I have a few photoperiod feminized seeds in solo cups that are at their second to third node. When watching Mr. Grow Its video series on transplanting I saw him sprinkle Mycorrhizae in and around the hole created for the plant to be transplanted into. I purchased some Great White Premium Mycorrhizae and the instructions for soil say to dilute the powder in water.
Is it manditory to dilute it in water or can I just sprinkle in and around the transplant hole before placing the plant in her new home?
