What is Karma (17 Oct 2019)

Karma is one way to say "thank you" to a poster that was of particular good help to you on your posted question or problem. It's OPTIONAL and avoids cluttering up forum posts with many "Thank you's". You can also personally Thank the poster and show that they have helped you by clicking on "Thank you". The higher your karma value and the number of "Thank you's" is a fun measure of your value and status about TecHKnow. You can increase (or decrease) a persons' Karam by clicking on the "more" icon just below their user Picture/Avatar

We experimented years ago but soon went back to geraniums as they tick all the correct boxes.

I haven't actually tried it but I've read that basil works well.

I did wonder if say mint might work, but i've found a practical by Nuffield foundation which says Tradescantia and Impatiens can be used - i'm going to try later with our Tradescantia - i'll let everyone know if it works

Hi the Tradescantia does work but i've not yet managed to get the "in darkness" plant to work yet.

The problem with "in the dark plants" is how quickly they start making starch as soon as they come out of their box etc. I have heard this can be as little as 20 minutes..
