I am growing in reused old living soil mix. Topped off the pot with new soil on the old giving a good 15cm of fresh soil.
None of the seeds cracked in a glass of water so I planted after 36 hours. 9 days later and something has actually popped!
I’ve been desperate to try Sour Stomper for a while as I know Daz had a hand in its creation and I haven’t had a chance to grow any Nightowl beans yet so this is the best of both worlds for me.
