Has anyone tried hydroponics broccoli in a GH? I'm thinking of planting two in a 3' by 16" x 8" high plastic storage container with holes in the lid for net pots. I'd use Dyna-Grow 7-9-5, Liquid Grow. Would that formula work well to produce good heads? Half of the container would be for two broccoli plants (at two stages of growth), the other half for lettuce. What do you think?
