The parabolics give a very even distribution of light over a larger area. I've found that they give a better pattern over large plants, as the light is reflected downward at a greater distance from the bulb. Works nicely over large plants, as long as you can keep the reflector a couple of feet over the crop.
Feel like I should do some cool diagram in Paint, but I don't have the chops.
I didn't notice that your hood was cooled- so you like to fly it in pretty close? Doing large plants, I've always found that things worked best if I flew the reflector a little high, to keep the plants from shading each other- but you need headroom.
I have no idea why this is sticky.I assume you understand that we have options on your time,
And we will ditch you in the harbour if we must-
But if it all works out nicely,
You\'ll get the bonus you deserve
From doctors we trust.

Rhiz is right on the even light of a parbolic works like a charm.
Take any photogram and darken a print and you will see the flat spots and hot spots of box parking light devices.
I always love things how they work and bla blabs (that just talking and no data to back it up]
I have used parabolics for a few decades and average 0.468 grams per watt day in year out. In a plant them in buckets chop to fit, bloom to harvest.
scrog is to much work and I grow with a computer and lazy.
grams / watts/months
if you have 1000 grams finished using 1000 watts / harvest every 2 months its 0.5 g/w/m:thumbsup:
You must add months as you could grow a plant for 2 years and bloom for 4 weeks and get one hell of a number. :wtf:

Go with a cool tube if you want to eliminate shady spots for growing. IF you have a way to deal with the heat and cooling.

Just to throw this out there, I've read that lumen output also has to do with distance, so if you are assuming a certain number of watts or lumens per foot, you also need to take into account the distance of the lights at the time... a 250w light might only be 100w by the time its light gets to the plants if its too far... and visca versa.
There is also a coorolation with wattages, I noted my 250W actually pulls about 450Watts and my 400W HPS pulls about 700 Actual watts, so keep this in mind when planning breakers and fuses etc...
