I managed to stabilise the bud rot in my main grow plants by monitoring everyday snipping out the least sign of mould and spraying with Potassium Bicarbonate. I also moved the green plants inside my poly-tunnel and use an 8" fan to give them some airflow.
Harvest day for the Duck tomorrow.
Thanks to everyone for their help and support.
I do have another thread active Indoor Winter Grow and hope to see you there.
