So I am just about finished designing my undercurrent DWC system for multiple 4x8 tents.
Parts list:
1 x 55 gallon barrel
9 x 5.3 gallon square black buckets w/ lids
15 x 1" double threaded bulkhead fitting & 15 x 1" pond hose adapters from Home Depot
3 x 1/2" double threaded bulkhead fitting & 1/2" pond hose adapters from Home Depot
1 x 320gph submersible pump
1 x 1/2" float valve
2 x commercial air pump
8 x 4" round air stone
The design is simple. The 55 gallon barrel is kept outside the tent, filled with properly PH'd fresh tap water, and is raised so it gravity feeds the controller bucket, also kept outside the tent. Reservoir is connected with a 1/2" bulkhead fitting to the controller bucket via the float valve. This is so the system always stays topped off. I chose 1/2" to ensure that the 1" fittings don't clog and overflow the buckets.
A submersible pump is set inside the controller bucket and the pump is connected to the first of 8 buckets via 1/2" bulkhead fittings and pond hose. The remaining buckets are strung in series with 1" bulkhead fittings and 1" pond hose. The water recirculates back to the control bucket every 5-7 minutes and and the entire system remains on 24/7. Air is pumped into each bucket via the 4" air stones continuously. The system is expandable to cover much larger rooms and the 55 gallon barrel/float valve combo always ensure that the water is topped off. The entire system is pumped out every two weeks and fresh water is added via the reservoir. Nutrients are added fresh every two weeks. Each tank has it's own shut off valve. An optional water chiller is added if water temps are not remaining in the optimal zone.
Pictures to be posted in the next week or so.
Thoughts?
