Now, keep in mind I didn't get to design these rooms from the ground up (I took the project over mid way through the first run due to some issues) so I basically used what was there (like submersible pumps, 2×4 stands for the trays, 1×1 for the trellis poles....) to keep costs to a minimum
Reservoirs have 2- 3/4 HP Coleman submersible pumps. Each pump runs half the garden (10 heads, 36 sprayers) with large filters with 120 or 80 micron filters (need to check the box)

Both 1" drops come into the room and run straight to the back while T-ing off to each tray

The runs are two tables each with an 8 drop floraflex "octobubbler" feeding each tray

As you can see I run the 1" PVC past the last head and also past the last T's going to the tables to help equalize pressure as much as possible

The runoff comes out the end of the trays to a 3/4" PVC line that I run to a collection bucket which has a sump pump with a float inside

The pump in the runoff collection bucket is the pumped into a marked barrel so I can measure volume of daily runoff

These are the 360° sprayheads I use in all my pots. The stay super clean and are under 40 cents a piece when ordered in bulk
