Sorry tty I don't really get it. Why reinvent the wheel? If you can do one and pull down over 2 lb a light then I am all ears. I am not trying to be rude, and I am sure it is coming off that way. Just don't see the point. You ask for a #, 2lb. People can and do make this happen with horizontal set-up. Assuming that is the point of the build.
Also not sure why bother with the reflectors? Anyone who has grow herb knows the light level under the canopy/behind in this case, is not enough to give and additional yeild. For the cost of materials to build a mover would you better served to purchase a 600?
Hey, brother! Long time no see! Hope all is well with you and yours-
So the basic question of why for me boils down to an engineering exercise; can the job of growing high quality cannabis be done with less inputs? The answer is always, ' yes', the question becomes one of how.
To drill down into the specifics of this approach; first, there is no reflector on the light at all. It moves vertically about 4 feet, up and down a column that is trellised to be full of plant material. I'll place a bit of reflective material at the top and bottom of the cylinder, but that's there to help the bud at the very top and bottom edges get sufficient light.
The bulb is always very close to the trellis, and even closer to buds growing out towards it, hence the need to move the bulb. Moving the bulb also has benefits for reducing light shading. Most approaches utilizing moving lights aim to just spread light around a bit and stop there. By contrast, my strategy is to use one to get the bulb so close- and therefore provide so much light- that it has to keep moving to avoid burning the plants. This is a strategy to maximize the plant usable DLI, beyond that which the plants could take continuously.
If I believed I would only get 2 from one bulb in this setup, I too would be wondering, 'why bother?' However, I'm aiming for three on my first run, and perhaps four once I really learn the ins and outs of this approach.
Isn't the promise of doubling your output per watt and per Sq ft attractive? If this- or any- investigation reveals insights into how to ply our craft better or more efficiently, isn't that worthwhile?
For you, a strain that's 'good enough' really represents a jumping off point in the quest to find or breed something better. That's how I feel, looking at the current state of the art in indoor growing equipment today.
