Wanted to post this in case anyone was interested in a easy way (albeit expensive) to build a recirculating DWC. I'm going to journal the first grow using this system.
The Ebb and Grow system in place has been used for 2 previous grows, but I decided to use this space to experiment with something new.
Maybe a couple people here might remember me for my post on the HydroHut death syndrome back in 2007. Maybe not. Either way here are some pics...
The plants were vegged in 3-part GH nutes in 4-inch cubes with a flood table downstairs. They were transplanted into the recirculating DWC system upstairs yesterday.
The Lights - 4 digital lumitek 1000 watts with "Ocho" xxxl hoods
Cooling - 1 10 inch maxfan pushing air through the lights and out of the room
- One 12,000 btu window ac, and one 10,000 ac downstairs pumped into the upstairs flowing room
The reason I liked the idea of this system is the way it accomplishes recirculation with DWC. Most other systems using a water pump to constantly circulate water through all the plant sites. This has the following downsides:
--- if the roots clog any part of the hose, the system will flood everywhere.
---adding nutes can't be done at once, otherwise roots will be burned
---adding h202 can't be done at once either
---adding nutes requires waiting until solution is equally distributed into the system
With this system, the brain bucket is told to keep the buckets flooding all the time, except for one 30 minute interval at night time.
When the system is told to drain at night, all the buckets flood back into my 105 gallon rez, thus "recirculating" all the buckets. Any time I want to add nutrients or PH adjuster or h202 during the day, the system will automatically evenly disperse it into the system during the nighttime "drain" period
