So today I am starting to assemble my ebb-flow system, 4 trays, a 17 gallon reservoir, 1/2" delivery and return lines. I am using 10:20 growing trays that I have modified with 1/2" bulkhead fittings, the reservoir is a simple 17 gallon HomeD tub with lid, I placed a 1/2" bulkhead at the bottom for a return and one at about 1" from the top as the pump delivery line. I cut a large hole in the top for the tub to fit a 6" hydroponic growing basket so I can add water without taking the lid off. The tubing I am using is clear 1/2" id tubing and the return line will also act as a sight glass to monitor water levels. So far the only catch has been the bulkhead fittings, they do not hold the tubing tight enough for my comfort, so I had to order a few 1/2" hose clamps (I need 12 now, so I ordered 25).
I checked the Mr. Stacky growing station today, it has some beautiful lettuce showing and even some spinach, this is working out well but the homemade reservoir only hold about 3 gallons and is going low about every other day now. They make a 16 gallon reservoir for them but at $75 it costs as much as all of my ebb-flow system including the pump... What can I say, I'm cheap... But the more I think about it the more tempted I become...
The outdoor garden is still doing well, but vine borers have found my squash and cucumbers. It may be time to pull the squash and replant spinach for the fall. The green onions are doing wonderfully, I planted 4 small patches of them and am finding I can harvest a couple of larger ones from each every week and they seem to just keep going...
