I was looking for documents on how to design an environmental chamber and came across some documents that might be of interest to others. I will revisit this and try to find more but for now a start.

Yes thanks. Lots of interesting findings.

I landed here trying to learn if anyone had thoughts on this paper which associates humates with diminished thc.

Any thoughts?

Thank you. H was hoping more would put relevant papers on growing here. Some I should add also.

Different Modes of Hydrogen Peroxide Action During Seed Germination
Hydrogen peroxide was initially recognized as a toxic molecule that causes damage at different levels of cell organization and thus losses in cell viability. From the 1990s, the role of hydrogen peroxide as a signaling molecule in plants has also been discussed. The beneficial role of H2O2 as a...

Colloidal Silver for reversing females.

Silver Nanoparticles: Optical Properties
"Unaggregated silver nanoparticles will have a yellow color in solution. If the particles aggregate, the solution with appear grey."

The Effect of Size on Optical Properties
The optical properties of spherical silver nanoparticles are highly dependent on the nanoparticle diameter. The extinction spectra of 10 sizes of NanoXact Silver nanoparticles at identical mass concentrations (0.02 mg/mL) are displayed in the figure below. Smaller nanospheres primarily absorb light and have peaks near 400 nm, while larger spheres exhibit increased scattering and have peaks that broaden and shift towards longer wavelengths (known as red-shifting).

Colloidal or Ionic Silver - what is the difference?
Colloid by definition means ultrasmall particles dispersed in a continuous medium (liquid in our case) whose properties depend on the large specific surface area. Ionic by definition means atoms, that are missing an eletron, or have an extra electron. Most products advertised as “colloidal silver” contain mostly silver ions, not silver particles, so technically they are silver solutions, not silver colloids.

Visually it should be quite easy: colloid silver is represented by a yellow-to-brown colour, where the hue depends on concentration of silver and the particle size (or the age of the product respectively). Ionic silver products are transparent, the presence of silver ion can be easily verified by adding of the kitchen salt (NaCl) which results in formation of non-soluble silver chloride (AgCl represented by white turbidity). Products manufactured by electrolysis (AC, DC, high or low voltage) are typicaly ionic silver solutions, not colloids.

Biosynthesis of silver nanoparticles from glycyrrhiza glabra root extract

Colloidal silver in various stages of aggregation, (A) clear yellow sol, (B) dark yellow sol, (C) violet sol , and (D) grayish sol, as aggregation proceeds
UV–visible spectroscopy was used for quantification of silver nanoparticle synthesis.
Colloids consist mainly of large nanoparticles having nearly spherical shape particles of size 20–
30 nm. It is clear from the images (Fig. 2 and 3) that the particles in colloid are well-dispersed
with a more uniform size 20 nm.
