Early trichomes are clear (CBGa), mature trichomes are milky white (THCa/CBDa) and degraded trichomes are amber (CBNa).

What type of media are you using? Amended and living soils have carbon based nutrients that require life/microbes to make the nutrients available to your plants and just require water. Soilless mediums have little to no carbon based nutrients in the media so soluble liquid or powered mineralized nutrients that are immediately plant available…

Careful with that thing. 730nm will cause a similar reaction within the plant as being in the shade and cause cells to elongate. This is how branches can bend toward the light. The side of the branch facing light will have normal cells while the shaded side’s cells elongate causing a bend.

There are deep red (680nm photosystem !) and far red (700 nm photosystem II) and infrared (700-3000nm pure heat). IR is pure heat doesn’t activate any photosynthetic activity.
