I have heard of the wort chiller idea before but how is this done when I have two rubbermaid bins, each acting as its own rez/grow medium. The grow is sog style, with two 2x4 ft bins in a 4x4ft tent. Each bin would have 15 plants sitting on top of the lid of course with the roots dangling down into the water, but I do not have a third bin that solely acts as a reservoir. Each bin is seperately maintained and acting as it's own reservoir for the plants to grow their roots down in to. Do i need a third bin acting as a reservoir feeding the other two bins for this to work??? I'm not sure why but I am having trouble understanding how to pull this off without just adding a third 45 gallon rubbermaid bin with no plants in it. I feel like then I would have to make this an under water recirculating dwc system, with the two rubbermaids with the plants in them connected together and then connected to a third bin acting as a seperate reservoir feeding the chilled water to the two bins inside of the tent. Am I wrong? Id like to not have to add a third bin, which would have to be outside of the tent, to feed the chilled water in through the two rubbermaid dwc bins and back out of the tent into the rez with the chiller again. Maybe I'm just dumb but is this the only option? Adding a third bin as a reservoir outsideof the tent and turning this into a recirculating system seems like the only option. Help me out here am I wrong?
