As I explained to Jeanie and Paul during our walk in the Royal Botanic Gardens the other day, while some people have a "green thumb", I most definitely have a black one. I've even killed a cactus, and that takes some doing!
Well, it looks like there's hope for me yet ... to the rescue comes herbi.
It's a hydroponic herb rack that has LEDs to tell you when the pH is high or low, when more nutrients are required and when the plants need watering.
Just so long as it has a klaxon that sounds if you ignore the indicators for too long, I should be fine :-) !!
