The point of myco is establish a root mass that is 10,000 times bigger with the addition of the fungia absorbing nutes and passing them to the plant. Also keeps the plant healthy.
I had success using hydrogaurd with hydro.
However myco in soil messes with ph and must be compsenated for. This is acceptable for the gain.
It is no big deal and bacteria make it swing the other way so in organics there is a balance.
In hydro it seems the roots already are exposed a huge amount on their own.
I now use gh three part with the hardwater micro and straight tapwater undechlorinated at all.
I am having great results. I use hydro h202 and superthrive in addition. White roots so far.
I dont want to introduce all that living variable into this hydro system as it might mess with the chelates and buffers.
In soil i say organic. In hydro I say chem for now. I am not a dan of ro water and cal mag right now.
I think I am lazy, however after looking at results between chen and organic hydro many times I was plain grossed out looking at the plants in organic next to mineral systems.
The organic kinda looked sickly topside.
IDK, before h202 I used hydroguard, which is myco by botanicare for a good price. It is meant for hydro too.
Howver I have seen some awesome pics of hydro myco mj plants. Prob used botanicare or other organic nutes. Some of these need a partial water soil food web I guess you could call it to get the full benfit.
