These are my flowering lights. Although vegging plants and yes even my seedlings have absolutely loved this spectrum. Is this at all similar to what you refer to? What would you increase or decrease in terms of spectrum. Because this one has grown like no other light I've ever used. HLG seems to be having some issues lately and I've been hearing about delays and delivery issue so i'm concerned and readying to search out new lights in the future.

The one thing i do like about this spectrum is that its relatively low green- in all our tests green was associated to loss of "in your face" smells to something more mellow, (maybe even complex?) for example: Rainbow Chips under our better spectrums had a very clear fruity/mint loud nose and chocolate taste (well, you could taste the chocolate if you eat some to bring out the taste). Very much a dispensary/smoke club profile, like and stand out go to kinda of smell.
In the higher green spectrum, even with added uv, this turned into some kinda spicy lavender (maybe even licorice? Im not that good at smells and flavas) kinda thing - not bad but not the kinda thing 9/10 would go for.
The plant green response which can be summed up as intracannopy/structural response. The one part of a plant or tree where green is prevalent is deeper into the cannopy, behind a bunch of leaves. It can be summed up as:
- reversing of the blue response, meaning:
- inhibiting transpiration
- reversing blues effect of shortening of node spacing.
Morphologically:
Green recruits plant resources to grow thicker denser fibrous tissue, the kind of tissue needed for sturdy branching - it grows stick

(and very likely higher abundance of leaves though this is more my own observation rather than based on science papers, possibly also due to high blue content in most modern growleds).
Personally I dont think anyone is growing weed to get more stick, were all in for fragrant juicy bud. Sending resources towards stick and fiber is not going to do any favors for smells and taste department.
