The Figures on the Double Barrel 32 XXL13
The figures that matter on this system are aeration and power. Total volume is 380 gal and power usage is 625 W. The air pump set is one 100 LPM pump and three at 80 LPM, and that is what drives the headline number in recirculating culture. Aeration runs at 0.90 LPM per gallon. Recirculation runs at 6.32 exchanges an hour, which is what 2400 GPH gives on this volume. The aeration figure is the one that gets compared against other systems. The power figure is the one an electrician needs before the room is wired.
Planning a Room Around a 32 Site RDWC System
Start with the space, because this is a commercial footprint and not a tent. The system itself occupies 11 feet 1 inch by 28 feet, or 3.38 by 8.54 metres. Plan a grow area of 18 by 34 feet around it, which allows for aisles and working room. Four rows of eight sites on forty inch centres is what fills that area. Water temperature is the thing that will decide the season. A reservoir of 400 gal is recommended alongside the system, with a chiller of one and a half to two horsepower on it. That is a real line item and it is easy to under budget. Lighting guidance from Current Culture is given as thirty two fixtures at 600W horizontally, or forty one vertically. Read that as a canopy area and a light level rather than as a fixture count, because it is written in high pressure sodium terms. An equivalent light emitting diode room would be planned on target light intensity across the canopy instead. Veg time is four to six weeks to a plant of thirty to thirty six inches before flipping. Nutrient to start is in the box, as Cultured Solutions VEG A and B. Warranty is one year, and each system is built to specification.
