because it's most likely that when expanding to a 10-pot Urban Farm, you will probably want fresh rockwool for all your pots, not just five)
