Recently I have been growing custom Zinnias in the smaller AG3 machines . The seeds are the Swizzle and Cherry from Park's Seed Company and I find them successful for hydroponic growing. They don't get very tall and are sturdy plants.
The Petunias are doing very well. I am using Ultra Grow Liquid Nutrients rather than the solid nutrients which came with the Kit, and I notice a much better response from the plants this time around. The second picture is a pod of Zinnias from Park Seed which I thought I would try in the same machine....we'll see.....They came up overnight...literally, and seem to be thriving and sturdily growing.
We are growing steadily. On the next feeding I switch to the next stage of nutrients. However, I am not going to use AG solid nutes, but the Ultra Grow Liquid Nutes.
