Very well put! EXCELLENT posting! Rep+ to you!
I have been gathering the equipment for a "far red" nm range experiment for about a month. My partner is in the process of building "LED light bars" to put on one of our 1k Raptor hoods and run this exp. in an 8'x10' "tall plant" area with "light mover". The LED's will be 6' and one on each side of the hood. The light mover is a "high speed" model and has been doing a bang-up job in this area (closed off) of the grow. We have made another area exactly the same on the other end of the grow for a "control".
The idea of the LED "evening" light came from my looking at induction lighting. The Inda-Gro companies add-on 420-PFR-PONTOON system got me interested in this concept. At about $750 USD, I found it to be one of those overpriced grow deals geared to the "I'll try anything to be better" crowd. My partner, further more saw that he could build a set to our needs for far less and set about the task. He studied what the needs would be and began obtaining the needed materials. The project is almost complete at this writing!
I'm still interested in the Induction idea, it's just that for our size an investment of over 17k is not quite what we have in mind at this time. I am watching the threads here on how well this system works.
Your last post brings this PFR thing to the masses here always looking to "get better". What I'm trying to do with this experiment is find out if this will.
Increase quality
Decrease run time
Save on cost as a result
I have found there to be a possible correlation to shorter internode spacing and some what heavier yields in the use of PFR addition by another long time grower in the area. Problem was he did no "control" testing and has Inda-GRO lighting system with the PFR pontoons over his complete but much smaller grow. Yet the early indications from him are promising!
I expect to implement this in the 2nd quarter rotation. If interested, I can supply a very preliminary result at the end of that rotation. To be sure of the results we are going to run this experiment for 3 rotations, with differing strains, both in active and control area's.
Great posting Cannacove!
