Coco Coir Brick (Moisture)
Coco Coir bricks are an easy and economical way (a little bit goes a long way) to hydrate soil. Made by compressing the outer husk of coconuts into bricks, this miraculous natural fiber has incredible water retention -- conserving moisture and keeping the ground cool while still allowing for proper drainage.
These bricks are good to have on hand, especially as a gardening tool in the Arizona summer, and provide an optimal growing environment for seedlings and established plants.
Pricing:
Brick: $20 (Will expand to about 2.5 cubic feet)
Vermiculite (Growth Promoter)
Vermiculite is a lightweight, mica-like mineral that improves soil aeration while retaining the moisture and nutrients necessary to feed roots, cuttings, and seeds for faster growth. Like Perlite, when mixed with compost and soil it helps promote faster root growth, and gives quick anchorage to young roots.

Bag of Vermiculite: $20 (1.5 cubic feet)
