so what you say about the plant starving if it only gets what is in the bucket is essentially saying that a rdwc system would help with feeding and such to keep the plants from starving? How did you go about building a chiller? I plan on building my own bubble buckets, ive also built my own cloner and flood tables in the past.
The more reserve capacity of the hydroponic system you're using, the longer your changeout interval can be. I have been waiting too long, and my capacity was 3 gal x 12 sites + 2 control buckets = 42 gallons. That would not last a week under hungry healthy plants.
My new setup of 27 gallon tubs doubles total RDWC water volume to nearly 90 gallons, so now four plants will have plenty to drink and feast on for quite some time.
One does not so much build the chiller itself as one builds the water supply and return lines throughout their grow, and then buys a chiller unit and installs it. The chiller is exactly the same as an air conditioning unit, save for one basic difference; instead of Freon passing through a radiator and air is blown through it to get cold, there is a coil of water pipe the Freon runs through to cool water flowing through the pipe. The chilled water then flows through your system to cool everything. EVERYTHING: water in RDWC, temperature control and dehumidification, all at once, all at substantial energy savings, especially if you run a larger facility.
As if that isn't far enough out there for ya, ask me about how my next climate control system is going to have fish in it. Seriously.
