G-Rex™ - 1 gal

G-Rex™ is custom blended in Northern California, never dried or dehydrated. G-Rex is formulated to be used throughout the entire growth cycle. It will continue to work from the rooted cutting stage all the way until harvest. When making cuttings, add G-Rex as soon as root nodule forms at the base of the cutting. For example, when you set up a tray of rockwool or clone plugs, water with HumTea®, wait seven days and then water in G-Rex™. After transplant, continue to use G-Rex™ in your system at the recommended rates through harvest. G-rex™ is compatible with any fertilizer program, however G-Rex™ is developed for use with Cutting Edge Solutions® fertilizers.
