Sput, mspaint, I can hardly wait. These are not going to be scalar, right?

LOL Oh yea, have you read the posting rules. They're a little ambiguous, but I think we're not to make hyperlinks to commercial sites unless they are of educational value.
Since we decided to go deep water I've been looking around this site and have started collecting ideas on a recirculating bubbler. Because there are so many options I think it's time to list our priorities and goals. Here's a few ideas off the top in no particular order:
Total Yield (or per sq. foot)
Yield per plant
Length of cycle (plant to harvest)
Quality (potency)
Beauty (the plants silly)
Ease of construction
Ease of use
What else Sput?
