How often do you give your plants mycorrhizae? I dust my roots during transplant and will even sprinkle some on the seeds, but after that I do it here and there. Bottle says every feeding, but of course they are going to say that.
For soil and Coco Coir I use Tribus and then recharge every 2 weeks as a root drench. In water I do a Azos and kelp root drench from the top and this grow I am using Lumina and Tribus in the res and it is kicking ass.
I am trying a new one by TPS called Billions. No humic acid and uggghhh no molasses . When I was growing autos the first time TPS sent me some info on this but had not hit the market yet. They sent me one free so i am going to try it and let them know how I like it. Nice people there. I know they have it out on the market now. I am use to using Recharge every other week. I have not used anything else except fish shit and I threw the little bit I had away. I just did not see a difference like I did with recharge. JMO
I rub a tiny dose of great white on the peat pod I use to germinate. Then I put 1/4 of a scoop in the nutrient solution at growth phase changes after a fresh water flush. I can look at my roots, so If I don't see a lot of side "fingers", I might give a tiny sprinkle during veg.
