Si is a non-essential element that confers increased vigor and resistance to plants in response to numerous environmental constraints. Its use in agricultural practices could therefore be considered to improve the biomass yield of economically important cultivated plants, such as fibre crops. Our preliminary results indeed show a positive effect on hemp primed with Si, as well as a protective effect against Cd toxicity. However, to date, only a handful of studies are available concerning the impact of Si application on the growth and differentiation of fibre crops. In the future, the use of biophysical tools (e.g., micro particle-induced X ray emission, X-ray absorption near edge structure) for the elemental analysis of accumulated Si should be considered to map its distribution in different tissues, in connection with high-throughput transcriptomics and/or targeted gene expression of key candidates (cell wall-related, for example), as well as the quantification of phytohormones in stem tissues.​

Specific to hemp as fiber crop, but it definitely doesn’t seem to indicate anywhere in the paper that hemp is an Si excluder, does it? Maybe I don’t understand...yep, I didn’t understand those terms properly.

I've been told by many professionals- plant scientists with degrees, that is- that if one can get information about the response of tomatoes to given inputs, it's a pretty good stand in for cannabis.

I've used Si foliar sprays to control powdery mildew and as a nutrient, mixed with other foliar ingredients.

I never saw any noticeable difference between using it and not.

That's just me and my conditions may be different from those of others.

It doesn't seem to hurt...

There are plants in soil, rockwool, and coco in that tent, they are all on the same reservoir that runs at about pH 7.2 most of the time. They seem pretty healthy to me. If people try to tell you there is one ideal pH range for soil and another for hydro, please refer them to me. It is not always the case. For anyone doing chemical fertigation, the nutrients’ specific formulations are the another factor in the equation. All you organic living supersoil zealots already know everything, surely, so you can disregard this post.

JR Peters Labs claims the base soluble fertilizer I am using allows uptake of all nutrients up to pH 8.0 and I believe it. I think the plants prefer 6.8 but they do fine at 7.2-7.6, so far.
Does anyone else screw around with pH? My experience is that people stress about pH far too much, not only in growing, but the aquarium hobby too. It is important, but not as static or critical as people make it to be.

Hey, whatever happened to @Cold$moke ? You around, dude?

Did you have any problems with the rockwool, looking at a blumat setup using rockwool, but have been told to rather use coco. Some feedback from you would be much appreciated, thanks in advance
