the "cannabis grow lighting myths and faq" video


"you can even push a cutting with high light, as long as the other inputs are not limiting"
coinciding with "DLI" of course.

i was literally just contemplating this last night or today, ii must have glanced over this detail when i first watched it.
those infinitesimally obvious details......


you can supply them water and nutrients through the canopy if no root system, so why not?

and here this legend is saying its possible.

Professor @Utah State, inventor of Apogee instruments, I believe. PAR & ePAR, DLI, spectrum studies galore. I have given a seedling recently 300 par after transplant. The reason growing is fun, research. We all do it. Cheers Observer SSgrower
 

Bruce Bugbee has studied recirculating hydroponics since the 1980s and has used the principles to create self-sustaining ecosystems. He has focused his study of hydroponics partially on use for long-term space missions.
In his work on developing crop sustainability for long-term space missions, Bugbee additionally focuses on nutritional needs for space explorers, determining how many different crops would be needed to sustain life. He also states that gravity is needed in order for plants to grow properly.

Bugbee has worked with NASA in his research on regenerative systems and the effects of microgravity on plants. He first began working with NASA upon his arrival at Utah State University in 1981. He was a part of the team to first grow crops on the International Space Station. This work has expanded to include lettuce and radishes. Bugbee’s work with NASA also includes the development of crop growing systems for future life on the Moon and Mars in addition to in orbit or in space shuttles.

When the film The Martian was released in 2015, Bugbee supported the idea that crops could be grown on Mars using similar methods to those used in the book and movie so long as proper composting methods were utilized. He has worked on projects for Mars farming including the use of fiber optics for indoor lighting. As a part of this research, Bugbee was involved in the 2017 creation of the $15 million Space Technology Research Institute "Center for the Utilization of Biological Engineering in Space."
 
I gotta say, prior to about 12 months ago, I'd never heard of this guy, that I can recall.
Prior to about a week ago, I didn't realize what a tremendous resource this guy has been.
I'm totally impressed with this guy.
I've been going through these vids for a few days now and every now and then, he mentions something almost as a tangent to his point, those really open up a lot of answers for me.

Thank you for gathering this resource together!
 
Try Harley Smith also, this Bugbee I have watched for 1 1/2 years only myself. As led tech advanced he was front and center as he made the Epar&par test equipment Appogee. I research daily as being indoors is new to me, now almost 3 years indoors. VPD,par,pH, EC. Lot to assimilate. SSgrower

thank you, no problem, my pleasure.


Heres Bruce Bugbees' cannalab tour

 
That is a good

did not see this one here
Professer that Bruce, he works for Apooogee wow, just woke up,Lol. SSgrower
