The SLG Troubleshooting Chart functions as the organizing tool for the program. You will be using a new chart every time you do the program and you will be doing a lot of writing on it. There are 50 loose-leaf, 3-hole punched blank charts per pack.
A blank chart is printed in the Soil-less Garden Companion.
