I have two oscillating fans on opposite sides of my tent. No matter what I did, it seemed like the fans were always facing right at each other. I kept trying to unplug one to get it to run opposing cycles. I need the air to circulate, not just meet in the middle.
I finnaly figured out that one fan has to be running faster than the other. That kept the wind swirling instead of just pushing back and forth. It seems to be pimp now. Just my .02.
Now I'll read the rest of your post above sorry.
Makes sense, thanks - maybe I'll just run one fan at "3" and one at "1", or something like that - need to get the tent setup sooner rather then later, been kinda dragging my feet on that.
For anyone interested, crunched some numbers regarding horizontal vs. vertical, and they're below:
The Coliseum Growing System is 67" wide by 93" tall.
Using those dimensions for a flat grow (comes to 43.3 square feet), and using a baseline watts/square foot of 62.5 (2 1Ks covering an 8x4 area), it would require 2700 watts to light that footprint. For simplicity's sake, we'll call it 45 feet and 3000 watts, just to work with round numbers.
Still with me? Good.....
So, the full-sized Coliseum is designed to be operated with 3000 watts.
Using that same footprint, the Coliseum has an effective growing square footage of 185 square feet, or more then 4X as much as a horizontal garden (I crunched these numbers myself, but the formula for the surface area of a cyllinder is [(2*pi*r^2)+(2*pi*r*h)] for anyone who'd like to double-check me).
So, instead of a 7x7 footprint (round numbers, the equivalent of 45 square feet), that 3000 watts is now effectively covering a 14x14 footprint!!!
And if anything, the canopy management is easier with a vertical, because EVERY plant is equidistant from the light source, and generally closer to the light source then they would be in a flat garden.
Add in the fact of close to 0% of the light being wasted, and it just makes sense.
The only downside, IMO, is the DIY aspect that I'm going to have to perform (and the plant counts, but I'm gonna be over 100 plants no matter what I do), but I think I can handle it - just building a wooden frame and then glueing some PVC together. The real issue is gonna be the design work, but I'm confident in myself.
Even though the startup time and effort is probably going to be enormous, this just makes too much mathematical sense for my brain to not do it.
Soooooooooooo.....................anyone have any quick and dirty tutorials for using Google Sketchup?
