Hey Prawn, i got a thread up your alley but i couldnt tag you. Check the midpower section for bridgelux new uv pump chip, thrive, similar to optisolis. I dont really have the chops to evaluate them, maybe youd want a look. But bridgelux are usually a bit cheaper than nichia so there might be a point to look into them.Prawn Connery wrote: ↑Tue Jun 25, 2019 10:20 amI tend to agree. There's a lot of guess-work out there and very limited studies into cannabinoid production - some if it contradictory. It would seem the more you can "fill in the gaps" - as with natural sunlight - the more chance there is of not missing something, even if we don't fully understand it.Rocket Soul wrote: ↑Tue Jun 25, 2019 8:01 amLol, i can see im preaching to the choir. Im pretty sure its that study i was talking about but i dont quite recognize the format. I sat down a month or so ago and just had a good read on several studies but sometimes im a bit sloppy and i dont quite remember. I had something with smaller print (of course my brain works like the smaller the print the more scientific and valuable the information ;p )
My whole point was that nature seems to reuse its ideas and functions in life: light therapy in humans is focused on 660nm and far red which seems to be the most potent, same as in plants. If it opens the stomata its bound to do something else aswell, or at least its an educated guess until we actually know different. Personally i think rather than pinpointing frequencies like a scalpel there might be a point making sure nothing is missing: broad blue/uv spread without it getting too much to draw down yield too much. Cmh has served us really well, seems like they allways outdo their on paper spec, and they feature this broad sunlike spectrum, from uv to ir. But it wont beat our best led yields but im not sure if this has more to do with light distribution which bulbs arent that good for. But cmh sure makes for an easy, no finicky grow, almost on autopilot in comparison to led.
Having said that, there are things we know that work in terms of yield and plant health that apply to a broad range of species, such as red light driving plant mass and excess blue light impacting yield, so there are still some basic guidelines we can use as we continue to make new discoveries.
Now i will try to not clogg the growoff thread anymore but this discussion on spectrum is really interesting. OG, please let us know if you want us to take content to another thread before it bothers you its nice to see such a positive attitude for a change and i dont wanna step on anyones feet
