I will say on this topic.. The faster you can get your mycos or root better in my case is always the best.. The faster they can start attaching thereself to the Roots and begin the better.. I know since we are on the topic of roots and mycos that P at above I believe 50 ppms can put them to sleep..
@Ecompost will be able to back me up and help on this topic with mycos and roots..
Major benefits I have already seen from Root better or Mycos in general..
Plant resistance to drought.. When I transplant them into pots I really let them dry so those roots expand the most possible. SO by second watering with my mycos and letting them dry out they are filling pots at an alarming rate.. No extra's besides root better and the basic k-amino I am using..
Huge fuzzy white roots--- I am not lieing when I say I thick beautiful roots.. I will be sharing photographs of my roots when they dry up a bit more to get a good photograph..
Not only that with mycos/Root Better you don't have to have high p levels or nutrient levels.. They do great at nutrient uptake.. Really is amazing things I am seeing and learning..
Previously I have tested on synthetic side
Rootz Excelerator-H&G
Rhizo Blast-
Botanicare
Black Label Roots-- Can't remember exact name
All expensive as can be..
By far Root Better has shown me those most amazing results in root growth and they are so pretty.. LOL
So
Root Better results so far
