I use great white, its a mix of mychorrhizae and beneficial bacteria. Plants love it, and come harvest when i check the roots i can see the webs of fungi knitted into the roots. Id say its worth giving a go

I ask as I've had the mycorrhizae down for awhile now and it's looking pretty good but I can't find a lot of discussion about adding Trichoderma after the mycorrhizae is established. I noticed a couple studies mentioning exactly that but was hoping some members have some first hand experience they can share. I'd like to add it to help prevent any fungal diseases in the future. Cheers.

Okay sounds great. Since posting I've added the tricoderma and see no issues.

They co exist in different parts of the roots and rhizosphere, it decreases the abundance of myco, but allows easier colonization by it.
Some plants benefit more from applying one first, then colonizing the second, but dual application works. You only need to put it on once to get the benefits of priming the SA and JA repsonses in a plant.
Trichoderma spp. also compete with other plant beneficial microbes and impact the arbuscular mycorrhizal fungi (AMF) abundance in bulk soil
microbiomes in agricultural systems. In this sense, a single application of T. harzianum increased the rhizosphere levels and facilitated the access of AMF to the roots of the host (e.g., wheat) and non-host (e.g., rapeseed, Arabidopsis) plants.
Trichoderma spp. can also act as indirect biocontrol agents by activating systemic immune responses in a coordinated way, resulting in faster and stronger induction of plant basal resistance mechanisms upon the perception of a later triggering stimulus. This phenomenon is known as priming of defence and Trichoderma can provide the plant with long-lasting resistance
Trichoderma harzianum favours the access of arbuscular mycorrhizal fungi to non-host Brassicaceae roots and increases plant productivity - PMC
The family Brassicaceae includes plants that are non-host for arbuscular mycorrhizal fungi (AMF) such as the model plant Arabidopsis thaliana (arabidopsis) and the economically important crop plant Brassica napus (rapeseed). It is well known that ...

As biotrophic fungi, Trichoderma and AMF are sensitive to SA-dependent defenses which prevent the fungus from entering into the vascular system. During the early stages of the interaction, the establishment of a symbiotic relation requires the suppression of SA-dependent defense responses in the plant, which are compensated by an increase of JA-/ET-regulated defenses. The alternation of SA- and JA-dependent defense responses leads to an undulating defensive response in the plant once the fungal colonizer has achieved an effective root colonization.

i use both and both have extra root hormons and stuff. soo i do mycos as soon as there is roots touching the water and then 2-3 weeks later one more time. then 2-3 weeks after that trich .

I had better success doing myco that way too, using Bassiana or LalStop46 later, instead of trich.
Bassiana plays well with myco, LalStop46 was much more aggressive with myco, just use it for outdoor foliar innoculation now.
