By the way, the plants are Nirvana Afghani grown from three year old seeds!
who says old seeds don't grow! Thinking they would no longer be viable after all this time I put about 150 seeds in paper towel to ensure that I got some plants and about 90% of them sprouted after 3 days; DOH! I only had space for about 20 max so I've had to throw over 100 perfectly healthy seedlings away!! aagh!

P.S- notice the purple on the underside of the leaf on the seedling, strange.
I've seen these plants go purple before but only when I grew them outside the other year. I live in the UK so it was the cold that made them go purple I think.
