In getting ready to add some thermal mass in my green house I decided to do this by building a structure for a water tower. This structure will serve several purposes 2 300 gallon totes mounted on top will be painted black to absorb heat during the day the water in them will store the heat and radiate it off during the night time hours also eventually I will install an automatic gravity fed drip watering system to all of the grow beds as I build them and add plants but the hot water will not be dripped directly on the plants it will be cooled prior to this or fed into the soil through tubes in the bottoms of the beds
I will have 2 levels of grow beds under the tower itself to utilize otherwise wasted space.
