great white is endo mycos and trichoderma, and a few other species. IMHO the concentrations are very low. they have a 260,000 spore/gram count and we have 5 billion (18,000x more concentrated). The reason the nute pack (mycorrhizae), and root pack (trichoderma, bacillus, etc..) are separate is because mycorrhizae are unecessary and potentially harmful in a pure hydro setting.
Seagreen is a very good product. It is also bennies. Only drawback is that it smells kind of shity... but it is a great product nonetheless.Made by a guy who really knows what the fuck he is doing.
Your plant line up looks awesome BTW.
The packs are a supplement to your existing program. The only thing they are meant to replace are other supplements (great white, azos, mykos, voodoo, tarantula, etc).. basically any other beneficial bacteria/fungi innoculant on the market. Also the foliar pack is designed as a non-chemical way to treat insects like RA's, fungus gnats, mites, thrips, caterpillars, harmful nematodes, aphids, grubs, etc.. and also powdery mildew.
Combined with Aliens program and a-1 nutes organic line, you should be able to produce some outstanding pesticide/fungicide free fruit.
This is at best a guess.A1's Humic Fulvic blows it out of the water, as long as you got colonized Mychorizze or Caps in full affect you wont need either of those products.
