Hi Roy! I would be happy to recap. Yes, this is pure capillary action, watering mostly from the bottom. The only time I will top water is when adding GeoFlora Nutrients to the top once every 2 weeks. These are 7 gallon cloth containers filled with brand new Fox Farm Ocean Forest soil. I took a hand sized divot in the middle of the planter and planted my seedlings in Fox Farm Happy Frog in that divot, after lining the bottom of the hole with
@DYNOMYCO .
The SIP containers are 17 gallon tubs with the lids cut down so that they fit inside the tub as a false floor. I have 6" drain pipe set vertically under that floor to hold the weight and provide me with approximately a 6 gallon reservoir down below. 7.5" pieces of drain pipe were packed solid with soil and covered with a nylon stocking to hold the soil in place, and these two pieces stick up through 4.5" holes drilled in the false floor to be my wick feet. Soil barrier fabric was put into place to keep soil from falling through the 8-10 1" holes drilled in the false floor, and soil was added right up to the level of the wick feet so as to level out the planters and provide for a more even water exchange. The planters were pre-watered to runoff at the same time the rez was initially filled, so that the water flow connection was made from top to bottom.
The seeds were started in cups of water for 24 hours, then moved to paper towels in plastic sandwich bags on a temperature controlled seedling pad set to 75 degrees. When tails appeared, they were planted directly into the 7 gallon containers, where they will live the rest of their lives. At some point in the future, the entire containers will be moved to similar 17 gallon sip containers, but with only one wick foot, putting each plant in its own individual tote on wheels so that the plants can be separated a bit to eventually go into bloom and to be able to take advantage of twice as much rez per plant.
