Coco w/ simple nutes works great, but stopping at a simple 2 part nute leaves out Humates, Mycorrhiza, Silica, chitin, vitamins, growth enhancers like Triacontanol, etc. I'm expecting that coco can be taken further without adding additional liquids to be purchased and measured for each res fillup.
How many bottled products are you using in your regime?
Do you use Mycos / Bennies?
There's a 2015 study saying that while Mycos can survive 40 ppm P and 1.2 EC, they don't create arbuscules (the weblike network) in hydroponic solutions.
Effect of mycorrhiza and the phosphorus content in a nutrient solution on the yield and nutritional status of lettuce grown on various substrates
In our study, the limited effect of AMF (arbuscular mycorrhizal fungi) on the nutrient uptake
by plants may have stemmed from the low intensity of the formation of arbuscules
(0.25%). The low level of the intensity at which arbuscules are formed
means that there is no exchange of substances between the plant and
the fungus, which is why the nutritional status of plants does not improve.
The study doesn't expand on it, but I assume that the lack of arbuscules has to do with there being no clay for the clay-humus-complex to form, where the ends of the arbuscules opposite the root would attach. If that's the case, what can we mix with coco, and still treat the system as hydroponic?
Maybe adding Vermiculite? EWC?
For adding these, are you saying there's no point amending or dressing, and should only do Teas / store bought liquids?
Alfalfa - Triacontanol
Kelp/Seaweed - B vitamins
Crustaceans - Chitin
EWC/Mushroom - Humus
?? - Silica
Appreciate the discussion,
