I’m building our a 1600 sq ft grow room and have been to the moon and back with many vendors on plans and schematics for everything from electrical to irrigation. I did a forum search and didn’t return any threads but maybe those of us who’ve been down the ‘build out’ road can compile a thread of information on recommendations, various setups and pricing ranges for irrigation/fertigation methods for the community?
I haven’t pulled the trigger yet but for the 1600sq ft room, I’m outlining x6 4ftx32ft tables with x8 4x4ft LED lighting footprints above each and 6 plants per light. That delivers the below specs:
-Plant Count = 288
-Light Count = 48
-Amperage used on 220v fixtures = 140A
-Lights per 20A breaker (2.9A each 220v fixture) = 5
-x2 36,000 BTU minisplits ($8,000 equipment + install)
A couple questions:
-Does anyone have a solution to warm water inline before it gets to fertigation so I can come straight out of the well without housing reservoirs in-house? I don’t think there’s a heater capable of hitting the target GPM flow required to feed 144 plants (1/2 the room at a time) with starting water temp of 43 degrees.
-Who has knowledge on reservoirs, pumps, gpm, dosatron irrigation and fertigation?
