This is a wonderful gift idea, I should know I was gifted this along with another of Plant Theatres kits.
The kit contains 6 packets of different herb seeds (basil, parsley, thyme, chives, coriander, rocket), 6 starter growing pots from peat, 6 peat expandable peat blocks, 6 plant markers and instructions. It contains all you need to get you started.
When you are ready you drop one of the peat blocks in water where it will expand (a lot!), squeeze
the water out and put it in the peat pot, drop in some seeds and cover with peat. And that’s all there is to it for a few days.
Once the herbs grow a bit (few centimetres) you can plant them either outside or inside into a bigger pot. What I love about this is that you do not need to put the herbs out of the original pot but plant them with it - since it is biodegradable.
