I got the starter package with three components and was happy with the results. the limiting factor on my balcony is the sun which disappears at 2pm. i used 3g/l soil both Grow and Bloom and the enhancer at 1g/l water every two weeks. Next year I'll prep the soil with 20% moms' compost and add 4g/l instead of 3 when the time comes for top dressing. Let's see what happens. I can't really tell how good or not the enhancer is really.
