I kept the germination at about 25C throughout, sprouted very quickly indeed.
I damaged the root transplanting to a pot and started a new one in case it was spoiled.
Despite losing a bit of root, everything went along just fine.
Initial germination done in a small converted cupboard using Sansi 15W grow light at about 10 in/25cm.
I'm keeping the other one, an Afghani #1 in case anything goes wrong, this is only my third grow.
