Thanks. Those were done with a non-circulating system; Kratky(sp?). I've paused my planting right now because I'm building a more vertical system right now which will be a continuous flow type system. Since you do tomatoes, one thing that has been successful for me with them was starting them indoors after I clipped the branch from a bigger plant. I used something like a Dutch bucket to get them going, then moved them outdoors into our garden. With my same fertilizer formula, those same plants have produce incredible amounts of cherry tomatoes for three years now. We have to give some away every year because of the amount.
