I was given a kit by an ex – i had expressed loads of interest in them. But, as someone who’s quite busy, and away a lot, I wasn’t able to keep up with the regularity of things to do with them (like, got to go in a bag at x weeks, for y number of weeks, or, mist daily for a week or two – I was away for weeks at a time).
I’m sure one could grow them without the rigidity that the instructions suggested, but I’m a bit funny with that kind of thing.
TLDR really interesting project and a cool gift, so long as the person you’re giving it to will be around enough to follow the instructions!
