drip veg & RDWC flower - thoughts?

I'm moving into a new house in a week or two and have 70 sq feet to work with. I'm currently in the planning phase, but will be constructing this, or something similar as soon as I get the keys.

My area consists of a room 10' wide X 7' deep. There's already a closet that I'll be using for my veg room.



I'm considering using a drip system for sprouting, rooting, and vegging.

Here's what I envision:



I don't want to pump water directly to the tray and distribute through one of the feeder hubs because of the clutter in the tray, and I will need anywhere between 8 and 24 feeders. Adding lines to the feeder would just require siliconing in a nipple and adding a hose.

For my flowering room I want to use a RDWC system. I plan on using six 5-gallon bucket planters with a 30 gallon main reservoir. I only want to change nutes every 2-3 weeks and I figure this will give me a good buffer, plus not having to top off planters daily would be a huge plus.


So, there it is.

lighting will consist of T5's for veg and either 400 or 600 watt HPS for flower.

I'm open to discussion on possible design flaws, re-design ideas, etc.

Any ideas?
